Item 1. Report to Shareholders

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       Strategic Sector Municipal Trust performed during the annual period. The
       portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the trust's financial statements and a list of trust investments
       as of October 31, 2003.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that the trust will achieve its investment
       objective. The trust is subject to market risk, which is the possibility
       that the market values of securities owned by the trust will decline and,
       therefore, the value of the trust shares may be less than what you paid
       for them. Accordingly, you can lose money investing in this trust.

As a result of recent market activity, current performance may vary from the
figures shown. For more up-to-date information, please visit vankampen.com or
speak with your financial advisor. The NAV per share is determined by dividing
the value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding. The common share
market price is the price the market is willing to pay for shares of the trust
at a given time. Common share market price is influenced by a range of factors,
including supply and demand and market conditions. Total return assumes an
investment at the beginning of the period, reinvestment of all distributions for
the period in accordance with the trust's dividend reinvestment plan, and sale
of all shares at the end of the period.

The Lehman Brothers Municipal Bond Index is a broad-based statistical composite
of municipal bonds. The index is unmanaged and does not include any sales

Trust Report

FOR THE 12-MONTH PERIOD ENDED OCTOBER 31, 2003

Van Kampen Strategic Sector Municipal Trust is managed by the adviser's
Municipal Fixed Income team.(1) Current members include Timothy D. Haney, Vice
President; Robert Wimmel, Vice President; and John Reynoldson, Executive
Director.

MARKET CONDITIONS

The economic backdrop for the 12 months ended October 31 was largely
characterized by the persistent weakness of the U.S. economy. One of the most
closely watched economic indicators, employment strength, was in negative
territory for much of the period. Repeated comments from government and
private-sector economists suggesting that the U.S. economy might be entering a
deflationary period also seemed to weigh heavily on the minds of investors over
the course of the year. At the same time, ongoing budgetary and fiscal
difficulties at the state and local level contributed to ratings downgrades for
many municipal bonds. The Federal Reserve Board (the Fed) attempted to allay
these fears and keep the economy moving in the right direction by cutting the
Fed Funds target rate twice during the period to a level of 1.00 percent.
Although the stock markets appeared to look past the sluggish economic data,
bonds, in general, were hampered.

While yields on intermediate- and long-term bonds ended the period roughly where
they began, the road between those two points was decidedly bumpy. The 12-month
period can be divided into two distinct market environments. The first of these,
which lasted from October 2002 to mid-June 2003, saw municipal yields fall by
roughly 80 basis points to levels not seen since the late 1960s. These
plummeting yields led to a surge in issuance as municipalities moved to lock in
low financing and, in the case of older bonds, low refinancing costs. These
record levels of supply met with substantial demand as investors in search of
relative stability poured cash into municipal bond funds. Demand for municipal
bonds was also strong from so-called "cross-over" buyers--investors who
traditionally favor taxable investments, but were drawn to the relatively
attractive yields of municipal bonds.

The municipal market reversed abruptly in mid-June, when yields began to climb
from their lows. Investors during this phase shifted their attention to the
advancing equity market, which reduced demand for municipal bonds. Interest from
cross-over investors also evaporated as the relative attractiveness of the
taxable market returned. Issuance remained strong throughout this leg of the
period, though it abated somewhat in the last three months of the reporting
year. These forces combined to drive municipal bond yields off of their historic
lows, ending the period where they began.

PERFORMANCE ANALYSIS

The trust's return can be calculated based upon either the market price or the
net asset value (NAV) of its shares. NAV per share is determined by dividing the
value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding, while market
price reflects the supply and demand for the shares. As a result, the two
returns can differ significantly. On both a market price and an NAV basis, the
trust outperformed its benchmark, the Lehman Brothers Municipal Bond Index. (See
table below.)

The trust's significant position in health-care bonds generated attractive
income, as well as price appreciation driven by yield-seeking investors drawn to
the bonds' relatively robust yields. Certain issues in this sector met their
investment objectives during the period, and we subsequently sold them in favor
of bonds with superior total-return potential. Our current strategy of avoiding
housing bonds also helped the trust; the sector performed poorly amidst record
levels of mortgage refinancing activity.

The trust uses leverage to enhance its dividend to common shareholders by
borrowing money at short-term rates through the issuance of preferred shares.
The proceeds are reinvested in longer-term securities, taking advantage of the
difference between short- and longer-term rates. With short-term rates at
historic lows during the period, the difference between short- and longer-term
rates was relatively high. This made using leverage a particularly profitable
approach during the period, and added to the trust's strong performance.

While the trust outperformed its benchmark, not all of its positions performed
strongly over the entire period in question. With interest rates falling to
historic lows, our analysis showed an increasing possibility of a damaging
upward shift in interest rates. Therefore, we positioned the trust defensively
by maintaining a duration (a measure of interest-rate sensitivity) that was
slightly shorter than that of the benchmark during the period. This position
helped the trust when rates climbed, but kept it from fully participating in the
bond market rally earlier in the period.

We attempted to be equally defensive in managing the portfolio's maturity
structure. Given the steepness of the yield curve for much of the period
(steepness is a measure of the difference in yields between long- and short-
maturity securities), we focused on a strategy designed to outperform in a

curve-flattening environment. We purchased premium bonds in the 14- to 20-year
range that were priced to 10-year call dates. These bonds offer attractive
yields compared to bonds with similar interest-rate risk. We sold bonds in the
5- to 10-year range, an area of the curve that we feel will underperform if
short rates rise. This curve flattening did not occur as early as we
anticipated, however, and the strategy hampered performance when short rates
fell in the first part of the period. However, when long-bond yields rose in the
latter part of the period, our emphasis on defensive bonds in the 14- to 20-year
range helped to preserve principal.

In addition to this core strategy, we also traded high-grade bonds in the
30-year range based on relative-value fluctuations. We sought out issues that
were cheap relative to comparable bonds, and then sold them after they achieved
their performance targets in order to reinvest the proceeds into securities that
we believe have greater total-return prospects.

During the period, many municipalities faced budget shortfalls and potential
credit downgrades. In this challenging environment, we sought to preserve
principal by emphasizing the highest credit-quality tiers of the municipal bond
market. As of October 31, 2003, approximately 84 percent of the trust's long-
term investments were invested in bonds rated AA and above. We will continue
with our disciplined investment approach, monitoring the market closely for
compelling opportunities.

(a) As required, effective November 1, 2001, the Trust has adopted the
    provisions of the AICPA Audit and Accounting Guide for Investment companies
    and began accreting market discount on fixed income securities. The effect
    of this change for the year ended October 31, 2002 was to increase net
    investment income per share by $.03, decrease net realized and unrealized
    gains and losses per share by $.03 and increase the ratio of net investment
    income to average net assets applicable to common shares by .19%. Per share,
    ratios and supplemental data for periods prior to October 31, 2002 have not
    been restated to reflect this change in presentation.

(b) Total return assumes an investment at the common share market price at the
    beginning of the period indicated, reinvestment of all distributions for the
    period in accordance with the Trust's dividend reinvestment plan, and sale
    of all shares at the closing common share market price at the end of the
    period indicated.

(c) Ratios do not reflect the effect of dividend payments to preferred
    shareholders.

(d) Ratios reflect the effect of dividend payments to preferred shareholders.

(e) Calculated by subtracting the Trust's total liabilities (not including the
    preferred shares) from the Trust's total assets and dividing this by the
    number of preferred shares outstanding.

NOTES TO
FINANCIAL STATEMENTS

October 31, 2003

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Strategic Sector Municipal Trust (the "Trust") is registered as a
non-diversified, closed-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Trust's investment
objective is to seek to provide a high level of current income exempt from
federal income tax, consistent with preservation of capital. The Trust will
invest in a portfolio consisting substantially of municipal obligations from
those market sectors which the Adviser feels will best meet the Trust's
investment objective. The Trust commenced investment operations on January 22,
1993.

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Trust may purchase and sell securities on a "when-issued" or "delayed delivery"
basis with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Trust will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At October 31, 2003, the Trust did not have any when-issued or
delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    The Trust intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset

such losses against any future realized capital gains. At October 31, 2003, the
Trust had an accumulated capital loss carryforward for tax purposes of
$3,365,379, which will expire between October 31, 2004 and October 31, 2008. Of
this amount, $1,702,886 will expire on October 31, 2004.

    At October 31, 2003 the cost and related gross unrealized appreciation and
depreciation are as follows:

E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly
dividends from net investment income to common shareholders. Net realized gains,
if any, are distributed annually on a pro rata basis to common and preferred
shareholders. Distributions from net realized gains for book purposes may
include short-term capital gains and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the years ended October 31,
2003 and 2002 were as follows:

                                                              =======    ========
</Table>

    Due to inherent differences in the recognition of income, expenses and
realized gains/ losses under accounting principles generally accepted in the
United States of America and federal income tax purposes, permanent differences
between book and tax basis reporting have been identified and appropriately
reclassified on the Statement of Assets and Liabilities. A permanent book and
tax difference relating to a portion of the capital loss carryforward expiring
in the current year totaling $1,323,361 was reclassified from accumulated net
realized loss to paid in surplus. Additionally, a permanent book and tax
difference relating to expenses which are not deductible for tax purposes
totaling $965 was reclassified from accumulated undistributed net investment
income to paid in surplus. Also, a permanent book and tax difference relating to
book and tax accretion differences totaling $559,416 was reclassified from
accumulated undistributed net investment income to accumulated net realized
loss.

    As of October 31, 2003, the components of distributable earnings on a tax
basis were as follows:

    Net realized gains and losses may differ for financial reporting purposes
primarily as a result of gains or losses recognized for tax purposes on open
future transactions on October 31, 2003.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, Van Kampen
Investment Advisory Corp. (the "Adviser") will provide investment advice and
facilities to the Trust for an annual fee payable monthly of .65% of the average
daily net assets of the Trust. In addition, the Trust will pay a monthly
administrative fee to Van Kampen Investments Inc. or its affiliates'
(collectively "Van Kampen"), the Trust's Administrator, at an annual rate of
..10% of the average daily net assets of the Trust. The administrative services
provided by the Administrator include record keeping and reporting
responsibilities with respect to the Trust's portfolio and preferred shares and
providing certain services to shareholders.

    For the year ended October 31, 2003, the Trust recognized expenses of
approximately $16,900 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of
the Trust is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Trust. The Adviser
allocates the cost of such services to each trust. For the year ended October
31, 2003, the Trust recognized expenses of approximately $34,400 representing
Van Kampen's cost of providing accounting and legal services to the Trust, which
are reported as part of "Other" and "Legal" expenses, respectively, in the
Statement of Operations.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
officers of Van Kampen.

    The Trust provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable upon retirement for a
ten-year period and are based upon each trustee's years of service to the Trust.
The maximum annual benefit per trustee under the plan is $2,500.

3. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $82,012,889 and $96,060,281,
respectively.

4. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or
fixed-income market changes, for duration management or for risk management
purposes,

but may also enter into these transactions to generate additional income. All of
the Trust's portfolio holdings, including derivative instruments, are marked to
market each day with the change in value reflected in the unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying the futures contract.

    During the period, the Trust invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Trust
generally invests in exchange traded futures on U.S. Treasury Bonds and Notes
and typically closes the contract prior to delivery date. Upon entering into
futures contracts, the Trust maintains an amount of cash or liquid securities
with a value equal to a percentage of the contract amount with either a future
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the year ended October 31, 2003, were

REPORT OF INDEPENDENT AUDITORS

To the Board of Trustees and Shareholders of Van Kampen Strategic Sector
Municipal Trust:

We have audited the accompanying statement of assets and liabilities of Van
Kampen Strategic Sector Municipal Trust (the "Trust"), including the portfolio
of investments, as of October 31, 2003, the related statement of operations for
the year then ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
four years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The Trust's financial highlights for the periods ended
prior to October 31, 2000, were audited by other auditors whose report, dated
December 6, 1999, expressed an unqualified opinion on those financial
highlights.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2003, by correspondence with the Trust's
custodian; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen Strategic Sector Municipal Trust as of October 31, 2003, the results of
its operations, the changes in its net assets and the financial highlights for
the respective stated periods, in conformity with accounting principles
generally accepted in the United States of America.

                                                                              23


DIVIDEND REINVESTMENT PLAN

    The Trust offers a Dividend Reinvestment Plan (the "Plan") pursuant to which
Common Shareholders who are participants in the Plan may have dividends and
capital gains distributions automatically reinvested in Common Shares of the
Trust. All Common Shareholders are deemed to be participants in the Plan unless
they specifically elect not to participate. Common Shareholders who elect not to
participate in the Plan will receive all distributions of dividends and capital
gains in cash paid by check mailed directly to the Common Shareholder by the
Trust's dividend disbursing agent.

HOW THE PLAN WORKS

    State Street Bank and Trust Company, as your Plan Agent, serves as agent for
the Common Shareholders in administering the Plan. After the Trust declares a
dividend or determines to make a capital gains distribution, the Plan Agent
will, as agent for the participants, receive the cash payment and use it to buy
Common Shares in the open market, on the New York Stock Exchange or elsewhere,
for the participants' accounts. The Trust will not issue any new Common Shares
in connection with the Plan. All reinvestments are in full and fractional Common
Shares, carried to three decimal places.

    Experience under the Plan may indicate that changes are desirable.
Accordingly, the Trust reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
change sent to all Common Shareholders of the Trust at least 90 days before the
record date for the dividend or distribution. The Plan also may be amended or
terminated by the Plan Agent by at least 90 days written notice to all Common
Shareholders of the Trust.

COSTS OF THE PLAN

    The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions will be paid by the Trust. However, each participant will pay a
pro rata share of brokerage commissions incurred with respect to the Plan
Agent's open market purchases in connection with the reinvestment of dividends
and distributions. No other charges will be made to participants for reinvesting
dividends or capital gains distributions, except for certain brokerage
commissions, as described above.

TAX IMPLICATIONS

    You will receive tax information annually for your personal records and to
help you prepare your federal income tax return. The automatic reinvestment of
dividends and capital gains distributions does not relieve you of any income tax
which may be payable on dividends or distributions.

 24


RIGHT TO WITHDRAW

    All Common Shareholders of the Trust are deemed to be participants in the
Plan unless they specifically elect not to participate. You may withdraw from
the Plan at any time by calling 1-800-341-2929 or by writing State Street Bank
and Trust Company, P.O. Box 8200, Boston, MA 02266-8200. If you withdraw, you
will receive, without charge, a share certificate issued in your name for all
full Common Shares credited to your account under the Plan and a cash payment
will be made for any fractional Common Share credited to your account under the
Plan. You may again elect to participate in the Plan at any time by calling
1-800-341-2929 or writing to the Trust at:

                              Van Kampen Funds Inc.

(a)      The Trust has adopted a code of ethics (the "Code of Ethics") that
applies to its principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar

a third party.

Item 3.  Audit Committee Financial Expert.

The Trust's Board of Trustees has determined that it has four "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees : J. Miles Branagan, Jerry Choate, R. Craig Kennedy and
Theodore A. Myers. Under applicable securities laws, a person who is determined
to be an audit committee financial expert will not be deemed an "expert" for any
purpose, including without limitation for the purposes of Section 11 of the
Securities Act of 1933, as a result of being designated or identified as an
audit committee financial expert. The designation or identification of a person
as an audit committee financial expert does not impose on such person any
duties, obligations, or liabilities that are greater than the duties,
obligations, and liabilities imposed on such person as a member of the audit
committee and Board of Trustees in the absence of such designation or
identification.

Item 9. Controls and Procedures








(a) The Trust's principal executive officer and principal financial officer have
concluded that the Trust's disclosure controls and procedures are sufficient to
ensure that information required to be disclosed by the Trust in this Form N-CSR
was recorded, processed, summarized and reported within the time periods
specified in the Securities and Exchange Commission's rules and forms, based
upon such officers' evaluation of these controls and procedures as of a date
within 90 days of the filing date of the report.

significant deficiencies or material weaknesses in the Trust's internal controls
or in other factors that could significantly affect the Trust's internal
controls subsequent to the date of their evaluation.

(b) There were no changes in the registrant's internal control over financial
reporting that occurred during the registrant's most recent fiscal half-year
(the registrant's second fiscal half-year in the case of an annual report) that
has materially affected, or is reasonably likely to materially affect, the
registrant's internal control over financial reporting.

Item 10.  Exhibits.

attached hereto.
