                            LETTER FROM THE CHAIRMAN

FELLOW SHAREHOLDER,

After two painful  fiscal years,  Vanguard U.S.  Growth Fund's  Investor  Shares
returned  8.7% (9% for Admiral  Shares)  during the fiscal year ended August 31,
2003.  While the rebound was welcome,  the result lagged the 12.5% return of the
average  large-capitalization  growth  mutual  fund  and the  14.1%  gain of the
Russell 1000 Growth Index, a benchmark for the U.S. large-cap universe.

The fund benefited from a stock market environment that brightened  considerably
with the onset of spring.  While some of the fund's holdings  recorded  outsized
gains, the fund's investments  collectively  didn't keep pace with the large-cap
segment of the market.  The table on this page provides  details about the total
return  (capital  change  plus  reinvested  distributions)  for the fund and its
peers, its unmanaged benchmark,  and the index that tracks the entire U.S. stock
market.


DISMAL AT THE START, THE OVERALL STOCK MARKET EVENTUALLY PERKED UP

A slumping economy,  weak corporate profits, and growing  geopolitical  tensions
weighed  heavily on the stock  market last fall as our fiscal year began,  and a
two-month rally from mid-October  quickly ran out of steam.  However,  following
the  successful  conclusion  of major  combat  operations  in Iraq, a distinctly
upbeat mood  permeated  the  marketplace.  Stock prices began to rebound  across
capitalizations  and industry  sectors in response to solid  corporate  earnings
reports and a slew of positive economic reports.

                                       1


The U.S.  stock  market,  as measured by the Wilshire  5000 Total Market  Index,
returned 14.9% for the fiscal year. Technology and other growth-oriented stocks,
which had sustained  massive  losses  during the past few years,  were among the
most  impressive  gainers.  The market's  smaller stocks outpaced larger issues,
demonstrating investors' renewed appetite for risk.

ADMIRAL(TM) SHARES

A lower-cost  class of shares  available to many  longtime  shareholders  and to
those with significant investments in the fund.
- --------------------------------------------------------------------------------

U.S. investors were rewarded with good returns in many international  markets as
well,  although stock  performance was only part of the story.  The weakening of
the U.S. dollar by almost 10% relative to the euro transformed results that were
mediocre by  local-currency  standards into strong  dollar-denominated  returns.

INTEREST RATES FELL THROUGH MUCH OF THE YEAR, THEN BOUNCED BACK

In the bond  market,  the  fiscal  year was marked by two  distinctly  different
phases.  Prior to  mid-June,  the  lethargic  economy  and  ongoing  flight from
equities to bonds drove the prices of bonds higher and their yields  lower.  The
yield of the  benchmark  10-year U.S.  Treasury note dropped to a 45-year low of
3.11% on June 13. After that point,  however,  longer-term  interest  rates rose
rapidly,  with the yield of the 10-year  T-note  standing at 4.46% on August 31.
For the 12 months,  the Lehman  Brothers  Aggregate Bond Index, a measure of the
taxable investment-grade bond market, provided a total return of 4.4%.

Corporate  bonds  outperformed  Treasuries  across  all  maturities.  High-yield

tracks the  performance  of bonds issued by companies  with low credit  ratings,
returned 24.9% for the year.

                                       2



Short-term  interest  rates  generally  declined  for the 12  months,  but  rose
somewhat toward the end. In an effort to add fuel to the economic recovery,  the
Federal  Reserve  Board  trimmed  its  target  for the  federal  funds  rate two
times--in  November  2002 and June  2003-- by a total of 75 basis  points  (0.75
percentage point).  The rate stood at 1.00% at the fiscal year-end.  The 3-month
U.S.  Treasury  bill,  which  typically  lags Fed moves,  began the fiscal  year
yielding  1.67% and closed at 0.97% after  falling as low as 0.81% in  mid-June.

AFTER A POOR SHOWING IN THE FIRST SIX MONTHS, THE FUND REBOUNDED

The U.S.  Growth Fund struggled  during the first half of its fiscal year as the
undertow exerted by the  still-declining  stock market and poor stock selections
pulled  performance  under.  Fortunately,  the second half of the period brought
welcome relief from a historic bear market.  The fund's technology  holdings led
the way,  rising 33.5%,  accounting  for about  two-thirds of the fund's advance
over the past 12 months.

Also adding buoyancy were the fund's financial service selections. As investment
sentiment  improved and activity in the capital  markets  increased,  the fund's
investments  in familiar  names such as  Citigroup  and  Merrill  Lynch paid off
handsomely. These and other successful selections enabled the fund to outperform
the financial services stocks in the Russell 1000 Growth Index.

In  the  utilities  sector,  overweighted  considerably  by the  fund's  advisor
relative to the Russell 1000 Growth Index,  the U.S.  Growth Fund benefited from
holding two of the larger cable TV providers.

POOR PERFORMANCE IN A FEW SECTORS HELD RETURNS BACK

Unfortunately,  U.S. Growth's holdings in other industry groups  underperformed,
causing  the  fund's  one-year  return  to  trail  its  benchmark.  The  biggest
disappointments were among health care holdings.  These stocks, which on average
represented the fund's largest sector weighting,  declined -3.2%,  substantially
trailing the 6.6% performance of that sector in the benchmark.

The  performance of fund holdings in the consumer  staples  (-3.2%) and consumer
discretionary (13.1%) sectors were also lackluster.

                                       3




THE RISKS AND REWARDS OF THE FUND'S APPROACH

At the  close of its  fiscal  year,  your fund  held a  relatively  concentrated
portfolio of 58 stocks.  The U.S.  Growth  Fund's  strategy is to seek  superior
performance by investing in 45 to 65 large,  established  companies  believed by
its investment  advisor to have the best prospects for strong growth.  On August
31, the top ten holdings made up 37% of assets--evidence that the fund will take
sizable  positions  in the stocks of just a handful of  companies.  This kind of
investment  approach inevitably leads at times to ups and downs that are steeper
than those of the broad market's.  The goal, of course,  is to have the ups more
than offset the downs.  As we close our second  full  fiscal year with  Alliance
Capital Management as our advisor, we haven't accomplished that goal.

- -------------------------------------------------------------------

Of course,  we believe that performance over long periods is the best measure of
any fund.  Vanguard  U.S.  Growth Fund has  struggled  during the bear market in
stocks and subsequently.  The fund's ten-year average annual return of 5% trails
both the average  large-cap  fund and the Russell  1000 Growth  Index by several
percentage  points, as shown in the accompanying  table. Also  disappointing are
the results of a hypothetical  $10,000 investment made ten years ago. The fund's
shortfall  is largely the result of its  performance  in the previous two fiscal
years, when it experienced the steepest two-year decline in its 44-year history.


THE FUND'S MANAGEMENT TEAM HAS EXPERIENCE NAVIGATING THE MARKET

Despite  the  substandard  results of recent  years,  we remain  confident  that
Vanguard U.S. Growth Fund's investment  management team, which has been in place
for just over two years, will ultimately serve  shareholders well. The people at
Alliance  Capital  Management  overseeing  the fund's  assets have  considerable
experience  in both  bull  and  bear  markets  and have  compiled  an  excellent
long-term record using the same strategy that is used in your fund.

Besides  seasoned  investment  professionals,  your fund  features  an  enduring
advantage in the form of its low costs. The expense ratio (annual

                                       4



operating  costs as a percentage  of average net assets) of the Investor  Shares
was 0.55% for the fiscal year, or $5.50 per $1,000 in assets, which is just over
one-third the 1.57% ($15.70 per $1,000) charged by the average  large-cap growth
fund in 2002  (according to Lipper  Inc.).  This  substantial  cost savings will
almost certainly compound to your financial advantage over time.

DIVERSIFICATION REMAINS KEY

Because  Vanguard U.S.  Growth Fund focuses on large-cap  stocks and is somewhat
aggressive  in its  pursuit  of  capital  appreciation,  we like to  remind  our
shareholders   that  the  fund  is  appropriate  as  just  one  component  of  a
well-diversified portfolio.  Sticking with a broad mix of stock, bond, and money
market  investments  that  matches  your goals and risk  tolerance  will  always
provide  the best  chance  for  success  over the long  haul,  no matter how the
market--or any single fund--performs in the short term.

We deeply appreciate your continued  confidence and look forward to reporting to
you in six months.

Sincerely,

REPORT FROM THE ADVISOR

For the 12-month  period ended August 31, 2003, the Investor  Shares of the U.S.
Growth Fund  advanced 8.7% while our  benchmark,  the Russell 1000 Growth Index,
rose 14.1%.  Market volatility  remained  exceptionally  high during the period,
with  investor  confidence  vacillating  on  perceptions  of  risks  in Iraq and
evolving  business  fundamentals.  The  underperformance  of our  portfolio is a
product  of our  unwillingness  to  chase  these  extremes  in  investors'  risk
tolerance.

Frankly,  we were  insufficiently  defensive during the period of maximum stress
that preceded  mid-March 2003. We were  characteristically  underweighted in the
slower-growing,  stable consumer staples stocks whose  valuations  soared in the
face of immense  risk-aversion.  That risk-aversion vanished dramatically as the
Iraq war unfolded,  predictably  benefiting  the most  volatile and  speculative
stocks, which became the best performers over the last 51/2 months of the fiscal
year. Adherence to our discipline of owning quality growth companies kept us out
of these stocks, resulting in further underperformance.  However, the developing
trend of  improvement  in corporate  earnings  should  benefit our  positions in
attractively valued, fundamentally strong companies.

- --------------------------------------------------------------------------------
INVESTMENT PHILOSOPHY

The advisor believes that superior long-term  investment results can be achieved
by  emphasizing  investments  in  growth  companies  that are  leaders  in their
industries and that have a strong market presense.
- --------------------------------------------------------------------------------

INVESTMENT ENVIRONMENT

After a  protracted  decline over the past several  years,  investor  confidence
finally  began  to  strengthen  on  news of  general  success  in  Iraq  and the
continuing economic and corporate recovery.  Risk-aversion  declined materially,
producing a strong relative price recovery in the market's more volatile stocks.
For the 12 months ended August 31,  stocks with betas (a measure of  volatility)
above   1.3--which   account   for  27%  of  the  Russell   1000

                                       6



Growth Index benchmark--returned 39% on a capitalization-weighted  basis, versus
14.1% for the benchmark as a whole. The beta of our portfolio averaged about 1.1
over this time frame, consistent with its long-term average.  Similarly,  stocks
with market  capitalizations  below $8 billion (a 15%  weighting  in the Russell
1000 Growth Index) returned 36%, while those with market caps above $115 billion
(29% of the  index),  returned  4%. Our  portfolio's  median  market cap was $61
billion as of August 31.

OUR SUCCESSES

Top  contributors  to the fund's return included  several  leading  companies in
technology,  financial  services,  and health care. Good performers in financial
services,  including  Citigroup and Merrill Lynch,  provided a boost that offset
our overweighted position in the financial services sector, which underperformed
the  market.  Veritas  Software,  our  leading  contributor,  added  nearly  1.8
percentage points to relative performance. Veritas continues to lead the storage
software  market and remains a significant  fund holding.  Juniper  Networks and
Altera  were also  solid tech  contributors.  In health  care,  Amgen has posted
strong operating results and stock performance.  In the cable industry,  Comcast
and Cox Communications did well for us. These companies' new services, including
broadband  and  digital  video,  are  supporting  solid  revenue  and  growth in
operating cash flow.

OUR SHORTFALLS

Poor stock  selection  in the  underperforming  health care sector was the major
detractor to our relative  performance in the fiscal year. Our holdings in Tenet
Healthcare,  Cardinal Health,  and Wyeth cost the fund about 3 percentage points
in relative performance.  (Tenet and Cardinal Health have produced disappointing
operating results, and we have now sold them both.)

The  fund  was  underweighted  in  the  consumer   discretionary  sector,  which
outperformed  during the period. Our holdings in Kohl's and Home Depot detracted
more than 2 percentage  points from  relative  performance.  Home Depot has been
replaced  in the  portfolio  by Lowe's,  which  continues  to grow faster and to
execute successfully in the current competitive environment. We have reduced our
exposure to Kohl's,  but it remains a significant  holding.

POSITIONING OF THE PORTFOLIO

The foundation is in place for a rebound in the nation's  economic growth and in
corporate  profits.  Many of the structural  excesses that developed  during the
expansion   of  the  1990s   have  been   corrected,   and

                                       7




restructuring  and  recapitalization  have  improved   corporations'   operating
efficiency.  Inventory  levels  are low,  suggesting  potential  for a pickup in
manufacturing with any improvement in consumption.

Despite  subdued  revenue  growth  and  pricing  power,  corporate  profits  and
productivity have been impressive: Profits have now expanded for six consecutive
quarters,   and  free  cash  flow  is  currently  at  record   levels.   Capital
spending--which  appears  particularly  depressed  relative to  depreciation--is
exhibiting tentative signs of recovery from the most severe cyclical contraction
in 50 years.  The U.S.  banking  system has emerged from three very  challenging
years with capital  ratios,  asset  quality,  profitability,  and  liquidity all
comparing impressively with prior recessionary periods.  Recent months have seen
encouraging trends in consumer,  corporate,  and investor confidence alike. Last
but not least, liquidity appears ample, and federal monetary and fiscal policies
remain stimulative.

We are positioning the portfolio to benefit from a continuing cyclical recovery,
but we are  maintaining  our  discipline  regarding  valuation.  Thus,  we  have
selectively built positions in leading technology companies, but have not chased
companies  whose  recovery  appears to be fully  reflected in their stock prices
already.  Instead, we are finding many leading companies in the consumer, health
care, and financial services sectors whose valuations are very attractive.

Importantly, we have concentrated the portfolio in companies that are successful
and, in many cases, dominant across sectors. These companies have certainly been
stress-tested over the past few years, yet they have maintained superior balance
sheets,  cash flows,  sales, and earnings growth. We believe companies that have
executed  successfully  throughout the  challenging  environment of recent years
will be outperformers in the period ahead.

These stocks,  among the fund's largest  positions,  include Pfizer,  Amgen, and
Johnson & Johnson in health care;  Wal-Mart and Procter & Gamble among  consumer
companies; AIG and Citigroup in finance; and Microsoft, Intel, Dell, and Veritas
Software in technology.

The overall  historical  earnings growth of the stocks in our portfolio compares
favorably with that of the broad market, reflecting their fundamental strength.

While  we have  been  disappointed  with  recent  relative  performance,  we are
encouraged by the strong fundamentals of our holdings,  which have

                                       8




in many cases exceeded expectations. We believe such fundamental success will be
reflected in relative valuation and superior performance.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation to the ups and downs of the fund's  target  index or an overall  market
index.  Each 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 benchmark,  and the less
reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
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 American 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 the fund's  target index
or by an  overall  market  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.
- --------------------------------------------------------------------------------
TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------
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
dividends paid on stocks in the index.

PERFORMANCE SUMMARY                                              AS OF 8/31/2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

This table  presents  average annual total returns  through the latest  calendar
quarter--rather  than  through  the end of the  fiscal  period.  Securities  and
Exchange Commission rules require that we provide this information.

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 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. However,  they do not reflect the reduced rates on "qualified
dividend income."

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 indicate how it will perform in the future.

ABOUT YOUR FUND EXPENSES

All mutual funds have  operating  expenses.  These  expenses  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 net assets.  This figure is known
as the expense ratio.

A HYPOTHETICAL EXAMPLE

We believe it is  important  for you to  understand  the impact of costs on your
investment.  The following  example  illustrates  the costs that you would incur
over a 12-month  period if you  invested  $10,000 in the fund,  using the fund's
actual return and operating  expenses for the fiscal year ended August 31, 2003.
For comparative  purposes, we also list the average expense ratio for the fund's
peer group, which is derived from data provided by Lipper Inc.

The funds do not charge transaction fees; these results apply whether or not you
redeemed your  investment at the end of the given period.  Your actual costs may
have been higher or lower,  depending on the amount of your  investment and your
holding period. Peer-group ratios capture data through year-end 2002.


You can find more  information  about a fund's expense ratio,  including  annual
expense ratios for the past five years, in the Financial  Statements  section of
this  report.  For  additional  information  on  operating  expenses  and  other
shareholder  costs,  please  refer  to the  fund's  prospectus.  The  prospectus
presents  hypothetical  shareholder costs over various time periods based upon a
$10,000 investment and a return of 5% a year. This standardized  example,  which
appears in all mutual fund  prospectuses,  may be useful to you in comparing the
costs of investing in different funds.

FINANCIAL STATEMENTS                                             AS OF 8/13/2003

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments to calculate the fund's Net Assets.  Finally, Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets,  you will find a table displaying the
composition of the fund's net assets.  Because all income and any realized gains
must be distributed to  shareholders  each year, the bulk of net assets consists
of Paid-in  Capital  (money  invested by  shareholders).  The amounts  shown for
Undistributed  Net Investment  Income and Accumulated Net Realized Gains usually
approximate  the sums the fund had available to distribute  to  shareholders  as
income  dividends  or capital  gains as of the  statement  date,  but may differ
because  certain  investments or  transactions  may be treated  differently  for
financial  statement and tax purposes.  Any Accumulated Net Realized Losses, and
any cumulative  excess of  distributions  over net income or net realized gains,
will appear as negative balances.  Unrealized Appreciation (Depreciation) is the
difference  between the market value of the fund's  investments  and their cost,
and reflects the gains  (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the net amount shareholders invested in
or redeemed  from the fund.  Distributions  and Capital Share  Transactions  are
shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

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.  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.  REPURCHASE  AGREEMENTS:  The fund,  along  with  other  members  of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.

     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. OTHER:  Dividend  income is recorded on the ex-dividend  date.  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),  shareholder  reporting,  and  proxies.  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. provides investment advisory services to the
fund for a fee  calculated at an annual  percentage  rate of average net assets.
The  basic  fee  is  subject  to  quarterly  adjustments  based  on  the  fund's
performance relative to the Russell 1000 Growth Index. For the year ended August
31, 2003, the investment advisory fee represented an effective annual basic rate
of 0.14% of the fund's  average  net  assets  before a  decrease  of  $1,362,000
(0.02%) based on performance.

                                       22


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, 2003, the fund had contributed capital of $1,178,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 1.18% of  Vanguard's  capitalization.  The fund's  trustees and officers are
also directors and officers of Vanguard.

D. The fund has asked its investment  advisor 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, 2003,  these  arrangements  reduced  expenses by $3,086,000 (an
annual rate of 0.05% 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 will reverse when the  securities  are sold.  The fund realized
gains on the sale of these securities  through August 31, 2002, and subsequently
during the year  ended  August  31,  2003,  of  $347,099,000  and  $309,008,000,
respectively,  for financial statement  purposes,  which were included in fiscal
2001  mark-to-market  gains  for  tax  purposes.  The  remaining  difference  of
$256,384,000 is reflected in the balance of accumulated net realized losses; the
corresponding  difference between the securities' costs for financial  statement
purposes and for tax purposes is reflected in unrealized depreciation.

For tax  purposes,  at August 31,  2003,  the fund had  $17,037,000  of ordinary
income  available for  distribution.  The fund had available  realized losses of
$7,087,673,000  to offset  future net capital  gains of  $3,610,329,000  through
August 31,  2010,  $2,548,333,000  through  August 31,  2011,  and  $929,011,000
through August 31, 2012.

At August 31, 2003, net unrealized depreciation of investment securities for tax
purposes was  $403,593,000,  consisting of unrealized  gains of  $444,713,000 on
securities  that had risen in value since their  purchase  and  $848,306,000  in
unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended August 31, 2003, the fund purchased  $2,954,500,000  of
investment  securities and sold  $3,040,533,000  of investment  securities other
than temporary cash investments.

G. The market value of securities on loan to  broker/dealers at August 31, 2003,
was  $10,620,000,  for which the fund held cash collateral of  $10,989,000.  The
fund invests cash collateral  received in repurchase  agreements,  and records a
liability for the return of the collateral, during the period the securities are
on loan.

REPORT OF INDEPENDENT AUDITORS

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, 2003,  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  five  years  in the  period  then  ended,  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 auditing
standards generally accepted in the United States of America, which 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, 2003 by correspondence with the custodian, provide a
reasonable basis for our opinion.

CAPITALIZE ON YOUR IRA

Are you taking full advantage of your individual  retirement account? You really
should be. The contribution  limits on IRAs were recently  raised,  making these
tax-deferred accounts more powerful options for retirement savers.

Here's how you can exploit  your  IRA--and  improve  your  chances of having the
retirement of your dreams.

CONTRIBUTE THE MAXIMUM AMOUNT EACH YEAR.

It may be an  obvious  point,  but if you  invest as much in your IRA as the law
allows--currently  $3,000 per tax year if you are under age 50 and $3,500 if you
are age 50 or over--you will increase the odds of meeting your retirement goals.
"Max out" every year you can.

MAKE IT AUTOMATIC.

Put your IRA on autopilot by taking advantage of Vanguard's Automatic Investment
Plan.  Your IRA  contributions  will be  deducted  from your bank  account  on a
schedule of your choosing, making retirement investing a healthy habit.

CONSIDER COST.

The owners of low-cost  investments keep a larger portion of their gross returns
than the owners of high-cost investments.  Over the long term, avoiding costlier
mutual funds and brokerage commissions could significantly boost your retirement
savings. Our low costs are one reason a Vanguard IRA(R) is such a smart choice.

into your IRA.

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

LETTER FROM THE CHAIRMAN

Fellow Shareholder,

Vanguard International Growth Fund's performance during its 2003 fiscal year was
similar to that of the world  equity  markets--poor  early on but  exceptionally
strong in the second half, benefiting from a surge in early spring that affected
stock markets around the globe.

As shown in the adjacent  table,  the 9.6% return of the fund's  Investor Shares
(+9.8%  for its  Admiral  Shares)  was  well  ahead  of the  average  result  of
international  mutual funds.  Among the factors that  contributed  to the fund's
success during the 12 months ended August 31 were the strong returns in emerging
markets,  the solid gains in some  retailing and technology  companies,  and our
main investment advisor's excellent management of currency fluctuations.

DISMAL AT THE START, WORLD STOCK MARKETS PERKED UP

In the year ended August 31, 2003, the returns of stock markets across the globe
bounced up and down  during the first  several  months,  sunk early in  calendar
2003, and then stormed ahead beginning in early spring.

1


Slumping economies,  weak corporate profits, and growing  geopolitical  tensions
weighed  heavily on world  stock  markets at the onset of the  period.  However,
following the successful  conclusion of major combat  operations in Iraq, a more
upbeat mood began to permeate the marketplace.  Stock prices began to rebound as
corporate  earnings  reports  improved  and the U.S.  economy  showed signs of a
recovery.

- --------------------------------------------------------------------------------

U.S.  investors were rewarded with good returns in many  international  markets,
although stock performance was only part of the story. The weakening of the U.S.
dollar by almost  10%  relative  to the euro and the  Japanese  yen  transformed
results   that  were   mediocre   by   local-currency   standards   into  strong
dollar-denominated returns.

The U.S.  stock  market,  as measured by the Wilshire  5000 Total Market  Index,
returned 14.9% for the fiscal year. Technology and other growth-oriented stocks,
which had sustained  massive  losses  during the past few years,  were among the
most  impressive  gainers.  The market's  smaller stocks outpaced larger issues,
demonstrating investors' renewed appetite for risk.

In the fixed income arena, the theme was low--and  declining--interest rates. In
Europe, both the Bank of England and the European Central Bank cut their targets
for  short-term  interest  rates  during the period.  At the end of August,  the
European Central Bank's target for short-term rates (the minimum bid rate on the
main  refinancing  operations)  stood at 2.0%, and the Bank of England's  target
(the repo rate) stood at 3.5%. The U.S. Federal Reserve Board lowered its target
for the  federal  funds rate (the  interest  rate  charged for

2


overnight  loans between banks) to 1.0%, its lowest level in 45 years.  The Bank
of Japan's  target for  short-term  interest  rates (the  discount  rate, or the
interest  rate on the bank's loans to other banks)  remained a nearly  invisible
0.1%.

STRONG SECOND HALF RESULTED IN SOLID FISCAL-YEAR RETURNS

Vanguard International Growth Fund's fiscal-year return of 9.6% for its Investor
Shares reflects a remarkable  turnaround from its dismal start. During the first
six months of the period,  the fund returned  -11.0%.  However,  from the end of
February through August 31, the fund's return was a remarkable 23.2%.

Broadly,  the fund  benefited  from a stock  market  surge that kicked in during
early spring. Many markets in Europe and the Pacific region followed the lead of
the United States,  where positive economic signals and strengthening  corporate
profits led to a stock market upswing.

*This cash is invested by The Vanguard Group in equity
 index products to simulate investment in stocks; each
 advisor also may maintain a modest cash position.

Specifically,  the fund's commitment to emerging  markets,  which averaged about
15% of assets  during the period,  helped  performance,  as did the  decision by
Schroder  Investment  Management North America,  our main advisor,  to hedge its
exposure to the Japanese yen.  (Schroder  shifted from yen to euros,  protecting
the portfolio against the yen's decline.)

Japanese stocks, as a group, suffered during most of the period but recovered in
the summer, aiding performance. In terms of broad industry groups, our advisors'
selections  among retailers and technology  companies helped most during the six
months. Vodafone Group made a strong advance, and drug company AstraZeneca Group
and  home-improvement  retailer Kingfisher  registered big gains.  Finally,  the
fund's  underweighted  position in energy stocks boosted performance relative to
the average peer and broad international stock indexes.

On the negative side,  insurance  giant ING Groep,  which one year ago accounted
for nearly 6% of fund assets,  struggled  mightily and has since been eliminated
from the portfolio.

See  the  Advisor's  Report  on  page  7  for  more  details  about  the  fund's
performance.

Since early  February,  the fund's  assets have been  managed by two  investment
advisors,  who  independently  select  securities  for the fund. The addition of
Baillie Gifford Overseas Ltd. does not change the fund's  investment  objective.
Schroder,  which currently manages more than three-quarters of the International
Growth Fund's  assets,  has served as  investment  advisor to the fund since its
inception in 1981. The table on page 3 provides a breakdown of the fund's assets
managed by each advisor.

SOLID 2003 ADDS TO FUND'S DISTINGUISHED HISTORY

The fund's strong  performance during the past 12 months--both in absolute terms
and relative to competing  funds--was  consistent  with its excellent  long-term
results. The adjacent table shows that over the ten years ended August 31, 2003,
Vanguard  International  Growth  Fund  returned  an  annualized  5.0%,  nearly 2
percentage  points ahead of the average  return of  international  mutual funds.
This  impressive  margin  led to a  significant  difference  in wealth  over the
decade. A hypothetical  $10,000 invested in Vanguard  International  Growth Fund
would  have  grown  to more  than  $16,000  in the  ten-year  period.  The  same
investment in the average competitor would have increased to about $13,600.

As you may know, the fund's ten-year performance record is made up of periods of
both terrific gains and disappointing  declines.  Vanguard  International Growth
Fund's  long-term  success  is  testament  to the  power  of a sound  investment
strategy  applied during good markets and bad.  Throughout  the fund's  history,
shareholders  have  benefited  not only  from the  fund's  excellent  investment
management  but  also  from  its  low  operating   costs.   In  2003,   Vanguard
International  Growth Fund's operating expenses amounted to 0.69% of average net
assets for the  Investor  Shares and 0.51% for the Admiral  Shares.  The average
competitor's expenses consumed a full 1.70% of average net assets.

Because  expenses  directly  reduce  the return  that  investors  receive,  this
difference  works to the  advantage  of our  shareholders  year after year,  and
especially over the long run.

TIMELESS PRINCIPLES AMID PERSISTENT CHANGE

Since early 2000, the financial markets have followed trajectories unfamiliar to
most market participants. Stocks endured one of the longest and deepest declines
in financial  history,  while the yields of fixed income  securities  dropped to
levels not seen in a generation.  In recent months,  though,  the cycles seem to
have turned: Many stocks have produced  exceptional  returns, and interest rates
have begun to rise.

These events are no more than extreme  manifestations  of the  uncertainty  that
always  rules the  financial  markets.  At  Vanguard,  we believe  that the best
approach to this  uncertainty  is  faithful  use of the  time-tested  investment
principles:  balance,  diversification,  and low costs.  A balance among stocks,
bonds,  and money  market  funds  allows you to pursue  growth of capital  while
securing some protection from the markets'  inevitable  downturns.  In any asset
mix, low costs are key to ensuring that you reap the maximum  possible  share of
the financial markets' rewards.

Vanguard  International Growth Fund can be an important component of your equity
allocation,  providing  exposure to markets  outside of the United States and to
the talents of an excellent investment management team.

Thank you for entrusting your assets to us.

Sincerely,

/S/ JOHN J. BRENNAN

ADVISOR'S REPORT

In fiscal  2003,  the  Investor  Shares of  Vanguard  International  Growth Fund
returned 9.6%. This compared with a 7.5% rise in the average  international fund
and a 9.1% rise in the Morgan Stanley Capital International Europe, Australasia,
Far East (MSCI EAFE) Index.

THE INVESTMENT ENVIRONMENT

When I wrote to you six months  ago,  stock  markets in most  countries  were at
their worst.  However,  in the ensuing months, many markets performed well; only
the Asian  markets  continued  to fall  under the deadly  influence  of the SARS
(Severe Acute Respiratory  Syndrome) epidemic,  but even that pattern changed at
the end of April. The Asian markets' subsequent rebound closed their performance
gap with Western  markets.  We recognized  the buying  opportunity  this delayed
recovery offered and poured money into Japan, South Korea, and Taiwan.

In hindsight, it is evident that the recovery in global stock markets started in
October in the United States,  led by technology stocks.  However,  progress was
impaired first by the war with Iraq and then by the SARS  outbreak.  Once again,
it is the U.S.  market  and U.S.  consumers  that are  leading  the world out of
recession.  U.S.  monetary and fiscal policy have played major roles, as has the
U.S. dollar's weakness. Outside of the United States, economic recovery has been
very  tentative,  both because the monetary and fiscal  responses have been much
weaker and because many currencies have  strengthened  relative to the dollar--a
disadvantage to exporters, especially in Europe.

- --------------------------------------------------------------------------------
INVESTMENT PHILOSOPHY
The advisor believes that superior long-term  investment results can be achieved
by  selecting  the stocks of  companies  with the  potential  for  above-average
earnings  growth,  with  particular  emphasis on  companies  in  countries  with
favorable business and market environments.
- --------------------------------------------------------------------------------

Surging  economic  growth  in  China  has  been a  major  support  to the  Asian
economies.  This has benefited a range of  industries,  notably basic  materials
like steel and commodities. But these industries are not the natural province of
the International  Growth Fund, which benefits more from the indirect effects of
such booms.  For example,  we have bought  domestic-demand  plays in South Korea
(Shinsegae, a

7


department  store, and insurer Samsung Fire & Marine) and cyclical  companies in
Japan that have distinctive  products,  like capital goods and autos.  Purchases
there included Toyota, SMC, and Mitsubishi Electric.

Another  feature of the fiscal year was the dramatic  recovery in companies with
parlous  balance  sheets and volatile  earnings.  Again,  such companies are not
natural  inhabitants  of our  portfolio,  as we have always  sought  quality and
stability.  So the result that we achieved  during the year came  despite a very
difficult  environment  for the fund's  style of  investing.  We managed to make
money by being broadly in the right markets,  the right  sectors,  and the right
currencies--but not in the stocks that performed best.

OUR SUCCESSES

During  the year,  we had about 10% to 15% of our  portion of the  portfolio  in
emerging  markets,  mostly  in Asia,  as part of a  long-term  strategy  focused
particularly  on  technology  companies.   But,  as  mentioned  above,  we  have
tactically invested in a range of more locally oriented stocks since the turn in
world markets.  This includes  several new holdings in India. On average,  these
investments rose 25% during the year.

I should update you on Samsung  Electronics,  the fund's largest holding,  which
six months ago I highlighted as having fallen steeply. We held on tightly to our
position and have enjoyed a 60% recovery.  For the fiscal year, the stock was up
40%.

Japan remained  depressed for much of the year,  but as noted  earlier,  we took
advantage of the prime investment  opportunity  there and increased our exposure
from a very underweight  position relative to the MSCI EAFE Index,  enabling our
holdings to enjoy a strong recovery since May.

Two long-standing policies of the portfolio also benefited  performance.  First,
we added a lot of value by hedging the risk of a depreciating yen into the euro,
the only currency  (including  the U.S.  dollar) that we expected would be safe.
Significantly, we stopped hedging as the euro reached its peak, and we locked in
a good profit.  Second, despite  higher-than-expected  oil prices and the war in
Iraq,  we held to our negative view on oil stocks.  We were correct:  Oil stocks
underperformed by some 13% as a group.

OUR FAILURES

First among our setbacks,  several  large,  well-known  companies  that had been
teetering  on the edge of  insolvency a year ago rescued  themselves,  and their
share prices more than doubled. Sadly, we held none of them.

8


Second,  we had almost no exposure to Australia and Canada in our portion of the
portfolio.  The currencies of both countries,  which have strong  resource-based
economies,  soared  during  the  period.  And  South  Africa,  where  we have no
exposure, enjoyed a currency that was stronger still.

Third,  we sold  several  stocks  during the  markets'  deterioration  that,  in
retrospect,  we should  have  either kept faith with or waited to sell after the
markets recovered.  Most obviously, we sold all of our portfolio's shares in its
largest holding of a year ago, ING Groep, a Dutch-based  insurance  company.  We
did not lose  confidence  in the  company,  but the  risk of a  market  collapse
devastating   its  balance  sheet  became  too  great  for  us.  The  stock  has
subsequently recovered to a little above our average selling price.

THE FUND'S POSITIONING

The fund is not positioned for a strong global  economic  recovery.  We now have
our  highest  exposure  ever in  emerging  markets--about  15% of the  assets we
manage.  This  reflects our  conviction  that,  owing to their lower cost bases,
Asian-based  companies in  particular  will gain market share from their Western
competitors.

In previous reports I have emphasized that our Japanese  investments are quality
companies  with strong balance  sheets and, for the most part,  relatively  good
pricing power.  These  companies are also more willing to  restructure  than are
typical Japanese companies.  Companies that have these characteristics will fare
best if the incipient  Japanese  economic  recovery,  which has ridden mostly on
exports  to the  United  States  and  China,  does not  extend  broadly  or in a
sustained  manner  into the  domestic  economy.  We have 18% of our  portfolio's
assets in Japan.

About 60% of our portfolio is invested in European companies.  As holds true for
the fund as a whole,  the key to our  success in this region is as much a matter
of companies and sectors selected as of individual country  weightings.  Many of
our European stocks performed  relatively poorly in the past year, but against a
background of continued improvement in profits.  Large,  high-quality  companies
look  comparatively  cheap now, and given the portfolio's clear bias toward such
firms  in  both  Europe  and  Japan,  we look  forward  to a  relatively  strong
performance from such companies in the year ahead.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and  downs of a  comparative  index and an  overall  market
index.  Each 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%.  However,  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 benchmark, and
the less reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
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 comparative index or an
overall market 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.
- --------------------------------------------------------------------------------
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 are taxable to investors).
- --------------------------------------------------------------------------------

PERFORMANCE SUMMARY

As of 8/31/2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

This table  presents  average annual total returns  through the latest  calendar
quarter--rather  than  through  the end of the  fiscal  period.  Securities  and
Exchange Commission rules require that we provide this information.

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 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. However,  they do not reflect the reduced rates on "qualified
dividend income".

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 indicate how it will perform in the future.

ABOUT YOUR FUND EXPENSES

All mutual funds have  operating  expenses.  These  expenses  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 net assets.  This figure is known
as the expense ratio.

A HYPOTHETICAL EXAMPLE

We believe it is  important  for you to  understand  the impact of costs on your
investment.  The following  example  illustrates  the costs that you would incur
over a 12-month  period if you  invested  $10,000 in the fund,  using the fund's
actual return and operating  expenses for the fiscal year ended August 31, 2003.
For comparative  purposes, we also list the average expense ratio for the fund's
peer group, which is derived from data provided by Lipper Inc.

- --------------------------------------------------------------------------------
The funds do not charge transaction fees; these results apply whether or not you
redeemed your  investment at the end of the given period.  Your actual costs may
have been higher or lower,  depending on the amount of your  investment and your
holding period. Peer-group ratios capture data through year-end 2002.

You can find more  information  about a fund's expense ratio,  including  annual
expense ratios for the past five years, in the Financial  Statements  section of
this  report.  For  additional  information  on  operating  expenses  and  other
shareholder  costs,  please  refer  to the  fund's  prospectus.  The  prospectus
presents  hypothetical  shareholder costs over various time periods based upon a
$10,000 investment and a return of 5% a year. This standardized  example,  which
appears in all mutual fund  prospectuses,  may be useful to you in comparing the
costs of investing in different funds.

FINANCIAL STATEMENTS

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
country.  Other assets are added to, and  liabilities  are subtracted  from, the
value of Total  Investments  to calculate  the fund's Net Assets.  Finally,  Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets,  you will find a table displaying the
composition of the fund's net assets.  Because all income and any realized gains
must be distributed to  shareholders  each year, the bulk of net assets consists
of Paid-in  Capital  (money  invested by  shareholders).  The amounts  shown for
Undistributed  Net Investment  Income and Accumulated Net Realized Gains usually
approximate  the sums the fund had available to distribute  to  shareholders  as
income  dividends  or capital  gains as of the  statement  date,  but may differ
because  certain  investments or  transactions  may be treated  differently  for
financial  statement and tax purposes.  Any Accumulated Net Realized Losses, and
any cumulative  excess of  distributions  over net income or net realized gains,
will appear as negative balances.  Unrealized Appreciation (Depreciation) is the
difference  between the market value of the fund's  investments  and their cost,
and reflects the gains  (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the net amount shareholders invested in
or redeemed  from the fund.  Distributions  and Capital Share  Transactions  are
shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

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.

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.  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  in the
calculation of its indexes.

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 protect the value of
securities  and  related  receivables  and  payables  against  changes in future
foreign exchange rates, or 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.

26


4.  Repurchase  Agreements:  The fund,  along with other members of The Vanguard
Group,  transfers  uninvested  cash balances to a pooled cash account,  which is
invested  in  repurchase  agreements  secured  by  U.S.  government  securities.
Securities  pledged  as  collateral  for  repurchase  agreements  are  held by a
custodian bank until the  agreements  mature.  Each agreement  requires that the
market value of the  collateral be sufficient to cover  payments of interest and
principal;  however, in the event of default or bankruptcy by the other party to
the agreement, retention of the collateral may be subject to legal proceedings.

5. 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.

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

7.  Other:  Dividend  income  is  recorded  on the  ex-dividend  date.  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.

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),  shareholder  reporting,  and  proxies.  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. Schroder Investment  Management North America Inc. and, beginning February 6,
2003, 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 Schroder Investment
Management  North  America  Inc. is subject to  quarterly  adjustments  based on
performance for the preceding three years relative to the Morgan Stanley Capital
International  Europe,  Australasia,  Far East  Index.  In  accordance  with the
advisory  contract  entered into with Baillie Gifford  Overseas Ltd. in February
2003, the investment advisory fee will be subject to quarterly adjustments based
on performance  relative to the Morgan  Stanley  Capital  International  Europe,
Australasia, Far East Index beginning December 1, 2003.

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

For the year ended  August 31,  2003,  the  aggregate  investment  advisory  fee
represented  an effective  annual basic rate of 0.13% of the fund's  average net
assets,  before an increase of $526,000  (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, 2003, the fund had contributed capital of $1,088,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 1.09% 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.

27


NOTES TO FINANCIAL STATEMENTS (continued)

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,  2003,  directed  brokerage  and  custodian  fee offset
arrangements reduced expenses by $1,844,000 and $5,000, respectively.  The total
expense  reduction  represented an effective  annual rate of 0.03% 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, 2003,  the fund  realized net foreign  currency
losses of $2,596,000, which decreased distributable net income for tax purposes;
accordingly,  such losses have been  reclassified  from accumulated net realized
losses to undistributed net investment income.

For tax  purposes,  at August 31,  2003,  the fund had  $88,217,000  of ordinary
income  available for  distribution.  The fund had available  realized losses of
$1,405,609,000 to offset future net capital gains of $233,177,000 through August
31, 2010,  $709,774,000 through August 31, 2011, and $462,658,000 through August
31, 2012.

At August 31, 2003, net unrealized appreciation of investment securities for tax
purposes was  $709,701,000,  consisting of unrealized  gains of  $990,635,000 on
securities  that had risen in value since their  purchase  and  $280,934,000  in
unrealized losses on securities that had fallen in value since their purchase.

At August 31, 2003,  the aggregate  settlement  value of open futures  contracts
expiring in September 2003 and the related unrealized appreciation were:

REPORT OF INDEPENDENT AUDITORS

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, 2003, 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 five years in the period then ended,  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 auditing
standards generally accepted in the United States of America, which 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,  2003 by  correspondence  with the  custodian  and
brokers, provide a reasonable basis for our opinion.

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and

personal investments they have made as private individuals.

academia,  and public service to their task of working with Vanguard officers to

This report contains information that can help you evaluate your investment.  It
includes  details  about your fund's  return and presents data and analysis that
provide insight into the fund's performance and investment approach.

By reading the letter from Vanguard's  chairman,  you'll get an understanding of
how the fund invests and how the market  environment  affected its  performance.
The statistical  information that follows can help you understand how the fund's

It's  important  to keep in mind  that  the  opinions  expressed  by  Vanguard's
investment  managers  are just  that:  informed  opinions.  They  should  not be
considered  promises or advice.  The opinions,  like the  statistics,  cover the
period  through the date on the cover of this report.  As things  change--and in
the  financial  markets  you  can be  certain  only  of  change--the  investment
manager's job is to evaluate new information and make adjustments, if necessary.
Of course, the risks of investing in the fund are spelled out in the prospectus.

DISMAL AT THE START, THE STOCK MARKET PERKED UP

A slumping economy,  weak corporate profits, and growing  geopolitical  tensions
weighed  heavily on the stock  market as our fiscal year began,  and a two-month
rally  from  mid-October  quickly  ran  out of  steam.  However,  following  the
successful  conclusion of major combat  operations in Iraq, a distinctly  upbeat
mood began to permeate the

                                       1




marketplace.  Stock prices began to rebound across  capitalizations and industry
sectors in  response to solid  corporate  earnings  announcements  and a slew of
positive economic reports.

- --------------------------------------------------------------------------------
INSTITUTIONAL SHARES

This class of shares  carries  lower  expenses  and is  available  for a minimum
investment of $10 Million.
- --------------------------------------------------------------------------------

     The U.S.  stock market,  as measured by the Wilshire  5000 Index,  returned
14.9% for the fiscal year.  Technology and other  growth-oriented  stocks, which
had  sustained  massive  losses  during the past few years,  were among the most
impressive  gainers.   The  market's  smaller  stocks  outpaced  larger  issues,
demonstrating investors' renewed appetite for risk.

U.S. investors were rewarded with good returns in many international  markets as
well,  although stock  performance was only part of the story.  The weakening of
the U.S.  dollar by almost 10% relative to the euro and Japanese yen transformed
results   that  were   mediocre   by   local-currency   standards   into  strong
dollar-denominated  returns.

INTEREST RATES FELL FOR MONTHS, THEN BOUNCED BACK A BIT

In the bond  market,  the  fiscal  year was marked by two  distinctly  different
phases.  Prior to  mid-June,  the  lethargic  economy and  on-going  flight from
equities to bonds drove the prices of bonds higher and their yields  lower.  The
yield of the  benchmark  10-year U.S.  Treasury note dropped to a 45-year low of
3.11% on June 13. After that point,  however,  longer-term  interest  rates rose
rapidly,  with the yield of the 10-year note standing at 4.46% on August 31. For
the 12 months,  the  Lehman  Brothers  Aggregate  Bond  Index,  a measure of the
taxable investment-grade bond market, provided a total return of 4.4%.

yield  corporate  bonds  performed  spectacularly--the  Lehman High Yield Index,
which  tracks the  performance  of bonds  issued by  com-panies  with low credit
ratings, returned 24.9% for the period.

Short-term  interest  rates  generally  declined  for the 12  months,  but  rose
somewhat toward the end. In an effort to add fuel to the economic recovery,  the
Federal  Reserve Board  trimmed its target for the federal funds rate  twice--in
November  2002 and June  2003--by a total of 75 basis  points  (0.75  percentage
point). The rate stood at 1.00% at the fiscal year-end. The yield of the 3-month
Treasury bill,  which  typically lags Fed moves,  began the fiscal year at 1.67%
and closed at 0.97% after falling to 0.81% in mid-June.

FOR THE FUND, A STRONG SECOND HALF FOLLOWED A POOR START

The  performance  of Vanguard  Calvert  Social Index Fund  reflected the starkly
different  moods in the stock market  during the first and second  halves of the
fiscal  year.  From August 31,  2002,  through  February  28,  2003,  the fund's
Investor Shares returned -5.7%.  During the second half of the year, they gained
22.2%.

The turnaround in the fund's performance mirrored the strong post-war resurgence
of the overall market.  Stocks of companies in the technology,  health care, and
consumer discretionary  sectors--which  together accounted for 55% of the fund's
assets at the fiscal year-end-- posted strong results and were among the largest
contributors to the fund's return.

The  contribution  of technology  stocks to the fund's  success is  particularly
noteworthy,  as these stocks severely hampered performance in 2001 and 2002. For
2003, the fund's tech holdings rose more than 32%. The fund's  relatively  large
allocation to such stocks, in both up markets and down,  results from the social
screens of the target  Calvert  Social Index.  The index  criteria  exclude many
companies in older industries that generally fall into the value stock category,
thus producing a lineup with a tilt toward growth sectors such as technology.

Also boosting performance was a rebound in financial services stocks, the fund's
largest sector at 29% of assets.  These stocks experienced steep losses early in
the fiscal year, when investors were repelled by headlines about  accounting and
management  misdeeds,  but the group  recovered to gain about 7% for the full 12
months.

THE FUND'S RECORD SINCE INCEPTION REFLECTS A TOUGH MARKET

Vanguard  Calvert Social Index Fund began operations on May 31, 2000, just after
the onset of what proved to be a severe  three-year  downturn in the U.S.  stock
market.  As  a  result,   the  fund's   since-inception   performance  is  quite
disappointing.  Viewed in context,  however,  things  look a bit better.  As the
chart at left  shows,  the fund has met its  mandate to closely  track the total
return of the Calvert Social Index and has fared significantly  better--that is,
lost  less--than  the average  large-cap  growth fund. An initial  investment of
$10,000 in the fund would  have been worth  $6,994 on August 31,  while the same
investment in the average peer would have resulted in some $1,100 less.

*Fund inception.

Through  both  good and bad  markets,  one  factor  that  enhances  your  fund's
long-term  competitiveness  is its low operating costs.  During fiscal 2003, for
example,  the fund's Investor Shares had an expense ratio (operating expenses as
a percentage of average net assets) of 0.25%, or $2.50 per $1,000 invested--just
a fraction of the 1.57%, or $15.70 per $1,000  invested,  charged by the average
large-cap  growth fund. Our  Institutional  Shares enjoyed an even lower expense
ratio of 0.12%  (annualized since inception on January 14). Over time, these low
costs mean that more of your fund's returns stay in your account, where they can
keep working for you.

KEEP YOUR FOCUS ON A LONG-TERM INVESTMENT PLAN

The stock  market  looked more  enticing in the past few months than it had in a
long time.  Does that mean we should  expect even better  things to come? Is now
the "right" time to put more assets in stocks?

The truth is that not even the most  skilled  market-watcher  can  answer  those
questions.  Nobody knows what the future  holds for any asset class.  That's why
Vanguard has always  advocated a balanced,  long-term  investment  approach that
includes a mix of stock,  bond,  and money  market  funds  appropriate  for your
unique goals,  financial  circumstances,  and risk tolerance.  Vanguard  Calvert

Fund, which exemplifies both the principles of socially  screened  investing and
the  benefits  of  indexing--broad  diversification,  tax  efficiency,  and  low
costs--can serve a role in such a portfolio.

Thank you for your continued confidence in Vanguard.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation to the ups and downs of the fund's  target  index or an overall  market
index.  Each 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%.  However,  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 benchmark, and
the less reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
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 American 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 the fund's  target index
or by an  overall  market  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.
- --------------------------------------------------------------------------------
TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------
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
dividends paid on stocks in the index.

PERFORMANCE SUMMARY                                              AS OF 8/31/2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

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 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. However,  they do not reflect the reduced rates on "qualified
dividend income."

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 indicate how it will perform in the future.

                            ABOUT YOUR FUND EXPENSES

All mutual funds have  operating  expenses.  These  expenses  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 net assets.  This figure is known
as the expense ratio.

A HYPOTHETICAL EXAMPLE

We believe it is  important  for you to  understand  the impact of costs on your
investment.  The following  example  illustrates  the costs that you would incur
over a 12-month  period if you  invested  $10,000 in the fund,  using the fund's
actual return and operating  expenses for the fiscal year ended August 31, 2003.
For comparative  purposes, we also list the average expense ratio for the fund's
peer group, which is derived from data provided by Lipper Inc.

The funds do not charge transaction fees; these results apply whether or not you

have been higher or lower,  depending on the amount of your  investment and your
holding period. Peer-group ratios capture data through year-end 2002.


You can find more  information  about a fund's expense ratio,  including  annual
expense ratios for the past five years, in the Financial  Statements  section of
this  report.  For  additional  information  on  operating  expenses  and  other
shareholder  costs,  please  refer  to the  fund's  prospectus.  The  prospectus
presents  hypothetical  shareholder costs over various time periods based upon a
$10,000 investment and a return of 5% a year. This standardized  example,  which
appears in all mutual fund  prospectuses,  may be useful to you in comparing the
costs of investing in different funds.

FINANCIAL STATEMENTS                                             AS OF 8/31/2003

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments to calculate the fund's Net Assets.  Finally, Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets,  you will find a table displaying the
composition of the fund's net assets.  Because all income and any realized gains
must be distributed to  shareholders  each year, the bulk of net assets consists
of Paid-in  Capital  (money  invested by  shareholders).  The amounts  shown for
Undistributed  Net Investment  Income and Accumulated Net Realized Gains usually
approximate  the sums the fund had available to distribute  to  shareholders  as
income  dividends  or capital  gains as of the  statement  date,  but may differ
because  certain  investments or  transactions  may be treated  differently  for
financial  statement and tax purposes.  Any Accumulated Net Realized Losses, and
any cumulative  excess of  distributions  over net income or net realized gains,
will appear as negative balances.  Unrealized Appreciation (Depreciation) is the
difference  between the market value of the fund's  investments  and their cost,
and reflects the gains  (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by purchasing shares or by reinvesting  distributions,  as well as
the amounts redeemed.  The  corresponding  numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

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 were first issued on January 14, 2003,  and
are  designed  for  investors  who meet  certain  administrative  and  servicing
criteria and invest a minimum of $10 million.

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.  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   temp-orary  cash   investments  are  valued  at  amortized  cost,  which
approximates market value.

     2.  REPURCHASE  AGREEMENTS:  The fund,  along  with  other  members  of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.

     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. OTHER:  Dividend  income is recorded on the ex-dividend  date.  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),  shareholder  reporting,  and  proxies.  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, 2003, the fund had contributed
capital of $26,000 to Vanguard (included in Other Assets), representing 0.02% 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.

                                       25

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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, 2003, the fund had $1,036,000 of ordinary income
available  for  distribution.   The  fund  had  available   realized  losses  of
$11,904,000  to offset  future net capital gains of $57,000  through  August 31,
2009,  $3,511,000  through August 31, 2010,  $5,505,000 through August 31, 2011,
and $2,831,000 through August 31, 2012.

At August 31, 2003, net unrealized depreciation of investment securities for tax
purposes was  $15,553,000,  consisting of  unrealized  gains of  $12,905,000  on
securities  that had risen in value  since their  purchase  and  $28,458,000  in
unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended  August 31, 2003,  the fund  purchased  $64,792,000  of
investment  securities and sold $16,060,000 of investment  securities other than
temporary cash investments.

E. The market value of securities on loan to  broker/dealers at August 31, 2003,
was  $76,000,  for  which the fund held cash  collateral  of  $78,000.  The fund
invests  cash  collateral  received  in  repurchase  agreements,  and  records a
liability for the return of the collateral, during the period the securities are
on loan.

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

REPORT OF INDEPENDENT AUDITORS

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, 2003, 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  auditing  standards
generally  accepted in the United States of America,  which 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, 2003 by  correspondence  with the custodian,  provide a reasonable basis for
our opinion.

                             CAPITALIZE ON YOUR IRA

Are you taking full advantage of your individual  retirement account? You really
should be. The contribution  limits on IRAs were recently  raised,  making these
tax-deferred accounts more powerful options for retirement savers.

Here's how you can exploit  your  IRA--and  improve  your  chances of having the
retirement of your dreams.

CONTRIBUTE THE MAXIMUM AMOUNT EACH YEAR

It may be an  obvious  point,  but if you  invest as much in your IRA as the law
allows--currently  $3,000 per tax year if you are under age 50 and $3,500 if you
are age 50 or over--you will increase the odds of meeting your retirement goals.
"Max out" every year you can.

MAKE IT AUTOMATIC

Put your IRA on autopilot by taking advantage of Vanguard's Automatic Investment
Plan.  Your IRA  contributions  will be  deducted  from your bank  account  on a
schedule of your choosing, making retirement investing a healthy habit.

CONSIDER COST

The owners of low-cost  investments keep a larger portion of their gross returns
than the owners of high-cost investments.  Over the long term, avoiding costlier
mutual funds and brokerage commissions could significantly boost your retirement
savings.Our low costs are one reason a Vanguard IRA(R) is such a smart choice.

REQUEST A DIRECT ROLLOVER WHEN YOU CHANGE JOBS

Don't spend your retirement assets before you've retired.  When you change jobs,
roll your 401(k) or other  employer-sponsored  retirement  plan assets  directly
into your IRA.

If you have  questions  about your IRA,  want to  transfer  an IRA from  another
institution to Vanguard,  or need help with any other IRA transaction,  call our
Retirement Resource Center at 1-800-205-6189 or visit VANGUARD.COM. You can open
or fund your IRA on our  website  and have a  confirmation  in your hand  within
minutes.

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.

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

This report contains information that can help you evaluate your investment.  It
includes  details  about your fund's  return and presents data and analysis that
provide insight into the fund's performance and investment approach.

By reading the letter from Vanguard's  chairman,  you'll get an understanding of

investment  managers  are just  that:  informed  opinions.  They  should  not be

period  through the date on the cover of this report.  As things  change--and in
the  financial  markets  you  can be  certain  only  of  change--the  investment
manager's job is to evaluate new information and make adjustments, if necessary.
Of course, the risks of investing in the fund are spelled out in the prospectus.

DISMAL AT THE START, THE STOCK MARKET PERKED UP

A slumping economy,  weak corporate profits, and growing  geopolitical  tensions
weighed  heavily on the stock  market as our fiscal year began,  and a two-month
rally  from  mid-October  quickly  ran  out of  steam.  However,  following  the
successful  conclusion of major combat  operations in Iraq, a distinctly  upbeat
mood began to permeate the

                                       1




marketplace.  Stock prices began to rebound across  capitalizations and industry
sectors in  response to solid  corporate  earnings  announcements  and a slew of
positive economic reports.

- --------------------------------------------------------------------------------
INSTITUTIONAL SHARES

This class of shares  carries  lower  expenses  and is  available  for a minimum
investment of $10 Million.
- --------------------------------------------------------------------------------

     The U.S.  stock market,  as measured by the Wilshire  5000 Index,  returned
14.9% for the fiscal year.  Technology and other  growth-oriented  stocks, which
had  sustained  massive  losses  during the past few years,  were among the most
impressive  gainers.   The  market's  smaller  stocks  outpaced  larger  issues,
demonstrating investors' renewed appetite for risk.

U.S. investors were rewarded with good returns in many international  markets as
well,  although stock  performance was only part of the story.  The weakening of
the U.S.  dollar by almost 10% relative to the euro and Japanese yen transformed
results   that  were   mediocre   by   local-currency   standards   into  strong
dollar-denominated  returns.

INTEREST RATES FELL FOR MONTHS, THEN BOUNCED BACK A BIT

In the bond  market,  the  fiscal  year was marked by two  distinctly  different
phases.  Prior to  mid-June,  the  lethargic  economy and  on-going  flight from
equities to bonds drove the prices of bonds higher and their yields  lower.  The
yield of the  benchmark  10-year U.S.  Treasury note dropped to a 45-year low of
3.11% on June 13. After that point,  however,  longer-term  interest  rates rose
rapidly,  with the yield of the 10-year note standing at 4.46% on August 31. For
the 12 months,  the  Lehman  Brothers  Aggregate  Bond  Index,  a measure of the
taxable investment-grade bond market, provided a total return of 4.4%.

yield  corporate  bonds  performed  spectacularly--the  Lehman High Yield Index,
which  tracks the  performance  of bonds  issued by  com-panies  with low credit
ratings, returned 24.9% for the period.

Short-term  interest  rates  generally  declined  for the 12  months,  but  rose
somewhat toward the end. In an effort to add fuel to the economic recovery,  the
Federal  Reserve Board  trimmed its target for the federal funds rate  twice--in
November  2002 and June  2003--by a total of 75 basis  points  (0.75  percentage
point). The rate stood at 1.00% at the fiscal year-end. The yield of the 3-month
Treasury bill,  which  typically lags Fed moves,  began the fiscal year at 1.67%
and closed at 0.97% after falling to 0.81% in mid-June.

FOR THE FUND, A STRONG SECOND HALF FOLLOWED A POOR START

The  performance  of Vanguard  Calvert  Social Index Fund  reflected the starkly
different  moods in the stock market  during the first and second  halves of the
fiscal  year.  From August 31,  2002,  through  February  28,  2003,  the fund's
Investor Shares returned -5.7%.  During the second half of the year, they gained
22.2%.

The turnaround in the fund's performance mirrored the strong post-war resurgence
of the overall market.  Stocks of companies in the technology,  health care, and
consumer discretionary  sectors--which  together accounted for 55% of the fund's
assets at the fiscal year-end-- posted strong results and were among the largest
contributors to the fund's return.

The  contribution  of technology  stocks to the fund's  success is  particularly
noteworthy,  as these stocks severely hampered performance in 2001 and 2002. For
2003, the fund's tech holdings rose more than 32%. The fund's  relatively  large
allocation to such stocks, in both up markets and down,  results from the social
screens of the target  Calvert  Social Index.  The index  criteria  exclude many
companies in older industries that generally fall into the value stock category,
thus producing a lineup with a tilt toward growth sectors such as technology.

Also boosting performance was a rebound in financial services stocks, the fund's
largest sector at 29% of assets.  These stocks experienced steep losses early in
the fiscal year, when investors were repelled by headlines about  accounting and
management  misdeeds,  but the group  recovered to gain about 7% for the full 12
months.

THE FUND'S RECORD SINCE INCEPTION REFLECTS A TOUGH MARKET

Vanguard  Calvert Social Index Fund began operations on May 31, 2000, just after
the onset of what proved to be a severe  three-year  downturn in the U.S.  stock
market.  As  a  result,   the  fund's   since-inception   performance  is  quite
disappointing.  Viewed in context,  however,  things  look a bit better.  As the
chart at left  shows,  the fund has met its  mandate to closely  track the total
return of the Calvert Social Index and has fared significantly  better--that is,
lost  less--than  the average  large-cap  growth fund. An initial  investment of
$10,000 in the fund would  have been worth  $6,994 on August 31,  while the same
investment in the average peer would have resulted in some $1,100 less.

*Fund inception.

Through  both  good and bad  markets,  one  factor  that  enhances  your  fund's
long-term  competitiveness  is its low operating costs.  During fiscal 2003, for
example,  the fund's Investor Shares had an expense ratio (operating expenses as
a percentage of average net assets) of 0.25%, or $2.50 per $1,000 invested--just
a fraction of the 1.57%, or $15.70 per $1,000  invested,  charged by the average
large-cap  growth fund. Our  Institutional  Shares enjoyed an even lower expense
ratio of 0.12%  (annualized since inception on January 14). Over time, these low
costs mean that more of your fund's returns stay in your account, where they can
keep working for you.

KEEP YOUR FOCUS ON A LONG-TERM INVESTMENT PLAN

The stock  market  looked more  enticing in the past few months than it had in a
long time.  Does that mean we should  expect even better  things to come? Is now
the "right" time to put more assets in stocks?

The truth is that not even the most  skilled  market-watcher  can  answer  those
questions.  Nobody knows what the future  holds for any asset class.  That's why
Vanguard has always  advocated a balanced,  long-term  investment  approach that
includes a mix of stock,  bond,  and money  market  funds  appropriate  for your
unique goals,  financial  circumstances,  and risk tolerance.  Vanguard  Calvert

Fund, which exemplifies both the principles of socially  screened  investing and
the  benefits  of  indexing--broad  diversification,  tax  efficiency,  and  low
costs--can serve a role in such a portfolio.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation to the ups and downs of the fund's  target  index or an overall  market
index.  Each 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%.  However,  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 benchmark, and
the less reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
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 American 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 the fund's  target index
or by an  overall  market  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.
- --------------------------------------------------------------------------------
TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------
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
dividends paid on stocks in the index.

PERFORMANCE SUMMARY                                              AS OF 8/31/2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

This table  presents  average annual total returns  through the latest  calendar
quarter--rather  than  through  the end of the  fiscal  period.  Securities  and
Exchange Commission rules require that we provide this information.

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 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. However,  they do not reflect the reduced rates on "qualified
dividend income."

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 indicate how it will perform in the future.

                            ABOUT YOUR FUND EXPENSES

All mutual funds have  operating  expenses.  These  expenses  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 net assets.  This figure is known
as the expense ratio.

A HYPOTHETICAL EXAMPLE

We believe it is  important  for you to  understand  the impact of costs on your
investment.  The following  example  illustrates  the costs that you would incur
over a 12-month  period if you  invested  $10,000 in the fund,  using the fund's
actual return and operating  expenses for the fiscal year ended August 31, 2003.
For comparative  purposes, we also list the average expense ratio for the fund's
peer group, which is derived from data provided by Lipper Inc.

*    Annualized; the Institutional Shares' inception was January 14, 2003.
The funds do not charge transaction fees; these results apply whether or not you
redeemed your  investment at the end of the given period.  Your actual costs may
have been higher or lower,  depending on the amount of your  investment and your
holding period. Peer-group ratios capture data through year-end 2002.


You can find more  information  about a fund's expense ratio,  including  annual
expense ratios for the past five years, in the Financial  Statements  section of
this  report.  For  additional  information  on  operating  expenses  and  other
shareholder  costs,  please  refer  to the  fund's  prospectus.  The  prospectus
presents  hypothetical  shareholder costs over various time periods based upon a
$10,000 investment and a return of 5% a year. This standardized  example,  which
appears in all mutual fund  prospectuses,  may be useful to you in comparing the
costs of investing in different funds.

FINANCIAL STATEMENTS                                             AS OF 8/31/2003

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments to calculate the fund's Net Assets.  Finally, Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets,  you will find a table displaying the
composition of the fund's net assets.  Because all income and any realized gains
must be distributed to  shareholders  each year, the bulk of net assets consists
of Paid-in  Capital  (money  invested by  shareholders).  The amounts  shown for
Undistributed  Net Investment  Income and Accumulated Net Realized Gains usually
approximate  the sums the fund had available to distribute  to  shareholders  as
income  dividends  or capital  gains as of the  statement  date,  but may differ
because  certain  investments or  transactions  may be treated  differently  for
financial  statement and tax purposes.  Any Accumulated Net Realized Losses, and
any cumulative  excess of  distributions  over net income or net realized gains,
will appear as negative balances.  Unrealized Appreciation (Depreciation) is the
difference  between the market value of the fund's  investments  and their cost,
and reflects the gains  (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by purchasing shares or by reinvesting  distributions,  as well as
the amounts redeemed.  The  corresponding  numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

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 were first issued on January 14, 2003,  and
are  designed  for  investors  who meet  certain  administrative  and  servicing
criteria and invest a minimum of $10 million.

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.  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   temp-orary  cash   investments  are  valued  at  amortized  cost,  which
approximates market value.

     2.  REPURCHASE  AGREEMENTS:  The fund,  along  with  other  members  of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.

     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. OTHER:  Dividend  income is recorded on the ex-dividend  date.  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),  shareholder  reporting,  and  proxies.  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, 2003, the fund had contributed
capital of $26,000 to Vanguard (included in Other Assets), representing 0.02% 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.

                                       25

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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, 2003, the fund had $1,036,000 of ordinary income
available  for  distribution.   The  fund  had  available   realized  losses  of
$11,904,000  to offset  future net capital gains of $57,000  through  August 31,
2009,  $3,511,000  through August 31, 2010,  $5,505,000 through August 31, 2011,
and $2,831,000 through August 31, 2012.

At August 31, 2003, net unrealized depreciation of investment securities for tax
purposes was  $15,553,000,  consisting of  unrealized  gains of  $12,905,000  on
securities  that had risen in value  since their  purchase  and  $28,458,000  in
unrealized losses on securities that had fallen in value since their purchase.

D. During the year ended  August 31, 2003,  the fund  purchased  $64,792,000  of
investment  securities and sold $16,060,000 of investment  securities other than
temporary cash investments.

E. The market value of securities on loan to  broker/dealers at August 31, 2003,
was  $76,000,  for  which the fund held cash  collateral  of  $78,000.  The fund
invests  cash  collateral  received  in  repurchase  agreements,  and  records a
liability for the return of the collateral, during the period the securities are
on loan.

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

REPORT OF INDEPENDENT AUDITORS

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, 2003, 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  auditing  standards
generally  accepted in the United States of America,  which 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, 2003 by  correspondence  with the custodian,  provide a reasonable basis for
our opinion.

                             CAPITALIZE ON YOUR IRA

Are you taking full advantage of your individual  retirement account? You really
should be. The contribution  limits on IRAs were recently  raised,  making these
tax-deferred accounts more powerful options for retirement savers.

Here's how you can exploit  your  IRA--and  improve  your  chances of having the
retirement of your dreams.

CONTRIBUTE THE MAXIMUM AMOUNT EACH YEAR

It may be an  obvious  point,  but if you  invest as much in your IRA as the law
allows--currently  $3,000 per tax year if you are under age 50 and $3,500 if you
are age 50 or over--you will increase the odds of meeting your retirement goals.
"Max out" every year you can.

MAKE IT AUTOMATIC

Put your IRA on autopilot by taking advantage of Vanguard's Automatic Investment
Plan.  Your IRA  contributions  will be  deducted  from your bank  account  on a
schedule of your choosing, making retirement investing a healthy habit.

CONSIDER COST

The owners of low-cost  investments keep a larger portion of their gross returns
than the owners of high-cost investments.  Over the long term, avoiding costlier
mutual funds and brokerage commissions could significantly boost your retirement
savings.Our low costs are one reason a Vanguard IRA(R) is such a smart choice.

REQUEST A DIRECT ROLLOVER WHEN YOU CHANGE JOBS

Don't spend your retirement assets before you've retired.  When you change jobs,
roll your 401(k) or other  employer-sponsored  retirement  plan assets  directly
into your IRA.

If you have  questions  about your IRA,  want to  transfer  an IRA from  another
institution to Vanguard,  or need help with any other IRA transaction,  call our
Retirement Resource Center at 1-800-205-6189 or visit VANGUARD.COM. You can open
or fund your IRA on our  website  and have a  confirmation  in your hand  within
minutes.

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
