Chairman’s Letter

Dear Shareholder,

The Investor Shares of Vanguard U.S. Growth Fund returned 16.9% during the fiscal year ended August 31, 2005. The fund’s Admiral Shares1 returned 17.2%. The fund’s returns surpassed those of both its average peer and its index benchmark.

The table on page 1 summarizes the results for your fund, its primary benchmark, the average peer, and the broad U.S. stock market. You can find information on the fund’s per-share distributions during the period and its starting and ending net asset values in the second table on page 6. If you hold shares of the fund in a taxable account, you may wish to review the report on after-tax returns on page 23.

Stocks staged a stealth rally during the fiscal year

During the fiscal year, the Dow Jones Wilshire 5000 Composite Index, a broad measure of U.S. stock prices, returned 15.9%, with periods of pronounced gains punctuated by stretches of weakness. Smaller stocks outpaced their larger counterparts, and international stocks, particularly those from emerging markets, delivered outstanding returns.

As oil prices touched all-time highs, energy-related stocks were among the best performers. (It’s worth noting that, in inflation-adjusted terms, energy prices remained well below their early-1980s peaks.) Financial services and auto-industry stocks were among the weaker

performers. Banks and other lenders contended with a tricky interest rate environment, while the well-publicized financial woes of the auto giants and their suppliers weighed on their share prices.

In the bond market, yields defied expectations

In the fixed income markets, short-term interest rates rose sharply, while longer-term rates declined. Since June 2004, the Federal Reserve Board has steadily boosted its target for the federal funds rate in an effort to preempt inflationary pressures. During the 12 months, the yield of the 3-month U.S. Treasury bill, which closely follows the Fed’s moves, rose from 1.58% to 3.50%.

In several prior rate-boosting cycles—1984, 1988, and 1994—the yields of long-term bonds also followed the Fed’s lead. During the 2005 fiscal year, however, long-term yields fell. Because bond prices move in the opposite direction from yields, this unexpected “flattening of the yield curve” meant weak total returns for shorter-term bonds and stronger returns for longer-term securities. Corporate bonds outperformed government issues, and the Lehman Brothers Aggregate Bond Index, a measure of the broad investment-grade bond market, returned 4.1% for the 12 months.

Health care, tech holdings supported the fund’s strong returns

The U.S. Growth Fund produced solid returns throughout the fiscal year. During

the first half, the fund returned 9.7%. The gain was smaller in the second half, at 6.5%.

Both of the fund’s advisors carefully evaluate the large-capitalization stock universe to find those stocks that they believe offer the best combination of potential earnings growth and attractive valuations. Their complementary strategies typically lead both advisors to emphasize stocks from the information technology and health care sectors, where a large number of growth-oriented issues reside. On average, health care and technology stocks represented about 55% of fund assets during the fiscal year.

The advisors held a number of excellent performers in these two sectors, making a big impact on the fund’s 12-month result. In health care, the fund earned strong returns from relatively large holdings such as health services provider UnitedHealth Group and eyecare products company Alcon. UnitedHealth was bolstered by merger activity and record profits; Alcon saw excellent earnings growth. In technology, semiconductor firm Marvell Technology and broadband communications company Broadcom were leaders on the strength of solid earnings. Relative to the Russell 1000 Growth Index, the fund benefited from an overweighting in a handful of financial services stocks that performed well.

The advisors’ missteps were mainly errors of omission: The portfolio lacked some of the better-performing stocks in certain market segments, particularly the consumer discretionary and industrials sectors.

Long-term results sag under burden of two challenging years

Although the fund’s one-year performance was strong, we are disappointed by its long-term record. The “Total Returns” table on page 5 shows the fund’s average annual return for the ten years ended August 31 compared with the returns for the Russell 1000 Growth Index, the average large-cap growth fund, and the Dow Jones Wilshire 5000 Index. In all cases, the fund’s results fell short by a broad margin.

As I have noted for the past few years, the disappointing comparison results primarily from the fund’s poor returns in the 2001 and 2002 fiscal years. With time and solid performance such as the fund’s

2005 fiscal year return, we hope to see the gap close, producing a ten-year record more consistent with what we—and you—would expect from this investment over a long holding period. We remain confident in both your fund’s strategy and the advisory firms charged with executing it, Alliance Capital Management and William Blair & Company.

A carefully planned portfolio is the best defense

As we have counseled through the years, choosing and sticking with a carefully considered, balanced portfolio of stock, bond, and money market funds suited to your unique circumstances is critical to your portfolio’s long-term success. It is important that you remain comfortable and confident in the choices you make, and resist the temptation to change course in the face of short-term adversity.

We are pleased with the successful results that the U.S. Growth Fund posted in its current fiscal period, a performance that is more consistent with our expectations than the fund’s subpar long-term record. The fund’s stumbles in the aftermath of the stock market’s late-1990‘s boom nevertheless have some value as an object lesson about the need for diversification. Even though you may think your portfolio is positioned to accommodate whatever the financial markets may offer, things can go awry. The U.S. Growth Fund can provide exposure to fast-growing larger companies, but a prudent plan complements this holding with investments in other parts of the broad U.S. stock market, as well as in bonds and short-term reserves.

Thank you for your continued confidence in Vanguard.

Sincerely,

John J. Brennan
Chairman and Chief Executive Officer

Advisors’ Report

During the 12 months ended August 31, 2005, the Investor Shares of Vanguard U.S. Growth Fund returned 16.9% and the lower-cost Admiral Shares returned 17.2%. This performance reflects the combined efforts of your fund’s two independent advisors. The use of two advisors provides exposure to distinct, yet complementary, investment approaches, enhancing the diversification of your fund.

The advisors, the percentage of fund assets each manages, and a brief description of their investment strategies are presented in the table at the bottom of page 8. Each advisor has also prepared a discussion of the investment environment that existed during the 2005 fiscal year and how the portfolio positioning reflects this assessment.

Alliance Capital Management L.P.

Portfolio Manager: Alan Levi, Senior Vice President

The past 12 months have seen significant volatility in the stock market amid a generally favorable fundamental environment in terms of both economic expansion and corporate profits. Despite persistent increases in energy prices and the Federal Reserve Board’s less-accommodative monetary policy, the annualized rate of economic growth has ranged between 3.5% and 4.5%, led by business capital investment. Inflation, while rising, has remained moderate at 2.5%–3.0%. Corporate profit growth has been robust and, in many instances, better than anticipated, with generally strong cash flow. This has led many companies to reduce debt on their balance sheets, repurchase shares, and increase dividends.

Although prospects appear reasonable for continued healthy economic expansion and corporate profitability, significant challenges exist. They include escalating energy prices, potential inflation pressures, and the incremental cost impact of the recovery from Hurricane Katrina, for both the economy and the U.S. budget deficit. Accordingly, it seems appropriate to anticipate cyclical deceleration in corporate profits toward a more sustainable pace. Historically, such transitions have frequently been accompanied by heightened investor discrimination based upon perceived longer-term sustainability of earnings growth.

We have sought to orient our portion of the fund toward successful, well-managed leadership companies that have sustainable competitive advantages and superior prospective growth. Reflecting this, over the past five years the average revenue-per-share of our portfolio holdings grew at a compounded annual rate of 16.2%, comparing favorably with the 9.1% average for the Russell 1000 Growth Index. Similarly, five-year historical earnings-per-share growth was 28.3% for our portfolio holdings, double the 13.8% rate of the Russell 1000 Growth Index.

Over the past five years, we have seen an extraordinary compression in the valuations accorded to many leading, and historically consistent, growth companies. In a number of cases, this compression has occurred despite sustained strong earnings growth and fundamental success. Given these current valuations, which appear modest in historical terms, we anticipate that relative earnings growth will likely reassert itself as an increasingly important

determinant of stock performance over the next several years.

William Blair & Company, L.L.C.

Portfolio Manager: John F. Jostrand, CFA, Principal

For the fiscal year ended August 31, domestic equities moved broadly higher. The market vacillated between optimism, prompted by better-than-expected corporate earnings and an improving employment outlook, and concerns about the impact of lofty energy prices and rising interest rates. Despite investors’ relatively defensive posture, indicated by the rise in stock prices in the consumer staples, utilities, and materials sectors, there was periodic interest in biotechnology and select technology stocks—a possible indication that growth investing has signs of life, following five years of outperformance by value. In fact, during the past 12 months, our portfolio enjoyed strong returns from growth-oriented health care stocks such as Amgen, Alcon, and UnitedHealth Group.

The economic environment during recent periods has offered exceptional opportunities for strong earnings growth and historically high corporate profitability. Companies across the board have benefited from this environment, which has provided little delineation between a mediocre firm and a great one. As the economic cycle matures into a phase of slowing growth, companies with strong managements that have demonstrated experience in controlling costs and appropriately deploying capital in a tougher environment are likely to become increasingly differentiated.

Our fundamental approach continues to uncover quality growth opportunities in health care and information technology, which continue to have the highest weightings in our portfolio. We are not finding compelling growth opportunities in the financials sector, and are selective with respect to consumer-related stocks in the current environment.

Notes to Financial Highlights

Vanguard U.S. Growth Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund's minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund's pricing time but after the close of the securities' primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund's net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the financial statements. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. Alliance Capital Management L.P. and William Blair & Company, L.L.C., each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fee for Alliance Capital Management is subject to quarterly adjustments based on performance for the preceding three years relative to the Russell 1000 Growth Index. Effective March 1, 2005, the basic fee for William Blair & Company is subject to quarterly adjustments based on performance since June 1, 2004, relative to the Russell 1000 Growth Index.

The Vanguard Group manages the cash reserves of the portfolio on an at-cost basis.

For the year ended August 31, 2005, the aggregate investment advisory fee represented an effective annual basic rate of 0.15% of the fund's average net assets before a decrease of $1,318,000 (0.02%) based on performance.

C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $739,000 to Vanguard (included in Other Assets), representing 0.01% of the fund's net assets and 0.74% of Vanguard's capitalization. The fund's trustees and officers are also directors and officers of Vanguard.

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund's management and administrative expenses. For the year ended August 31, 2005, these arrangements reduced the fund's expenses by $1,580,000 (an annual rate of 0.03% of average net assets).

E. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During 2002, the fund elected to use a provision of the Taxpayer Relief Act of 1997 to mark-to-market certain appreciated securities held on January 1, 2001; such securities were treated as sold and repurchased, with unrealized gains of $912,491,000 becoming realized and reducing the fund's capital loss carryforward, for tax purposes. The mark-to-market had no effect on realized gains or unrealized appreciation for financial statement purposes; it created a difference between the cost of investments for financial statement and tax purposes, which reverses as the securities are sold. The fund realized gains on the sale of these securities through August 31, 2004, and subsequently during the year

ended August 31, 2005, of $768,896,000 and $143,595,000, respectively, for financial statement purposes, which were included in fiscal 2001 mark-to-market gains for tax purposes. All affected securities have been sold as of August 31, 2005.

For tax purposes, at August 31, 2005, the fund had $10,060,000 of ordinary income available for distribution. The fund had available realized losses of $7,169,803,000 to offset future net capital gains of $3,610,329,000 through August 31, 2010, $2,548,333,000 through August 31, 2011, $887,490,000 through August 31, 2012, and $123,651,000 through August 31, 2013.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $854,314,000, consisting of unrealized gains of $1,018,355,000 on securities that had risen in value since their purchase and $164,041,000 in unrealized losses on securities that had fallen in value since their purchase.

At August 31, 2005, the aggregate settlement value of open futures contracts expiring through December 2005 and the related unrealized appreciation (depreciation) were:

		($000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)
Nasdaq 100 E-Mini	5,405	171,230	6,879

S&P 500 E-Mini	170	10,382	101

S&P 500	17	5,209	42

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

F. During the year ended August 31, 2005, the fund purchased $2,165,283,000 of investment securities and sold $3,502,509,000 of investment securities other than temporary cash investments.

G. Capital share transactions for each class of shares were:

Report of Independent Registered
Public Accounting Firm

To the Shareholders and Trustees of Vanguard U.S. Growth Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard U.S. Growth Fund (the “Fund”) at August 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2005 by correspondence with the custodian and broker and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2005 tax information (unaudited) for Vanguard U.S. Growth Fund

This information for the fiscal year ended August 31, 2005, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $19,543,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 100% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect the reduced tax rates on ordinary income (including qualified dividend income) and short-term capital gains that became effective as of January 1, 2003, and on long-term capital gains realized on or after May 6, 2003. To calculate qualified dividend income, we used actual prior year figures and estimates for 2005. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.)

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

Vanguard’s Policies for Managing Changes
to Investment Advisory Arrangements

The boards of trustees of the Vanguard funds and Vanguard have adopted practical and cost-effective policies for managing the funds' arrangements with their unaffiliated investment advisors, as permitted by an order from the U.S. Securities and Exchange Commission (SEC).

Background
In 1993, Vanguard was among the first mutual fund companies to receive permission from the SEC to streamline the process of changing a fund’s investment advisory arrangements. In essence, the SEC allowed the boards of the Vanguard funds to enter into new or revised advisory arrangements without the delay and expense of a shareholder vote. This ability, which is subject to a number of SEC conditions designed to protect shareholder interests, has saved the Vanguard funds and their shareholders several million dollars in proxy costs since 1993. It has also enabled the funds’ trustees to quickly implement advisory changes in the best interest of shareholders.

Over the past 12 years, many mutual fund companies have followed Vanguard’s lead in obtaining similar arrangements from the SEC. As the SEC gained experience in this area, it granted more flexible conditions to other fund companies than it had granted to Vanguard in 1993. Consequently, Vanguard asked the SEC for permission to update its policies concerning its arrangements with outside investment advisors.

Our updated policies
The SEC has granted Vanguard permission to follow even more practical and cost-effective policies in managing the Vanguard funds’ investment advisory arrangements:

Statement of Additional Information (SAI). Vanguard funds that employ an unaffiliated investment advisor will now show advisory fee information on an aggregate basis in their SAIs. (A fund’s SAI provides more detailed information than its prospectus and is available to investors upon request.) Previously, Vanguard had been required to present separate fee schedules for each unaffiliated advisor. Each fund’s SAI will also include the amount paid by the fund for any investment advisory services provided on an at-cost basis by Vanguard. Reporting advisory fees in this manner is the same approach used by other fund companies that have received SEC exemptive orders.

Shareholder notification. Like other fund companies, Vanguard now has up to 90 days after a fund enters into a new advisory agreement to notify shareholders of the change. Previously, Vanguard was required to notify shareholders at least 30 days before any such change, if possible. In practice, Vanguard expects to continue notifying shareholders of advisory changes as soon as is practical, taking into account opportunities to reduce postage expenses by enclosing notices with previously scheduled mailings.

Redemption fees. Some Vanguard funds charge a redemption fee, which typically applies to shares redeemed within a certain period following purchase. Previously, the Vanguard funds were required to waive their redemption fees for 90 days after giving notice of an advisory change. The SEC has not generally applied this requirement to other fund companies and has now eliminated it for Vanguard. (Redemption fees—which are paid to the fund, not to Vanguard—are designed to ensure that short-term investors pay their fair share of a fund’s transaction costs.)

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The table below illustrates your fund’s costs in two ways:

1. Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

2. Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Six Months Ended August 31, 2005

U.S. Growth Fund	Beginning Account Value 2/28/2005	Ending Account Value 8/31/2005	Expenses Paid During Period1
Based on Actual Fund Return

Investor Shares	$1,000.00	$1,065.44	$2.92

Admiral Shares	1,000.00	1,066.75	1.67

Based on Hypothetical 5% Yearly Return

Investor Shares	$1,000.00	$1,022.38	$2.85

Admiral Shares	1,000.00	1,023.59	1.63

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

1 The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.56% for Investor Shares and 0.32% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the current fund prospectus.

Trustees Renew Advisory Agreements

The board of trustees of Vanguard U.S. Growth Fund has renewed the fund’s investment advisory agreements with its two advisors: Alliance Capital Management L.P. and William Blair & Company, L.L.C. The board determined that the retention of the advisors was in the best interests of the fund and its shareholders.

The board decided to renew the agreements with Alliance and William Blair based upon its most recent evaluation of each firm’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the agreements. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services

The board considered the quality of the fund’s investment management over both short- and long-term periods and took into account the organizational depth and stability of each firm.

• Alliance Capital Management L.P. Alliance is a leading global investment management firm founded in 1971. Alliance’s portion of the fund is managed by the Discipline Growth Team, which is led by Alan Levi. Mr. Levi has worked in investment management since 1973 and has been an advisor to the fund since 2002. The team consists of six portfolio managers with an average of 23 years of experience.

• William Blair & Company, L.L.C. William Blair, which is an independently owned full-service investment management firm founded in 1935, consists of 31 portfolio managers averaging over 25 years of experience. William Blair’s portion of the fund is managed by the Large Growth Team, which is co-led by John F. Jostrand. Mr. Jostrand has been in investment management since 1979 and has been an advisor to the fund since 2004.

The board continually monitors the investment management of the fund, and, noting strong recent performance and disappointing performance in some of the past several years, has taken steps in recent years to adjust the fund’s investment management team. In 2001, the board replaced the fund’s previous advisor with its current lead advisor, Alliance. The board concluded that Alliance brings an experienced and tested management team to the fund with competitive long-term results in large-cap growth stock investing. In 2004, the board took the additional step of adopting a multimanager investment advisory approach for the fund. Under the multimanager structure, approximately 65%–70% of the fund’s assets are managed by Alliance and approximately 30%–35% are managed by William Blair.

Upon renewing the advisor’s investment management agreements in 2005, the board concluded that both advisors have experienced and qualified teams of portfolio managers and analysts dedicated to the fund. Further, the board concluded that one of the benefits of the multimanager structure is the ability to diversify the holdings in the portfolio, with the aim of reducing stock-specific risk within the fund. The investment approaches of both advisors, in tandem, should provide diversification benefits for shareholders that would not be available if either advisor solely managed the fund.

Investment performance

The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of relevant benchmarks and peer groups.

The board considered that the fund’s recent investment performance has been very strong but the performance of the fund has been disappointing in some of the past several years. The board concluded that (1) at this time the current investment management team is the right one to advise the fund, and the advisory agreements should be renewed; and (2) the fund’s recent results have been more encouraging. In considering the fund’s short- and long-term performance, the board noted that for any actively managed fund, underperformance due to subpar stock selection by the fund’s advisor is a possibility. This is particularly true for a fund like U.S. Growth Fund, which maintains a fairly concentrated portfolio of approximately 70 stocks, with top ten holdings typically comprising 30% of fund assets. This investment approach leads at times to ups and downs that are steeper than those of the broad market and means that there is a risk that the fund’s returns could be hurt disproportionately by poor performance of a handful of stocks. Information about the fund’s performance, including some of the data considered by the board, can be found in the Performance Summary section of this report.

Cost

The fund’s expense ratio was far below the average expense ratio charged by funds in its peer group. The fund’s advisory fees were also well below the peer-group average. Information about the fund’s expense ratio appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section, which also includes information about the advisory fee rate. The board did not consider profitability of the advisors in determining whether to approve the advisory fees, because both Alliance and William Blair are independent of Vanguard and the advisory fees are the result of arm’s-length negotiations.

The benefit of economies of scale

The board concluded that the fund’s shareholders benefit from economies of scale because of breakpoints in the fund’s advisory fee schedules. The breakpoints reduce the effective rate of the fees as the fund’s assets managed by Alliance and William Blair increase.

The advisory agreements will continue for one year and are renewable by the fund’s board after that for successive one-year periods.

Glossary

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund’s equity assets represented by stocks or depositary receipts of companies based outside the United States.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

Chairman’s Letter

Dear Shareholder,

Owing largely to swings in the value of the U.S. dollar, investors in international markets enjoyed stellar gains in the first half of the fiscal year, after which returns were modest. Vanguard International Growth Fund reflected this pattern, with a fiscal-year return of 23.5% for its Investor Shares, of which just 3.1 percentage points came in the year’s second half. The lower-cost Admiral Shares¹returned 23.8% for the period, which ended August 31, 2005.

The fund’s unmanaged benchmark index, the Morgan Stanley Capital International Europe, Australasia, Far East (MSCI EAFE) Index, gained 23.6% for the fiscal year. By comparison, the broad U.S. stock market returned 15.9% for the 12 months, as measured by the Dow Jones Wilshire 5000 Composite Index.

The table on page 1 shows the return of the fund, its benchmark, its average peer, and the MSCI All Country World Index ex USA, the broadest proxy for international stocks, including those from emerging markets.

The fund’s shortfall relative to peers and the broader index came from its lighter weightings in commodities companies, which were the period’s strongest gainers, and its selections among technology and industrial companies in Japan and Germany.

1 Admiral^(TM)Shares: A lower-cost class of shares available to many longtime shareholders and to those with significant investments in the fund.

The total returns are based on the changes in capital plus reinvested distributions. The fund’s distributions and share prices at the beginning and end of the period are shown in the table on page 7. For those who hold the fund in a taxable account, page 29 shows after-tax returns for investors in the highest tax bracket.

U.S. stocks staged a stealth rally during the fiscal year

The U.S. stock market, as measured by the Dow Jones Wilshire 5000 Index, returned 15.9% during the fiscal year, with periods of pronounced gains punctuated by stretches of weakness. Despite its strong 12-month result, the U.S. market looked almost tepid in comparison with markets abroad—particularly emerging markets, which provided U.S.-based investors with outstanding gains. The U.S. dollar retreated for half the period, as government deficits and trade imbalances weighed on the greenback, then began surging in the spring as short-term interest rates rose relative to other countries.

As oil prices touched all-time highs, energy-related stocks were among the best performers globally. (It’s worth noting that, in inflation-adjusted terms, energy prices remained below their early-1980s peaks.) In the United States, financial services and auto-industry stocks were among the weaker performers. Banks and other lenders contended with a tricky interest rate environment, while the well-publicized financial woes of the auto giants and their suppliers weighed on their share prices. By contrast, financial services, consumer staples, and commodities were strong performers abroad, partly due to higher growth rates in Asia.

In the U.S. bond market, yields defied expectations

In the U.S. fixed income market, short-term interest rates rose sharply while longer-term rates declined. Since June 2004, the Federal Reserve Board has steadily boosted its target for the federal funds rate in an effort to preempt inflationary pressures. During the 12 months, the yield of the 3-month U.S. Treasury bill, which closely follows the Fed’s moves, rose from 1.58% to 3.50%.

The fund’s gains were spread widely across economic sectors

The International Growth Fund benefited from reasonably strong economic growth around the globe and the relentless rise in energy prices. The fund enjoyed strong performance across sectors, with its energy stocks soaring more than 50% and its utilities, materials, and consumer staples stocks all gaining roughly 30% for the year. Six of the fund’s most heavily weighted holdings accounted for a disproportionate share of the overall gain: Brazilian and British energy companies Petróleo Brasileiro and BG Group; British retailer Tesco and wireless phone company Vodafone Group; French utility Suez; and South Korean conglomerate Samsung. The fund’s holdings in emerging countries performed very well, particularly in Asia.

For U.S.-based investors, performance abroad also depends on changes in the value of the U.S. dollar. The past year has shown dramatically just how important this factor can be. In local-currency terms, the MSCI EAFE Index gained 12.5% in the first six months and 9.7% in the second, but those results looked far different when translated into dollars: a 21.2% gain during the first half, when the dollar lost value, and a 2.0% gain in the second half, when the dollar surged as short-term interest rates rose in the United States. The

Average International Fund	5.7	17,438

MSCI All Country World Index ex USA	6.3	18,346

International Growth Fund likewise booked much of its 12-month gain in the first half.

Relative to the MSCI EAFE Index, the fund lost the most ground in Europe, partly by skipping or underweighting some strong performers within the energy and financial sectors. In addition, the fund had large holdings in a few companies that either posted negative returns (including Japan’s Ricoh and East Japan Railway) or produced “weak” gains while most companies roared ahead. Germany’s Siemens, which gained 13% for the period, is an example of the latter.

Your fund has delivered during a decade of see-saw returns

International markets have outgained U.S. markets by a wide margin for the past three calendar years and so far in 2005—a complete contrast to the trend in the mid-1990s, when U.S. markets soared and international markets floundered. The International Growth Fund’s ten-year performance reflected this down-and-up sequence, resulting in an average annual gain of 6.6% over the decade ended August 31. As the table on page 4 demonstrates, over those years the fund outpaced both its benchmark index and its average peer. In fact, a hypothetical investor committing $10,000 to the fund would have amassed $18,963 at the end of the ten years. That is $1,525 (or 8.7%) more than the average gain of peer funds over the same period.

The credit for this admirable performance goes largely to the man who has served fund shareholders since the fund’s 1981 inception—Richard Foulkes, vice chairman of Schroder Investment Management North America Inc. Richard will retire at the end of October after a distinguished career navigating the occasionally treacherous shoals of international markets. World events—the rise and subsequent collapse of the Japanese stock market, the march of globalization, and shockwaves from international currency panics, to name just a few—have all challenged his steady hand. He will be missed. I am personally grateful for his dedication to the fund’s investors, and I am confident that the fund will continue to benefit from the team of talented and experienced managers he has assembled to assume his duties.

Having two investment advisors provides complementary management styles that further diversify the portfolio. Each manager’s share of the portfolio is shown in the table on page 5.

How international investments can aid your portfolio

As I mentioned earlier, your returns from this fund depend in part on the performance of large-capitalization growth stocks internationally and also the fluctuations of the U.S. dollar. Neither is directly correlated with the performance of the U.S. stock market—or the bond markets, for that matter. That is why the International Growth Fund can play an important role in diversifying your portfolio. Remember that diversification—holding a mix of stock funds, bond funds, and cash reserves appropriate for your risk tolerance and investment goals—can allow you to benefit over time as economies and markets around the world take their turns as the engines of economic progress. An important part of maintaining a diversified portfolio is rebalancing when one asset class has enjoyed prolonged outperformance. The strong returns of international funds in recent years may necessitate such a portfolio checkup.

A final point: costs matter. Over time, a higher expense ratio, sales commissions, and excessive transaction costs can reduce the share of returns that reaches mutual fund investors. Vanguard strives to provide the lowest expense ratios possible while maintaining high standards for investment management and client service. As you can see in the table below, the International Growth Fund carries an expense ratio that is less than half the average cost borne by competing funds. The steep difference in costs—like diversification—can help you improve your returns over time.

Thank you for entrusting your hard-earned money to Vanguard.

Sincerely,

John J. Brennan
Chairman and Chief Executive Officer

Advisor’s Report

International stock markets rose strongly over the year ending August 31, 2005. The Investor Shares of Vanguard International Growth Fund returned 23.5% to shareholders, which was in line with the 23.6% rise in the MSCI EAFE Index and slightly behind the 24.1% gain of the average international fund.

This report focuses on the position of the portfolio managed by Schroder Investment Management North America, representing 71% of the fund’s assets as of August 31, 2005.

The investment environment

With the esoteric exception of Venezuela, every stock market I follow around the world rose by more than 10% in dollar terms over the last fiscal year. Truly, we were in a global bull market fueled by strong corporate profit increases and easy monetary conditions. In this context, the U.S. large-capitalization market, like the Japanese market, was relatively disappointing, since both rose “only” 12% to 13%. European markets rose 26% in aggregate, and emerging markets by 42%. In the past I have highlighted the apparent paradox whereby current global economic growth relies largely on growth in the United States and China, yet better returns are earned elsewhere. Clearly, this stimulates exports from around the globe, and that is precisely what we have seen, notably in a wide range of industrial goods, materials, and natural resources. In addition, compared with U.S. firms, European and Japanese companies take longer to cut costs, so the benefits of higher productivity are still coming through in those markets while unit labor costs in the United States are now beginning to threaten corporate profit growth again.

Strong exports should have fed through into higher employment, but this has happened less than expected, as companies fight to keep costs down; consequently consumers outside the United States have typically been very cautious spenders. Japanese exports have decelerated sharply in recent months in tandem with China’s imports of manufactured goods, but full-time jobs have risen steadily in Japan throughout 2005. This is encouraging for that nation’s domestic demand, but we doubt that it will continue. Such trends are less discernible in Europe, where the labor market has been flat, leaving unemployment at 8.6% in the Eurozone, for example, and where real retail sales have been growing at under 1% per annum.

Japan and Germany have reacted better to these pressures than France and Italy, with economic reform firmly back on the political agenda. France, sadly, is still increasing protection for its industries. Italy desperately needs reform but seems to be heading in the opposite direction.

European markets, and notably the United Kingdom, have benefited from a wave of corporate takeover activity, from both companies and private equity investors. While corporate cash flows remain strong and money remains easily

accessible, this trend looks set to continue. This is particularly important in the United Kingdom, where the economic cycle has already started to decelerate sharply, particularly in the housing market, a situation that is materially affecting consumer spending.

The U.S. dollar was a most extraordinary performer during the past fiscal year. In the first six months, as expected, it fell by 7% under the burden of the growing deficit in the balance of foreign payments. But in the second half of the year, demand for the dollar surged back as holders favored the strength of the U.S. economy and the prospect of higher interest rates. The fickle nature of foreign exchange markets has long been a characteristic of international investing.

Our successes

Our portfolio is barbelled with aggressive positions in emerging markets to capture the best growth environments on the planet and more defensive positions in developed markets, reflecting their struggle to find top-line growth. Both elements of this policy worked well for us over the year, with emerging-market stocks producing returns approximately twice as high as the rest of the portfolio and our stocks in all but one defensive sector performing strongly.

In particular, our long-standing policy of favoring technology stocks in Asia (notably Korea, Taiwan, and India) over Europe paid off again this year.

Our failures

We correctly avoided pharmaceutical shares generally in the first half of the year for reasons that most investors noted. When I wrote to you six months ago, our view was that most of the bad news about products and the regulatory environment was priced in, and we were starting to buy again. However, our stock selection was disappointing, particularly in view of the ongoing poor performance of AstraZeneca.

I was also surprised by the strong performance of financial stocks in Japan and the Eurozone. We had far too little invested in this highly leveraged sector, anticipating that weak growth in domestic demand, which did transpire, would result in higher provisioning for delinquent loans and lower loan growth, neither of which transpired. That said, the stocks that we did hold performed very well.

Finally, the portfolio continued to suffer from the absence of commodity stocks, which typically rose by more than 50% over the year, as supply struggled to keep up with demand.

Our positioning

My comments above underline the portfolio’s positioning for a slowdown in global economic growth. The assumption evident in stock markets that strong profitability and cash flows will continue in Europe and, increasingly, Japan surprises me at a time when access to capital for expansion is relatively easy. Central bankers’ disinterest in rising rates

shows a lack of conviction that strong growth lies ahead. Our central expectation is that the global economy will muddle through despite its excesses and imbalances, but the risks are to the downside. The bias in the portfolio toward strongly financed companies with leading market positions will help mitigate these risks if need be.

This is my last letter to shareholders after 24 years at the helm of International Growth. I have been proud to manage money forVanguard and thank you all for the trust that you placed in me. I also wish to thank my team members at Schroders for all the help they have given me and wish them “Godspeed” as they sail on without me.

Respectfully,

Richard Foulkes, Executive Vice President
Schroder Investment Management

Notes to Financial Statements

Vanguard International Growth Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in securities of foreign issuers, which may subject it to investment risks not normally associated with investing in securities of United States corporations. The fund offers two classes of shares, Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, servicing, tenure, and account-size criteria.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued at their fair values calculated according to procedures adopted by the board of trustees. These procedures include obtaining quotations from an independent pricing service, monitoring news to identify significant market- or security-specific events, and evaluating changes in the values of foreign market proxies (for example, ADRs, futures contracts or exchange-traded funds), between the time the foreign markets close and the fund’s pricing time. When fair-value pricing is employed, the prices of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Foreign Currency: Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates on the valuation date as employed by Morgan Stanley Capital International (MSCI) in the calculation of its indexes. As part of the fund’s fair value procedures, exchange rates may be adjusted if they change significantly before the fund’s pricing time but after the time at which the MSCI rates are determined (generally 11:00 a.m. Eastern time).

Realized gains (losses) and unrealized appreciation (depreciation) on investment securities include the effects of changes in exchange rates since the securities were purchased, combined with the effects of changes in security prices. Fluctuations in the value of other assets and liabilities resulting from changes in exchange rates are recorded as unrealized foreign currency gains (losses) until the asset or liability is settled in cash, when they are recorded as realized foreign currency gains (losses).

3. Futures and Forward Currency Contracts: The fund uses S&P ASX 200 Index, Dow Jones EURO STOXX 50 Index, FTSE 100 Index, and Topix Index futures contracts to a limited extent, with the objective of maintaining exposure to the European and Pacific stock markets while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the portfolio and the prices of futures contracts, and the possibility of an illiquid market.

The fund also enters into forward currency contracts to provide the appropriate currency exposure related to any open futures contracts. The fund’s risks in using these contracts include movement in the values of the foreign currencies relative to the U.S. dollar and the ability of the counterparties to fulfill their obligations under the contracts.

Futures and forward currency contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the financial statements. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized gains (losses) on futures or forward currency contracts.

4. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

5. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

6. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

7. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Fees assessed on redemptions of capital shares are credited to paid-in capital.

B. Schroder Investment Management North America Inc. and Baillie Gifford Overseas Ltd. each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fee of each advisor is subject to quarterly adjustments based on performance relative to the Morgan Stanley Capital International Europe, Australasia, Far East Index. For Schroder, the adjustments are based on performance for the preceding three years, and for Baillie Gifford the adjustments are based on performance since December 1, 2003.

The Vanguard Group manages the cash reserves of the fund on an at-cost basis.

For the year ended August 31, 2005, the aggregate investment advisory fee represented an effective annual basic rate of 0.13% of the fund’s average net assets, before a decrease of $1,260,000 (0.01%) based on performance.

C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $1,223,000 to

Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 1.22% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. The fund’s custodian bank has also agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the year ended August 31, 2005, these arrangements reduced the fund’s management and administrative expenses by $1,824,000 and custodian fees by $7,000. The total expense reduction represented an effective annual rate of 0.02% of the fund’s average net assets.

E. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended August 31, 2005, the fund realized net foreign currency losses of $445,000, which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized losses to undistributed net investment income. Certain of the fund’s investments are in securities considered to be “passive foreign investment companies,” for which any unrealized appreciation and/or realized gains are required to be included in distributable net income for tax purposes. The fund realized gains on sales of “passive foreign investment companies” of $4,119,000, which have been included in current and prior periods’ taxable income and distributions to shareholders; accordingly such gains have been reclassified from accumulated net realized losses to undistributed net investment income.

For tax purposes, at August 31, 2005, the fund had $149,815,000 of ordinary income available for distribution. The fund had available realized losses of $25,164,000 to offset future net capital gains through August 31, 2011.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $2,115,114,000, consisting of unrealized gains of $2,197,824,000 on securities that had risen in value since their purchase and $82,710,000 in unrealized losses on securities that had fallen in value since their purchase.

At August 31, 2005, the aggregate settlement value of open futures contracts expiring in September 2005 and the related unrealized appreciation (depreciation) were:

		($000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)

Dow Jones EURO STOXX 50 Index	2,886	116,418	3,498

FTSE 100 Index	1,017	97,081	4,684

Topix Index	701	80,497	8,048

S&P ASX 200 Index	345	28,868	1,238

At August 31, 2005, the fund had open forward currency contracts to receive and deliver currencies as follows:

	Contract Amount (000)				Unrealized Appreciation (Depreciation)
Contract Settlement Date	Receive		Deliver		($000)
9/21/2005	EUR	95,152	USD	117,118	1,388

9/21/2005	GBP	53,093	USD	95,450	(1,106)

AUD—Australian dollar
EUR—Euro
GBP—British pound
JPY—Japanese yen
USD—U.S. dollar

Unrealized appreciation (depreciation) on open forward currency contracts is treated as realized gain (loss) for tax purposes.

The fund had net unrealized foreign currency gains of $37,000 resulting from the translation of other assets and liabilities at August 31, 2005.

F. During the year ended August 31, 2005, the fund purchased $5,029,264,000 of investment securities and sold $4,248,655,000 of investment securities other than temporary cash investments.

G. The market value of securities on loan to broker/dealers at August 31, 2005, was $399,176,000, for which the fund held cash collateral of $412,448,000.

H. Capital share transactions for each class of shares were:

Report of Independent Registered
Public Accounting Firm

To the Shareholders and Trustees of Vanguard International Growth Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard International Growth Fund (the “Fund”) at August 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2005 by correspondence with the custodian and brokers, and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Your Fund’s After-Tax Returns

The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

Average Annual Total Returns International Growth Fund Investor Shares¹ Periods Ended August 31, 2005	One Year	Five Years	Ten Years
Returns Before Taxes	23.54%	0.72%	6.61%
Returns After Taxes on Distributions	23.14	0.00	5.69
Returns After Taxes on Distributions and Sale of Fund Shares	15.59	0.28	5.32

1 Total returns do not reflect the 2% fee assessed on redemptions of shares purchased on or after June 27, 2003, and held for less than two months.

About Your Fund’s Expenses

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The table below illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Six Months Ended August 31, 2005 International Growth Fund	Beginning Account Value 2/28/2005	Ending Account Value 8/31/2005	Expenses Paid During Period¹
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,031.20	$3.02
Admiral Shares	1,000.00	1,032.71	2.00
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,022.23	$3.01
Admiral Shares	1,000.00	1,023.24	1.99

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.59% for Investor Shares and 0.39% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Note that the expenses shown in the table on the previous page are meant to highlight and help you compare ongoing costs only; they do not include your fund’s low-balance fee or the 2% fee that applies to shares purchased on or after June 27, 2003, and held for less than two months. These fees are fully described in the prospectus. If the fees were applied to your account, your costs would be higher. Your fund does not carry a “sales load.”

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

Trustees Renew Advisory Agreements

The board of trustees of Vanguard International Growth Fund has renewed the fund’s investment advisory agreements with its two advisors, Schroder Investment Management North America Inc. and Baillie Gifford Overseas Ltd., as well as the subadvisory agreement with Schroder Investment Management North America Limited. The board determined that the retention of the advisors was in the best interests of the fund and its shareholders.

The board decided to renew the agreements with Schroder and Baillie Gifford based upon its most recent evaluation of each firm’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the agreements. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services
The board considered the quality of the fund’s investment management over both short- and long-term periods and took into account the organizational depth and stability of each firm. The board considered the following:

• Schroder Investment Management North America Inc. Schroder plc, the parent company of Schroder Inc., has investment management experience dating back to 1926. Schroder Inc. selects attractive growth stocks for the fund from developed and emerging markets outside the United States. Richard Foulkes has worked in investment management since 1961 and has managed the fund since its inception. As previously announced, Mr. Foulkes will retire on October 31, 2005, and his responsibilities will be assumed by Virginie Maisonneuve and Matthew Dobbs. Ms. Maisonneuve, who joined Schroder in 2004, has nearly two decades of portfolio management experience. Mr. Dobbs has worked closely with Mr. Foulkes on the fund since 1999.

• Baillie Gifford Overseas Ltd. Baillie Gifford is a unit of Baillie Gifford & Co., which was founded in 1908 and is one of the largest independently owned investment management firms in the United Kingdom. Baillie Gifford Overseas builds a diversified portfolio of high-quality, non-U.S. growth stocks from developed and emerging markets. James K. Anderson has worked in investment management since 1983 and has managed a portion of the fund’s assets since 2003.

The board concluded that each advisor’s experience, stability, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance
The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of relevant benchmarks and peer groups. Each advisor has carried out its investment strategy in disciplined fashion, and the results provided by each have been in line with expectations. Information about the fund’s performance, including some of the data considered by the board, can be found in the Performance Summary section of this report.

Cost
The fund’s expense ratio was far below the average expense ratio charged by funds in its peer group. The fund’s advisory fees were also well below the peer-group average. Information about the fund’s expense ratio appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section, which also includes information about the advisory fee rate. The board did not consider profitability of the advisors in determining whether to approve the advisory fees, because both Schroder and Baillie Gifford are independent of Vanguard and the advisory fees are the result of arm’s-length negotiations.

The benefit of economies of scale
The board concluded that the fund’s shareholders benefit from economies of scale because of breakpoints in the fund’s advisory fee schedules. The breakpoints reduce the effective rate of the fees as the fund’s assets managed by Schroder and Baillie Gifford increase.

The advisory agreements will continue for one year and are renewable by the fund’s board after that for successive one-year periods.

Vanguard’s Policies for Managing Changes to Investment Advisory Arrangements

The boards of trustees of the Vanguard funds and Vanguard have adopted practical and cost-effective policies for managing the funds’ arrangements with their unaffiliated investment advisors, as permitted by an order from the U.S. Securities and Exchange Commission (SEC).

Background

In 1993, Vanguard was among the first mutual fund companies to receive permission from the SEC to streamline the process of changing a fund’s investment advisory arrangements. In essence, the SEC allowed the boards of the Vanguard funds to enter into new or revised advisory arrangements without the delay and expense of a shareholder vote. This ability, which is subject to a number of SEC conditions designed to protect shareholder interests, has saved the Vanguard funds and their shareholders several million dollars in proxy costs since 1993. It has also enabled the funds’ trustees to quickly implement advisory changes in the best interest of shareholders.

Over the past 12 years, many mutual fund companies have followed Vanguard’s lead in obtaining similar arrangements from the SEC. As the SEC gained experience in this area, it granted more flexible conditions to other fund companies than it had granted to Vanguard in 1993. Consequently, Vanguard asked the SEC for permission to update its policies concerning its arrangements with outside investment advisors.

Our updated policies

The SEC has granted Vanguard permission to follow even more practical and cost-effective policies in managing the Vanguard funds’ investment advisory arrangements:

Statement of Additional Information (SAI). Vanguard funds that employ an unaffiliated investment advisor will now show advisory fee information on an aggregate basis in their SAIs. (A fund’s SAI provides more detailed information than its prospectus and is available to investors upon request.) Previously, Vanguard had been required to present separate fee schedules for each unaffiliated advisor. Each fund’s SAI will also include the amount paid by the fund for any investment advisory services provided on an at-cost basis by Vanguard. Reporting advisory fees in this manner is the same approach used by other fund companies that have received SEC exemptive orders.

Shareholder notification. Like other fund companies, Vanguard now has up to 90 days after a fund enters into a new advisory agreement to notify shareholders of the change. Previously, Vanguard was required to notify shareholders at least 30 days before any such change, if possible. In practice, Vanguard expects to continue notifying shareholders of advisory changes as soon as is practical, taking into account opportunities to reduce postage expenses by enclosing notices with previously scheduled mailings.

Redemption fees. Vanguard International Growth Fund charges a redemption fee on shares redeemed within two months of purchase. Previously, the Vanguard funds were required to waive their redemption fees for 90 days after giving notice of an advisory change. The SEC has not generally applied this requirement to other fund companies and has now eliminated it for Vanguard. (Redemption fees—which are paid to the fund, not to Vanguard—are designed to ensure that short-term investors pay their fair share of a fund’s transaction costs.)

Glossary

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Chairman’s Letter

Dear Shareholder,

The Investor Shares of Vanguard Calvert Social Index Fund returned 10.2% and the Institutional Shares 10.3% during the fiscal year ended August 31, 2005. A large portion of the return came from technology and consumer discretionary stocks. The fund closely tracked its target index, but trailed the average return of large growth funds by more than three percentage points.

The table on page 1 presents the 12-month total return (capital change plus reinvested dividends) for your fund’s Investor Shares, along with those of its comparative standards. The table also includes the return for the fund’s lower-cost Institutional Shares, which require a minimum investment of $5 million.

You can find information on the fund’s per-share distributions during the period and its starting and ending net asset values in the table on page 6. If you hold shares of the fund in a taxable account, you may wish to review the report on after-tax returns on page 27.

Stocks staged a stealth rally during the fiscal year

During the fiscal year, the Dow Jones Wilshire 5000 Composite Index, a broad measure of U.S. stock prices, returned 15.9%, with periods of pronounced gains punctuated by stretches of weakness.

Smaller stocks outpaced their larger counterparts, and international stocks, particularly those from emerging markets, delivered outstanding returns.

As oil prices touched all-time highs, energy-related stocks were, not surprisingly, among the best performers. (It’s worth noting that, in inflation-adjusted terms, energy prices remained well below their early-1980s peaks.) Financial services and auto-industry stocks were among the weaker performers. Banks and other lenders contended with a tricky interest rate environment, while the well-publicized financial woes of the auto giants and their suppliers weighed on their share prices.

In the bond market, yields defied expectations

In the fixed income markets, short-term interest rates rose sharply while longer-term rates declined, an unusual pattern. Since June 2004, the Federal Reserve Board has steadily boosted its target for the federal funds rate in an effort to preempt inflationary pressures. During the 12 months, the yield of the 3-month U.S. Treasury bill, which closely follows the Fed’s moves, rose from 1.58% to 3.50%.

Corporate bonds outperformed government issues, and the Lehman Brothers Aggregate Bond Index, a measure of the broad investment-grade bond market, returned 4.1% for the 12 months.

Technology, consumer-oriented stocks led the fund’s performance

The Calvert Social Index Fund saw positive performance from 10 of the 11 sectors in which it was invested during the year. The sole exception was the small “other” category, which includes conglomerates that cross several business lines; these represented less than 1% of total assets on average.

The selection criteria for the Calvert Social Index have traditionally favored growth-oriented stocks in industries such as technology and health care, rather than value-oriented issues in such industries as utilities, manufacturing, and chemical production. In constructing the index, the Calvert Group of Bethesda, Maryland, uses a series of social screens to evaluate companies for inclusion. These screens assess each company in terms of workplace issues, environmental issues, product safety and impact, international operations and human rights, indigenous people’s rights, community relations, and corporate responsibility. As of August 31, the index included about 620 of the 1,000 largest U.S. companies.

During the fiscal year, the fund benefited from strong performance in the technology and consumer discretionary sectors, which together accounted for about one-third of the portfolio’s assets. Among the most notable tech performers were Intel, Apple Computer, and Microsoft. In the consumer discretionary group, Home Depot, Lowe’s, and takeover target Gillette were leading performers.

Small but important contributions also came from other sectors. These included producer durables, utilities, and “other energy,” a sector that is home to service providers for energy-related businesses. The last two profited from rising oil prices and growing power demand in a relatively strong economy, while the first simply saw a number of small gains from individual companies.

1 Fund inception.

Relatively weaker performance came from the fund’s largest sector, financial services. Disappointing results from several large index holdings, among them JPMorgan Chase and Bank of America, reined in the sector’s returns. Health care holdings were also relatively weak, as a number of sizable index constituents, most notably the beleaguered Pfizer, declined.

The timing of the fund’s inception has hurt its long-term record

Your fund was introduced near the beginning of the three-year downturn that took the U.S. stock market from its high point to unanticipated depths. As a result, the fund’s performance over its brief lifetime of slightly more than five years appears rather disappointing on an absolute basis. On a relative scale, however, the picture is brighter.

Since its May 31, 2000, inception, the fund has averaged an annual return of –3.3%. The gap between the returns of the fund and its target index is quite small, which is a credit to the indexing team in Vanguard’s Quantitative Equity Group. This tight tracking of the index has been impressive, because the Calvert Social Index does not incur operating expenses as the fund does. In comparison with its average mutual fund peer, the fund looks even better. As shown in the table on page 4, an initial investment of $10,000 in the fund would have been worth $8,379 on August 31, while a similar investment in the average peer would have resulted in $1,549 less.

Extremely low costs have been an important element in the fund’s competitiveness. A low expense ratio allows the fund to pass along a larger share of its investment returns to you, where they belong. The table on this page summarizes your fund’s costs, along with those of its peer group.

The virtues of having a plan

As we have counseled through the years, choosing and sticking with a carefully considered, balanced portfolio of stock, bond, and money market funds suited to your unique circumstances can be one of the most critical determinants of your portfolio’s long-term success. It is important that you remain comfortable and confident in the choices you make, and resist the temptation to change course in the face of short-term adversity.

Expense Ratios: ¹ Your fund compared with its peer group

Calvert Social Index Fund	0.25%	0.12%	1.51%

1 Peer-group expense ratio is derived from data provided by Lipper Inc. and captures information through year-end 2004.

As part of a “no hassle” long-term investment program, indexing can play a useful role. By design, the indexing strategy can help you to capture much of the return of the relevant target index. Over time, in fact, this seemingly modest ambition has often wound up delivering above-average performance relative to actively managed competitors. For socially conscious investors seeking the benefits of indexing, Vanguard Calvert Social Index Fund can be an important portfolio holding.

Thank you for entrusting your assets to Vanguard.

Sincerely,

John J. Brennan
Chairman and Chief Executive Officer

Fund to Adopt New Benchmark, Change Name

As part of Vanguard’s ongoing efforts to provide superior investments at the lowest reasonable cost, the fund’s board of trustees recently elected to adopt a new target index, the FTSE4Good US Select Index, for the fund. This index, which is administered by FTSE Group, is based on socially responsible criteria comparable to those of the Calvert Social Index. The change will not affect the fund’s investment objectives and strategy, nor will it substantially alter the fund’s fundamental characteristics. As part of this change, the fund will be renamed Vanguard FTSE Social Index Fund. We expect the changes to be effective in late December.

Notes to Financial Statements

Vanguard Calvert Social Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Investor Shares and Institutional Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for investors who meet certain administrative and servicing criteria and invest a minimum of $5 million.

In September 2005, the board of trustees elected to adopt a new target index, the FTSE4Good US Select Index, for the fund. This change is expected to be effective in late December.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex–dividend date.

4. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

5. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $47,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.05% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

For tax purposes, at August 31, 2005, the fund had $3,045,000 of ordinary income available for distribution. The fund had available realized losses of $16,424,000 to offset future net capital gains of $56,000 through August 31, 2009, $3,511,000 through August 31, 2010, $5,505,000 through August 31, 2011, $3,200,000 through August 31, 2012, $985,000 through August 31, 2013, and $3,167,000 through August 31, 2014.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $25,697,000, consisting of unrealized gains of $53,798,000 on securities that had risen in value since their purchase and $28,101,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $117,957,000 of investment securities and sold $42,244,000 of investment securities other than temporary cash investments.

E. The market value of securities on loan to broker/dealers at August 31, 2005, was $476,000, for which the fund received cash collateral of $517,000.

F. Capital share transactions for each class of shares were:

Report of Independent Registered Public Accounting Firm

To the Shareholders and Trustees of Vanguard Calvert Social Index Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Calvert Social Index Fund (the “Fund”) at August 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2005 by correspondence with the custodian and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

About Your Fund’s Expenses

The table below illustrates your fund’s costs in two ways:

1. Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

2. Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Six Months Ended August 31, 2005
	Beginning Account Value 2/28/2005	Ending Account Value 8/31/2005	Expenses Paid During Period¹

Based on Actual Fund Return
Investor Shares	$1,000.00	$1,033.46	$1.28
Institutional Shares	1,000.00	1,033.42	0.62

Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.95	$1.28
Institutional Shares	1,000.00	1,024.60	0.61

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.25% for Investor Shares and 0.12% for Institutional Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

You can find more information about the fund’s expenses, including annual expense ratios since inception, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

Trustees Renew Advisory Arrangement

The board of trustees of Vanguard Calvert Social Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

The board based its decisions upon its most recent evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangement. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services
The board considered the quality of the fund’s investment management over both short- and long-term periods, and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than two decades. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and oversees more than $620 billion in assets (stocks and bonds). Mr. Sauter has led the Quantitative Equity Group since 1987. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance
The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of its benchmark and peer group. The board noted that the fund has performed in line with expectations and that its results have been consistent with its investment strategy. Information about the fund’s performance, including some of the data considered by the board, can be found in the Performance Summary section of this report.

Cost
The fund’s expense ratio was far below the average expense ratio charged by funds in its peer group. The fund’s advisory expense ratio was also well below its peer-group average. Information about the fund’s expense ratio appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale
The board of trustees concluded that the fund’s low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

Glossary

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund’s equity assets represented by stocks or depositary receipts of companies based outside the United States.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

Chairman’s Letter

Dear Shareholder,

In this, the second annual report to shareholders of the Vanguard U.S. Sector Index Funds, I’m pleased to report that our offerings have continued to develop. During the 12 months ended August 31, 2005, we introduced Admiral Share classes in the consumer discretionary, energy, and telecommunication services sectors; we also added to our VIPERs lineup, launching exchange-traded shares in the energy, industrials, and telecommunications sectors.

Of the funds and share classes in operation for the full 12-month period, Vanguard Utilities VIPERs posted the highest returns (+33.1%, based on market price) and Vanguard Financials VIPERs the lowest (+6.8%, also based on market price). Those that have operated for less than 12 months produced a wider range of results. The tables on page 1 show the total returns for the funds, the broad U.S. stock market, as measured by the Morgan Stanley Capital International US Investable Market 2500 (MSCI US IMI/2500) Index, and the respective target indexes, which are subsets of the broad index.

Stocks staged a stealth rally

During the fiscal year, the Dow Jones Wilshire 5000 Composite Index, a broad measure of U.S. stock prices, returned 15.9%, with periods of pronounced gains punctuated by stretches of weakness. Smaller stocks outpaced their larger counterparts, and international stocks, particularly those from emerging markets, delivered outstanding returns.

auto-industry stocks were among the weaker performers. Banks and other lenders contended with a tricky interest rate environment, while the well-publicized financial woes of the auto giants and their suppliers weighed on their share prices.

In the bond market, yields defied expectations

In the fixed income markets, short-term interest rates rose sharply, while longer-term rates declined, an unusual pattern. Since June 2004, the Federal Reserve Board has steadily boosted its target for the federal funds rate in an effort to preempt inflationary pressures. During the 12 months, the yield of the 3-month U.S. Treasury bill, which closely follows the Fed’s moves, rose from 1.58% to 3.50%.

Energy posted the best results, but gains were widespread

With one exception, all share classes of the Vanguard U.S. Sector Index Funds posted positive results during the 2005 fiscal year. The exception, the Consumer Discretionary Index Fund’s Admiral Shares (–1.9%), began operations on July 14, 2005, less than two months before the close of the fiscal year. The Consumer Discretionary VIPERs, by contrast, existed for the full 12 months and returned 14.9%.

The various inception dates of the funds’ share classes make performance comparisons difficult, but pockets of relative strength and weakness were readily apparent. As I mentioned above, energy-related stocks enjoyed strong performance, benefiting from rising oil and gas prices. The Energy Index Fund thus provided the highest returns for the year, rising 40.3% for Admiral Shares and 48.1% for VIPER Shares (the share classes were launched on different dates during the period). The utilities sector also outperformed the market as a whole, as many gas companies advanced on the surge in energy prices. Information technology stocks were leaders as well, recording healthy returns on the strength of renewed corporate spending.

For the most part, the funds closely tracked their respective target benchmarks, consistent with their objectives. Some of the funds diverged a bit by necessity, because they are required under IRS regulations to meet certain diversification standards. This was the case for the Consumer Staples, Energy, Industrials, and Telecommunication Services Index Funds.

In general, however, the U.S. Sector Index Funds have delivered tight index tracking since early 2004, when the first funds were introduced. Although the record is short, it’s nevertheless a tribute to the talents of Vanguard Quantitative Equity Group, the investment advisor. The close tracking also underscores the value of the funds’ low costs, which reduce the inevitable gap between an index—which has no operating costs—and a real-world index mutual fund, which does. For a look at each fund’s record since inception, see the appropriate Performance Summary pages in this report.

Sector funds serve best as a portfolio’s supporting players

Like spices in a stew, the U.S. Sector Index Funds can complement the other ingredients in your investment portfolio. These funds can enhance exposure to sectors that may be underrepresented, or be used in more sophisticated strategies to moderate the risks of overexposure to particular sectors. Of course, a meal is more than spices. And wise investors know that the recipe for successful investing calls for diversification within and across asset classes. A portfolio that includes stocks, bonds, and money market funds in proportions appropriate for your risk tolerance and time horizon will help you digest periods of underperformance in individual sectors or asset classes.

Thank you for investing your assets with Vanguard.

Sincerely,

John J. Brennan
Chairman and Chief Executive Officer

Consumer Discretionary Index Fund

Notes to Financial Statements

Vanguard Consumer Discretionary Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares were first issued on July 14, 2005. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

5. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Fees assessed on redemptions of Admiral Shares are credited to paid-in capital.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $3,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.003% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended August 31, 2005, the fund realized $1,521,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

For tax purposes, at August 31, 2005, the fund had $117,000 of ordinary income available for distribution. The fund had available realized losses of $68,000 to offset future net capital gains of $36,000 through August 31, 2013, and $32,000 through August 31, 2014.

At August 31, 2005, net unrealized depreciation of investment securities for tax purposes was $57,000, consisting of unrealized gains of $1,149,000 on securities that had risen in value since their purchase and $1,206,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $33,762,000 of investment securities and sold $23,270,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

Consumer Staples Index Fund

Notes to Financial Statements

Vanguard Consumer Staples Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Fees assessed on redemptions of Admiral Shares are credited to paid-in capital.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $8,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

For tax purposes, at August 31, 2005, the fund had $512,000 of ordinary income available for distribution. The fund had available realized losses of $18,000 to offset future net capital gains through August 31, 2014.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $2,103,000, consisting of unrealized gains of $4,164,000 on securities that had risen in value since their purchase and $2,061,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $56,086,000 of investment securities and sold $2,806,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

Energy Index Fund

Notes to Financial Statements

Vanguard Energy Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares were first issued on October 7, 2004, and are available to any investor who meets the fund’s minimum purchase requirements. VIPER Shares were first issued on September 23, 2004, and first offered to the public on September 29, 2004. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

2. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $24,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the period ended August 31, 2005, the fund realized $2,452,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

For tax purposes, at August 31, 2005, the fund had $1,928,000 of ordinary income available for distribution. The fund had available realized losses of $36,000 to offset future net capital gains of $5,000 through August 31, 2013, and $31,000 through August 31, 2014.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $41,256,000, consisting of unrealized gains of $41,388,000 on securities that had risen in value since their purchase and $132,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended August 31, 2005, the fund purchased $230,709,000 of investment securities and sold $33,127,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

	September 23, 2004¹ to August 31, 2005

Financials Index Fund

Notes to Financial Statements

Vanguard Financials Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $5,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

For tax purposes, at August 31, 2005, the fund had $281,000 of ordinary income available for distribution. The fund had available realized losses of $92,000 to offset future net capital gains through August 31, 2014.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $292,000, consisting of unrealized gains of $2,106,000 on securities that had risen in value since their purchase and $1,814,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $36,003,000 of investment securities and sold $1,861,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

Health Care Index Fund

Notes to Financial Statements

Vanguard Health Care Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $31,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.03% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

For tax purposes, at August 31, 2005, the fund had $1,579,000 of ordinary income available for distribution. The fund had available realized losses of $104,000 to offset future net capital gains through August 31, 2014.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $15,766,000, consisting of unrealized gains of $24,382,000 on securities that had risen in value since their purchase and $8,616,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $243,310,000 of investment securities and sold $12,609,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

Industrials Index Fund

Notes to Financial Statements

Vanguard Industrials Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. The fund has not issued any Admiral Shares through August 31, 2005. VIPER Shares were first issued on September 23, 2004, and first offered to the public on September 29, 2004. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $1,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.001% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

During the period ended August 31, 2005, the fund realized $1,611,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

The fund used a tax accounting practice to treat a portion of the price of capital shares redeemed during the year as distributions from realized capital gains. Accordingly, the fund has reclassified $18,000 from accumulated net realized gains to paid-in capital.

For tax purposes, at August 31, 2005, the fund had $103,000 of ordinary income available for distribution. At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $351,000, consisting of unrealized gains of $594,000 on securities that had risen in value since their purchase and $243,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended August 31, 2005, the fund purchased $31,896,000 of investment securities and sold $17,584,000 of investment securities, other than temporary cash investments.

E. Capital share transactions were (see table below):

Materials Index Fund

Notes to Financial Statements

Vanguard Materials Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $7,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes. During the year ended August 31, 2005, the fund realized $4,300,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

The fund used a tax accounting practice to treat a portion of the price of capital shares redeemed during the year as distributions from realized capital gains. Accordingly, the fund has reclassified $39,000 from accumulated net realized gains to paid-in capital.

For tax purposes, at August 31, 2005, the fund had $542,000 of ordinary income available for distribution. At August 31, 2005, net unrealized depreciation of investment securities for tax purposes was $4,215,000, consisting of unrealized gains of $583,000 on securities that had risen in value since their purchase and $4,798,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $74,502,000 of investment securities and sold $38,194,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

Telecommunication Services Index Fund

Notes to Financial Statements

Vanguard Telecommunication Services Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares were first issued on March 11, 2005, and are available to any investor who meets the fund's minimum purchase requirements. VIPER Shares were first issued on September 23, 2004, and first offered to the public on September 29, 2004. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

2. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $2,000 to Vanguard (included in Other Assets), representing 0.01% of the fund's net assets and 0.002% of Vanguard's capitalization. The fund's trustees and officers are also directors and officers of Vanguard.

During the period ended August 31, 2005, the fund realized $2,413,000 of net capital gains resulting from in-kind redemptions-in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

The fund used a tax accounting practice to treat a portion of the price of capital shares redeemed during the year as distributions from realized capital gains. Accordingly, the fund has reclassified $212,000 from accumulated net realized gains to paid-in capital.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $443,000, consisting of unrealized gains of $1,531,000 on securities that had risen in value since their purchase and $1,088,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended August 31, 2005, the fund purchased $48,334,000 of investment securities and sold $34,370,000 of investment securities, other than temporary cash investments.

E. Capital share transactions for each class of shares were (see table below):

Utilities Index Fund

Notes to Financial Statements

Vanguard Utilities Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Admiral Shares and VIPER Shares. Admiral Shares are available to any investor who meets the fund’s minimum purchase requirements. VIPER Shares are listed for trading on the American Stock Exchange; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At August 31, 2005, the fund had contributed capital of $11,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes. During the year ended August 31, 2005, the fund realized $4,899,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

For tax purposes, at August 31, 2005, the fund had $638,000 of ordinary income available for distribution. The fund had available realized losses of $69,000 to offset future net capital gains of $62,000 through August 31, 2013 and $7,000 through August 31, 2014.

At August 31, 2005, net unrealized appreciation of investment securities for tax purposes was $11,686,000, consisting of unrealized gains of $12,028,000 on securities that had risen in value since their purchase and $342,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended August 31, 2005, the fund purchased $95,685,000 of investment securities and sold $29,087,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker/dealers at August 31, 2005, was $154,000, for which the fund received cash collateral of $200,000.

F. Capital share transactions for each class of shares were (see table below):

Report of Independent Registered Public Accounting Firm

To the Shareholders and Trustees of Vanguard Consumer Discretionary Index Fund, Vanguard Consumer Staples Index Fund, Vanguard Energy Index Fund, Vanguard Financials Index Fund, Vanguard Heath Care Index Fund, Vanguard Industrials Index Fund, Vanguard Information Technology Index Fund, Vanguard Materials Index Fund, Vanguard Telecommunication Services Index Fund and Vanguard Utilities Index Fund:

In our opinion, the accompanying statements of net assets, statements of assets and liabilities and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Consumer Discretionary Index Fund, Vanguard Consumer Staples Index Fund, Vanguard Energy Index Fund, Vanguard Financials Index Fund, Vanguard Health Care Index Fund, Vanguard Industrials Index Fund, Vanguard Information Technology Index Fund, Vanguard Materials Index Fund, Vanguard Telecommunication Services Index Fund and Vanguard Utilities Index Fund (the “Funds”) at August 31, 2005, and the results of each of their operations, the changes in each of their net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2005 by correspondence with the custodian and by agreement to the underlying ownership records for Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2005 tax information (unaudited) for Vanguard U.S. Sector Index Funds

This information for the fiscal year ended August 31, 2005, is included pursuant to provisions of the Internal Revenue Code. The funds distributed qualified dividend income to shareholders during the fiscal year as follows:

Index Fund	Qualified Dividend Income ($000)


Consumer Discretionary	105

Energy	132

Financials	696

Health Care	315

Industrials	64

Information Technology	250

Materials	401

Telecommunication Services	123

Utilities	2,405

For corporate shareholders, the percentage of investment income (dividend income plus short-term gains, if any) that qualifies for the dividends-received
deduction is as follows:

Your Fund’s After-Tax Returns

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect the reduced tax rates on ordinary income (including qualified dividend income) and short-term capital gains that became effective as of January 1, 2003, and on long-term capital gains realized on or after May 6, 2003. To calculate qualified dividend income, we use actual prior-year figures and estimates for 2005. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.) The table shows returns for VIPER Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes. Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

About Your Fund’s Expenses

1. Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only; they do not include the 2% fee assessed on redemptions of Admiral Shares held for less than one year. If the fee were applied to your account, your costs would be higher. The funds do not carry a “sales load.” The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions. You can find more information about the fund’s expenses in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

1 The table does not include data for funds or share classes of funds with fewer than six months of history.
2 The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: 0.25% for the Consumer Discretionary Index Fund VIPER Shares; 0.28% for the Consumer Staples Index Fund Admiral Shares and 0.25% for the VIPER Shares; 0.28% for the Energy Index Fund Admiral Shares and 0.25% for the VIPER Shares; 0.28% for the Financials Index Fund Admiral Shares and 0.25% for the VIPER Shares; 0.28% for the Health Care Index Fund Admiral Shares and 0.25% for the VIPER Shares; 0.25% for the Industrials Index VIPER Shares; 0.28% for the Information Technology Index Fund Admiral Shares and 0.25% for the VIPER Shares; 0.28% for the Materials Index Fund Admiral Shares and 0.25% for the VIPER Shares; 0.25% for the Telecommunication Services Index VIPER Shares; 0.28% for the Utilities Index Fund Admiral Shares and 0.25% for the VIPER Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Renew Advisory Arrangement

The board of trustees of the Vanguard U.S. Sector Index Funds has renewed the funds’ investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the funds. The board determined that continuing the funds’ internalized management structure was in the best interests of the funds and their shareholders.

The board based its decision upon its most recent evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the agreement. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services

The board considered the quality of the funds’ investment management over both short- and long-term periods and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than two decades. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and oversees more than $620 billion in assets (stocks and bonds). Mr. Sauter has led the Quantitative Equity Group since 1987. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth. The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance

The board considered the short- and long-term performance of the funds, including any periods of outperformance or underperformance of relevant benchmarks and peer groups. The board noted that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ performance, including some of the data considered by the board, can be found in the Performance Summary pages of this report.

Cost

The funds’ expense ratios were far below the average expense ratios charged by funds in their respective peer groups. The funds’ advisory expense ratios were also well below their peer-group averages. Information about the funds’ expense ratios appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements sections.

The benefit of economies of scale

The board of trustees concluded that the funds’ low-cost arrangement with Vanguard ensures that the funds will realize economies of scale as they grow, with the cost to shareholders declining as fund assets increase. The board will consider whether to renew the advisory arrangement again after a one-year period.

Glossary

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund. Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund’s equity assets represented by stocks or depositary receipts of companies based outside the United States.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.
