HAVE THE PRINCIPLES OF INVESTING CHANGED?
     In a world of frenetic  change in business,  technology,  and the financial
markets,  it is natural to wonder whether the basic principles of investing have
changed.
     We don't think so.
     The most  successful  investors  over the coming  decade  will be those who
began the new century with a fundamental  understanding  of risk and who had the
discipline to stick with long-term investment programs.
     Certainly,  investors  today  confront a challenging,  even  unprecedented,
environment.  Valuations of market  indexes are at or near historic  highs.  The
strength and duration of the bull market in U.S.  stocks have inflated  people's
expectations  and  diminished  their  recognition  of the market's  considerable
risks. And the incredible  divergence in stock returns--many  technology-related
stocks  gained  100% or more in 1999,  yet prices fell for more than half of all
stocks--has made some investors question the idea of diversification.
     And then there is the  Internet.  Undeniably,  it is a powerful  medium for
communications and transacting business.  For investors,  the Internet is a vast
source  of  information  about  investments,  and  online  trading  has  made it
inexpensive and convenient to trade stocks and invest in mutual funds.
     However,  new tools do not guarantee good  workmanship.  Information is not
the same as wisdom.  Indeed,  much of the information,  opinion,  and rumor that
swirl  about  financial  markets  each day  amounts  to  "noise"  of no  lasting
significance.  And the fact  that  rapid-fire  trading  is easy does not make it
beneficial.   Frequent  trading  is  almost  always  counterpro-ductive  because
costs--even at low commission rates--and taxes detract from the returns that the
markets  provide.  Sadly,  many  investors jump into a "hot" mutual fund just in
time to see it  cool  off.  Meanwhile,  long-term  fund  investors  are  hurt by
speculative  trading  activity  because they bear part of the costs  involved in
accommodating purchases and redemptions.
     Vanguard  believes that  intelligent  investors  should  resist  short-term
thinking and focus instead on a few time-tested principles:
o    Invest for the long term. Pursuing your long-term  investment goals is more
     like a marathon than a sprint.
o    Diversify  your  investments  with  holdings  in  stocks,  bonds,  and cash
     investments.  Remember  that,  at any  moment,  some part of a  diversified
     portfolio  will lag  other  parts,  and be wary of  taking  on more risk by
     "piling onto" the  best-performing  part of your  holdings.  Today's leader
     could well be tomorrow's laggard.
o    Step back from the daily frenzy of the markets; focus on your overall asset
     allocation.
o    Capture as much of the market's return as possible by minimizing  costs and
     taxes.  Costs and taxes diminish  long-term  returns while doing nothing to
     reduce the risks you incur as an investor.

REPORT FROM THE CHAIRMAN

[PHOTO JOHN J. BRENNAN]


     Interest rates for most  municipal  bonds  ratcheted  higher during the six
months  ended May 31,  2000--the  first half of Vanguard  New Jersey  Tax-Exempt
Funds' fiscal year--and bond prices  generally  declined.  In this  environment,
municipal bonds earned positive total returns,  as price declines only partially
offset the interest income earned during the period.
     For the half-year,  our Insured  Long-Term  Tax-Exempt  Fund earned a total
return (capital  change plus  reinvested  dividends) of 1.0%, and our Tax-Exempt
Money Market Fund earned 1.7%. As you can see in the adjacent table, the returns
of both funds topped those of their average peers.

*Derived from data provided by Lipper Inc.

     The total  return of the Insured  Long-Term  Tax-Exempt  Fund is based on a
decrease  in net asset  value from $11.19 per share on  November  30,  1999,  to
$11.00 per share on May 31, 2000, and is adjusted for dividends  totaling $0.302
per share paid from net investment  income.  The Tax-Exempt  Money Market Fund's
net asset value remained at $1.00 per share, as was expected but not guaranteed.
     For New Jersey residents, income earned by our funds is exempt from federal
and New  Jersey  income  taxes,  but may be  subject  to local  taxes and to the
alternative minimum tax.
     On May 31, the Insured Long-Term Fund's yield stood at 5.51%, up from 5.07%
at the end of November  1999;  the Money Market Fund's yield was 3.88%,  up from
3.34% six months  earlier.  For  taxpayers  in the  highest  federal  income tax
bracket  (39.6%),  the taxable  equivalent  yields at the end of the period were
about 9.1% for the Insured  Long-Term  Fund and about 6.4% for the Money  Market
Fund.

THE PERIOD IN REVIEW
The U.S. economy expanded  impressively  during the six months ended May 31, but
the terrific  pace of economic  growth  stoked  fears of higher  inflation--and,
thus,  higher  interest  rates.  These fears put  pressure on the prices of both
stocks and bonds,  making it a volatile six months for stocks,  particularly for
technology shares, and a generally lackluster half-year for bonds.
     The Federal  Reserve Board  continued its campaign to head off inflation by
hiking its target  for  short-term  interest  rates by a full  percentage  point
during the  half-year.  The yield of the 10-year  U.S.  Treasury  note rose only
slightly,  to 6.27% on May 31 from  6.19% six months  earlier,  and the yield of
3-month Treasury bills rose by 32 basis points (0.32 percentage  point) to close
the period at 5.62%.  However,  the yield of the benchmark 30-year Treasury bond
fell from 6.29% on November  30, 1999,  to 6.01% on May 31,  2000.  This decline
resulted from the decreasing  supply of

                                       1

<PAGE>

long-term Treasury debt--a development that drove prices higher and yields lower
for the longest-term Treasuries.
     Yields of  high-grade,  long-term  municipal  bonds ended the  half-year at
5.91%,  up a tiny bit from  5.87%  when the period  began.  Yields on  top-grade
(MIG-1) 3-month notes rose 35 basis points to 4.15% on May 31.
     Relative to U.S. Treasury bonds,  longer-term municipal bonds are extremely
attractive, particularly for investors in higher income tax brackets. On May 31,
the yield of a high-grade,  long-term  municipal  bond was equal to about 98% of
the yield of the  30-year  U.S.  Treasury  bond,  whose  interest  is subject to
federal  income tax. The spread between  long-term  Treasury bonds and munis was
unusually  thin  because  of the  heavy  demand  for--and,  thus,  lower  yields
of--long-term Treasuries.  For securities with maturities of 10 years, the yield
of  municipal  bonds  was  equal to about  85% of the  yield  of  Treasuries,  a
proportion in line with the long-term historical rate.
     The U.S. stock market advanced during the six months,  though as the period
progressed  investors' favor shifted toward  value-oriented stocks and away from
growth  shares.  The Wilshire 5000 Total Market  Index,  a measure of the entire
U.S.  stock market,  gained 2.4% for the half-year.  Among  large-capitalization
stocks, the returns of value stocks outpaced those of growth-oriented  shares by
nearly 2  percentage  points  (3.6% for the  Standard & Poor's  500/BARRA  Value
Index;  1.9% for the S&P  500/BARRA  Growth  Index).  The split  was  especially
evident from March  through May,  when large value stocks gained 10.0% and large
growth stocks slipped -0.4%.

PERFORMANCE OVERVIEW
Vanguard New Jersey Tax-Exempt Money Market Fund earned 1.7% for the six months,
just ahead of the 1.6% return of our average  peer.  Our margin over our average
competitor  can be  attributed  to our  much  lower  expenses,  which  give us a
significant  and  sustainable  advantage  over  funds  that  invest  in  similar
securities.
     The 1.0% total  return  earned by the  Insured  Long-Term  Tax-Exempt  Fund
during the  half-year  exceeded  the return  achieved  by our  average  peer and
matched that of the Lehman Brothers  Municipal Bond Index,  which exists outside
the real world of operating expenses and transaction costs.
     Of course, a six-month return tells only part of the story of a bond fund's
performance.  It's  important  to note that  semiannual  returns  for bond funds
account for only half of the year's  interest  income,  while  prices  fully and
immediately  reflect  movements  in interest  rates--rising  when rates fall and
falling  when rates rise.  For  perspective,  it's  important to consider a full
year's interest  income when evaluating a bond fund.  During the 12 months ended
May 31, 2000, our Insured  Long-Term  Tax-Exempt  Fund recorded a negative total
return of -1.4%,  consisting  of an income return of 5.1% and a price decline of
-6.5%.
     Also, keep in mind that rising  interest rates,  which cause bond prices to
fall, are not entirely bad news for fixed income investors.  Money market yields
and returns quickly adjust higher.  And for long-term  bonds, a rise in interest
rates  causes an  immediate  price  decline,  but the  long-term  effect  can be
beneficial   because  there  is  more  income  to  reinvest  at  higher  yields.
Conversely, when interest rates drop, bond prices rise immediately, but over the
long haul, lower rates diminish the income earned on reinvested dividends.
     Though bond prices can swing dramatically, over the long run it is interest
income that accounts for  virtually all of a bond fund's total return.  As such,
municipal  bonds  that  now  offer a yield of about  5.5%  can  provide  a solid
long-term return, particularly if inflation remains at relatively low levels.

                                       2
<PAGE>

     A key  ingredient in our success is our  significant  cost  advantage  over
similar  funds.  Our  funds  have  annualized  expense  ratios  (expenses  as  a
percentage  of average  net  assets)  of about  0.20%,  compared  with the 1.01%
charged  by the  average  long-term  New  Jersey  tax-exempt  fund and the 0.66%
charged  by the  average  New  Jersey  tax-exempt  money  market  fund.  For our
shareholders, the benefits of low costs are twofold. Our cost advantage provides
us with a head start in our quest to  outperform  our  competitors.  Lower costs
also allow our investment adviser,  Vanguard Fixed Income Group, to select bonds
with higher credit  quality than those chosen by our peers,  without a sacrifice
in net yields.
     For Vanguard New Jersey  Insured  Long-Term  Tax-Exempt  Fund,  our adviser
invests primarily in bonds that carry private insurance guaranteeing the payment
of principal  and interest in the event that a bond issuer  defaults on its debt
obligations.  Though these  securities  offer  slightly  lower gross yields than
noninsured  bonds,  our  low  costs  historically  have  more  than  made up the
difference,  allowing our fund to provide net returns that are fully competitive
with those of lower-quality municipal bond portfolios.

IN SUMMARY
The argument for holding  bonds as well as stocks in a balanced  portfolio is an
enduring one that is not based on past returns or projections of future returns.
Fixed income  investments  add to a  portfolio's  diversification,  and interest
income is a valuable and durable component of total return that, when compounded
over long  periods,  plays an important  role in  accumulating  wealth.  For New
Jersey residents, the triple tax benefit of a New Jersey municipal bond fund can
be especially valuable.
     History has taught us that  investors who maintain  balanced  portfolios of
well-diversified  stock funds, bond funds, and money market funds generally find
it easier to maintain their  equilibrium in turbulent times. We urge you to base
your investment plans on your own goals, time horizon,  and risk  tolerance--and
then to stick with those plans over the long haul.

IN MEMORY
--------------------------------------------------------------------------------
It is with  great  sadness  that I  report  the  death  of John C.  Sawhill,  an
independent  trustee of the fund and a member of The Vanguard  Group's  board of
directors  since 1991.  John, an economist who was president and chief executive
officer  of The  Nature  Conservancy,  died on May 18 at age 63. He was a senior
lecturer at the Harvard  Business School and had formerly served as president of
New York  University  and as deputy  secretary of the U.S.  Department of Energy
under President Jimmy Carter.  John was a remarkable man who was full of energy,
vigor,  and life. His experience and wisdom added a great deal to Vanguard,  and
his death is a blow to everyone  who knew and loved him.  Though  John's work on
behalf of our funds was often  carried on behind the scenes,  he was a dedicated
advocate for the best interests of our shareholders. He will be missed.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED MAY 31, 2000
Strong  crosscurrents  pushed and  tugged at  financial  markets  during the six
months ended May 31, 2000.  Positive  influences  included very strong  economic
growth and rising corporate profits.  Negative factors included tighter monetary
policy, higher inflation, and concerns about stock valuations.
     Interest  rates rose in most  segments of the bond market,  and bond prices
slipped. Stock prices rose slightly, on balance,  although wide day-to-day price
swings were frequent.
     Uncertainty  in both the bond and stock markets  centered on the surprising
performance of the U.S.  economy,  which grew at a torrid 7.3% pace in the final
three  months of 1999 and at a  still-robust  5.4%  during the first  quarter of
2000.  With U.S.  unemployment  at around  4.0% of the  workforce,  the  Federal
Reserve Board  continued to be concerned that inflation  would worsen unless the
economic  expansion  slowed.  The Fed raised  short-term  interest rates by 0.25
percentage  point in February and again in March,  before boosting rates by 0.50
percentage    point    in    mid-May.    These    boosts,     following    three
quarter-percentage-point increases in 1999, took the Fed's target for short-term
rates to 6.5%.  By the end of May,  some  signs of  slowing  had  emerged in the
economy,  although it was not certain  that the Fed had  finished  applying  the
brakes.
     Evidence on inflation was  ambiguous.  The Consumer  Price Index  increased
1.8% and 3.1%, respectively, for the six- and twelve-month periods ended May 31,
but  much of the  increase  was due to  higher  energy  and  food  prices.  Core
inflation,  which excludes those  sectors,  was up a less-scary  2.4% during the
twelve months ended May 31.

U.S. STOCK MARKETS
Optimism about long-term prospects for technology, media, and telecommunications
companies  dominated  the equity  markets  through the first three months of the
period.  But  sentiment  shifted  suddenly  in  mid-March,  sending the tech and
telecom  groups  sharply  lower.  The tech-heavy  Nasdaq  Composite  Index,  for
example, registered a 41.1% return from November 30 through February 29, only to
give back most of the gains  over the next  three  months.  End  result:  a 2.4%
return for the six months ended May 31.
     The overall  stock  market,  as measured by the Wilshire  5000 Index,  also
returned 2.4%.  Value stocks,  those  characterized  by  above-average  dividend
yields and below-average  price/earnings and price/book value ratios,  enjoyed a
resurgence beginning in mid-March.

                                       4

<PAGE>


For the full six months,  the value components of both the  large-capitalization
S&P 500 Index and the  small-cap  Russell 2000 Index  outperformed  the indexes'
growth components.
     Within the S&P 500, the  half-year's  best return was the 48% gain recorded
by "other energy" stocks,  including  oil-drilling  and services  companies that
benefited from a continuing  rise in oil prices.  The  producer-durables  sector
gained  18%,  largely  because  of big gains for a number  of  manufacturers  of
telecommunications  gear and  semiconductor  testing and fabrication  equipment.
Technology  stocks,  which now account for about  one-quarter of the total stock
market's value, gained about 12% for the six months.
     Poor performers included the utilities sector (-14% return), which was hurt
by downturns in several large telephone stocks,  and many consumer staples (-9%)
and consumer-discretionary  (-6%) companies. Prices fell steeply for a number of
high-profile  retailers,  beverage  and  food  makers,  tobacco  companies,  and
entertainment enterprises.

U.S. BOND MARKETS
The Federal  Reserve's  influence on interest  rates is strongest for short-term
securities. Over the six months, the Fed pushed up the rate charged on overnight
loans  between  banks by 1  percentage  point to 6.5%.  Yields of  3-month  U.S.
Treasury bills rose only one-third as far (0.32  percentage  point,  or 32 basis
points),  to 5.62%.  And long-term  Treasury yields moved even less. The 10-year
Treasury  note rose just 8 basis  points to 6.27% as of May 31, and yields  fell
for very long-term  Treasury bonds due to a cutback in issuance of new bonds. As
a result of the shrinking  supply of long-term  bonds,  the yield of the 30-year
Treasury  bond  declined  28  basis  points--from  6.29%  to  6.01%--during  the
half-year.
     Because short-term rates moved higher while long-term rates declined, there
was an unusual "inversion" in the yield curve.  Instead of sloping  upward--with
yields  increasing  along with the  maturity of Treasury  securities--the  curve
sloped down. The 6.01% yield of 30-year Treasuries on May 31 was 70 basis points
below the 6.71% yield on 3-year Treasury notes.
     Corporate  and  municipal  bonds  did  not  perform  as  well  as  Treasury
securities,  and the yield curve for these sectors remained  positive--yields of
long-term bonds remained higher than those of short-term securities.  The Lehman
Aggregate  Bond Index,  a proxy for the overall  taxable bond  market,  returned
1.4%, as a price decline of 2% offset most of the 3.4% income  provided by bonds
during the half-year.


INTERNATIONAL STOCK MARKETS
A stronger  U.S.  dollar and weak Asian  markets made the half-year a lackluster
one for U.S.  investors in foreign stocks.  Improving economic growth in most of
the world  helped a number of  markets  in Europe,  Asia,  and Latin  America to
produce good gains in their local currencies. However, the U.S. dollar increased
in value versus most currencies,  significantly reducing the returns received by
dollar-based  investors.  (Conversely,  when the dollar falls in value,  returns
from abroad are enhanced for U.S. investors.)
     The overall  return in dollars from developed  foreign  markets was a scant
0.7%,  as  measured  by  the  Morgan  Stanley  Capital   International   Europe,
Australasia, Far East (EAFE) Index. However, in local currencies, the EAFE Index
return for the six months was a very respectable 7.8%.
     In  Europe,   where  stocks  benefited  from  a  continuance  of  corporate
acquisitions,  an average 12.8% gain in local-currency terms was reduced to 4.7%
for U.S.  investors  because of the  dollar's  strength.  Stocks in the  Pacific
region,  which is  dominated  by Japan,  returned  -7.0% in dollars,  as a -2.0%
return in local-currency terms was further diminished by the dollar's gains. The
Select Emerging Markets Free Index returned -2.8% in U.S. dollars.

REPORT FROM THE ADVISER

The economy  continued its robust  expansion during the six months ended May 31,
2000,  the first  half of the fiscal  year for  Vanguard  New Jersey  Tax-Exempt
Funds.  The  unemployment  rate fell as low as 3.9% and the  economy  grew at an
annual rate of more than 5% during the half-year.
     A fear of  inflation  roiled the markets,  as  investors  focused on rising
short-term  rates.  On three  occasions the Federal  Reserve Board increased the
federal funds rate to slow economic  growth.  In turn,  this led to a noticeable
increase in stock market volatility.  Throughout the tumult, the tax-exempt bond
market remained  relatively calm. A typical  long-term,  high-quality  municipal
bond  started the period  with a 5.87% yield and ended it with a barely  changed
yield of 5.91%.  Importantly,  the  transition  from 1999 to 2000 went smoothly,
without  negative  effects  for either the  issuers  of  municipal  bonds or the
financial markets.
     Although other markets were volatile during the half-year, tax-exempt bonds
were a solid, if unglamorous,  investment, and your funds continued to dutifully
turn out consistent tax-exempt dividends.  Often the municipal securities market
lacks the dramatic allure of the stock market.  However,  tax-exempt  securities
are a reliable workhorse for the total return of an investor's portfolio.
     The  Tax-Exempt  Money Market Fund earned a tax-free  return of 1.7% during
the  half-year,  while the Insured  Long-Term  Tax-Exempt  Fund  provided a 1.0%
return. Each fund outpaced the average return for its peer group of funds.

LOW DEMAND, LOW SUPPLY
During the  half-year,  few new  investors  entered the  municipal  bond market.
Indeed,  most  tax-exempt  funds  experienced net outflows of cash, as investors
redeemed shares to finance other purchases or to pay federal taxes.  During this
time,  the low demand for  municipal  bonds  improved  their  value  relative to
taxable bonds. As of May 31, a highly rated,  long-term state general obligation
bond provided 98% of the income of a similar U.S. Treasury security, even though
interest paid on the municipal bond is generally exempt from federal income tax,
while interest on Treasuries is not. Investors in the top (39.6%) federal income
tax bracket,  therefore,  received 2.3  percentage  points in additional  yield,
after  taxes,  from  high-quality,   long-term  muni  bonds  than  from  similar
Treasuries. Such attractive relative yields have rarely endured.
     The supply of newly issued  tax-exempt bonds so far in 2000 is a staggering
30% lower than last year. The stronger economy has boosted the finances of local
governments,  so fewer issuers need to tap the credit  markets.  The drop in new
municipal bond issuance has supported prices for existing tax-exempt securities,
especially in states with relatively high taxes. However, the effects of reduced
supply have  largely been offset by tepid demand for  municipal  bonds.  At some
point,  we can expect  that muni bond  prices  will rise in relation to those of
taxable bonds and that the spread between yields of municipals and taxable bonds
will widen.


================================================================================
INVESTMENT PHILOSOPHY
The adviser  believes that each fund, while operating within stated maturity and
stringent  quality  targets,  can achieve a high level of current income that is
exempt from  federal and New Jersey  income  taxes by  investing  in insured and
high-quality  uninsured  securities  issued by New  Jersey  state,  county,  and
municipal governments.

MATURITY SPREADS NARROW, CREDIT SPREADS WIDEN
For municipal bonds, as for other fixed income investments, the spread in yields
between  issues  with  short- and  long-term  maturities  has  narrowed.  In the
tax-exempt market, the gap in yields between a 1-year bond and a 30-year bond is
only 1.4  percentage  points,  down from  about 2.0  percentage  points.  In the
Treasury bond market,  short-term  yields are  currently  higher than yields for
long-term bonds.  This is unusual,  because  investors  typically require higher
yields to lend  money for longer  periods.  The  anomaly  reflects  the  Federal
Reserve Board's raising of short-term  rates and the fall in supply of long-term
Treasury bonds.  Even if the Fed keeps raising  interest rates, we expect yields
for tax-exempt bonds to maintain their usual  upward-sloping  curve, with yields
rising as maturities increase.
     During the half-year,  the spread between yields of high-quality  municipal
bonds and yields of lower-quality  bonds widened.  This meant that lower-quality
bond prices lagged those of high-quality bonds and that investors were demanding
higher yields to take on higher credit risk. During the period, the extra income
paid by bonds with the lowest  investment-grade  rating  (Baa/BBB)  versus those
with the highest  quality (AAA)  increased from 0.50 to 0.75  percentage  point.
This  reversed  the trend of recent  years,  when  credit  spreads  narrowed  to
historical  lows as investors  stretched  for  incrementally  higher  returns by
buying lower-quality bonds.
     The trend  toward  wider  credit-quality  spreads  began with bonds used to
finance  hospitals and other health care facilities.  Most health care providers
have credit  ratings in the middle or lower tiers of  investment-grade  ratings.
Rising  cost  pressures  and  reductions  in expense  reimbursement  from health
insurers  have taken a toll.  Investors  are cautious and have  demanded  higher
yields to hold bonds from these issuers,  a trend that has spilled over into all
lower-quality  sectors.  As you have come to expect,  Vanguard has  maintained a
steady commitment to  higher-quality  issues. We have sought to provide superior
income by keeping expenses low, so that more of the funds' gross income flows to
you,  rather than by taking on increased  credit risk. The market's recent focus
on credit quality has helped our performance relative to peer funds.

THE TAX-EXEMPT MONEY MARKET FUND
The yield on the 1-year U.S.  Treasury  bill rose 49 basis  points to finish the
period at 6.17%.  This rise was a direct  result of the  earlier-mentioned  rate
hikes by the Fed. Yields on 1-year  tax-exempt money market  instruments rose 72
basis points during the six months.  The benchmark  1-year MIG-1 tax-exempt note
closed the period with a yield of 4.59%.  Short-term municipal securities became
more  attractive  relative to  Treasuries:  The ratio of yields of 1-year  MIG-1
notes to those of 1-year  Treasuries  increased during the six months from 68.1%
to 74.4%.  Contributing  to the rise in yields for  short-term  municipals was a
surge in redemptions  from tax-exempt  money market funds during tax season,  as
shareholders wrote checks to pay their federal tax liabilities.

AVERAGE COUPON. The average interest rate paid on the securities held by a fund.
It is expressed as a percentage of face value.

AVERAGE  DURATION.  An  estimate  of how much a bond  fund's  share  price  will
fluctuate in response to a change in interest  rates. To see how the price could
shift,  multiply the fund's  duration by the change in rates.  If interest rates
rise by one percentage point, the share price of a fund with an average duration
of five years  would  decline  by about 5%. If rates  decrease  by a  percentage
point, the fund's share price would rise by 5%.

AVERAGE  MATURITY.  The average  length of time until bonds held by a fund reach
maturity  (or are  called) and are  repaid.  In general,  the longer the average
maturity, the more a fund's share price will fluctuate in response to changes in
market interest rates.

AVERAGE QUALITY.  An indicator of credit risk, this figure is the average of the
ratings assigned to a fund's securities holdings by credit-rating  agencies. The
agencies make their  judgment after  appraising an issuer's  ability to meet its
obligations.  Quality is graded on a scale,  with Aaa or AAA indicating the most
creditworthy  bond  issuers and A-1 or MIG-1  indicating  the most  creditworthy
issuers of money market securities.

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and downs of the  overall  market  (or  appropriate  market
index).  The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20  would have seen its share  price  rise or fall by 12% when the  overall
market rose or fell by 10%.

CASH  RESERVES.  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  to simulate  bond
investment.

DISTRIBUTION BY CREDIT QUALITY.  This breakdown of a fund's securities by credit
rating can help in gauging the risk that  returns  could be affected by defaults
or other credit problems.

DISTRIBUTION  BY MATURITY.  An indicator of interest rate risk. In general,  the
higher the  concentration  of  longer-maturity  issues,  the more a fund's share
price will fluctuate in response to changes in interest rates.

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.

INVESTMENT  FOCUS.  This  grid  indicates  the  focus  of a fund in terms of two
attributes: average maturity (short, medium, or long) and average credit quality
(high, medium, or low).

NUMBER OF ISSUES.  An indicator of  diversification.  The more separate issues a
fund holds,  the less  susceptible  it is to a price  decline  stemming from the
problems of a particular issue.

R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
return  were  precisely  synchronized  with the  overall  market's  return,  its
R-squared  would  be 1.00.  If a  fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.

YIELD.  A  snapshot  of a fund's  interest  income.  The yield,  expressed  as a
percentage  of the fund's net asset  value,  is based on income  earned over the
past 30 days (7 days for money  market  funds) and is  annualized,  or projected
forward for the coming year.

YIELD  TO  MATURITY.  The  rate of  return  an  investor  would  receive  if the
securities held by a fund were held to their maturity dates.

FINANCIAL STATEMENTS
MAY 31, 2000 (UNAUDITED)

STATEMENT OF NET ASSETS
This Statement  provides a detailed list of each fund's municipal bond holdings,
including each security's  market value on the last day of the reporting  period
and  information  on credit  enhancements  (insurance  or  letters  of  credit).
Securities are grouped and  subtotaled  according to their insured or noninsured
status.  Other assets are added to, and  liabilities  are  subtracted  from, the
value of Total Municipal Bonds 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 on both a dollar and per-share  basis.
Undistributed Net Investment Income is usually zero because the fund distributes
its net income to  shareholders  as a dividend each day. Any realized gains must
be distributed  annually,  so the bulk of net assets consists of Paid in Capital
(money invested by shareholders). The balance shown for Accumulated Net Realized
Gains usually approximates the amount available to distribute to shareholders as
taxable  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 realized  gains,  will appear as negative  balances.
Unrealized  Appreciation  (Depreciation) is the difference  between the 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 OPERATIONS
This Statement shows interest  earned by each fund during the reporting  period,
and details the operating  expenses charged to the fund. These expenses directly
reduce the amount of  investment  income  available  to pay to  shareholders  as
tax-exempt  income  dividends.  This  Statement  also shows any Net Gain  (Loss)
realized  on the  sale of  investments,  and the  increase  or  decrease  in the
Unrealized  Appreciation  (Depreciation) on investments  during the period. If a
fund  invested  in futures  contracts  during the  period,  the results of these
investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS
This  Statement  shows how each fund's total net assets  changed  during the two
most recent reporting periods.  The Operations  section  summarizes  information
detailed in the Statement of Operations. Because the fund distributes its income
to shareholders  each day, the amounts of  Distributions--Net  Investment Income
generally equal the net income earned as shown under the Operations section. The
amounts of Distributions--Realized  Capital Gain may not match the capital gains
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 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,  and the amounts  redeemed.  The corresponding
numbers of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS
This table  summarizes  each  fund's  investment  results and  distributions  to
shareholders on a per-share  basis. It also presents the fund's 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.  Money market  funds are not  required to report a Portfolio  Turnover
Rate.

NOTES TO FINANCIAL STATEMENTS
Vanguard New Jersey  Tax-Exempt  Funds comprise the New Jersey  Tax-Exempt Money
Market Fund and the New Jersey Insured Long-Term  Tax-Exempt Fund, each of which
is registered under the Investment Company Act of 1940 as an open-end investment
company,  or mutual  fund.  Each fund invests in debt  instruments  of municipal
issuers whose ability to meet their  obligations may be affected by economic and
political developments in the state of New Jersey.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles  for mutual  funds.  The funds  consistently  follow such
policies in preparing their financial statements.
     1. SECURITY VALUATION:  Tax-Exempt Money Market Fund: Investment securities
are valued at amortized cost, which approximates market value. Insured Long-Term
Tax-Exempt Fund: Bonds, and 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.  Securities  for which  market  quotations  are not
readily  available  are valued by  methods  deemed by the board of  trustees  to
represent fair value.
     2.  FEDERAL  INCOME  TAXES:  Each fund  intends to continue to qualify as a
regulated investment company and distribute all of its income.  Accordingly,  no
provision for federal income taxes is required in the financial statements.
     3.  FUTURES  CONTRACTS:  The  Insured  Long-Term  Tax-Exempt  Fund  may use
Municipal  Bond Index,  U.S.  Treasury  Bond,  and U.S.  Treasury  Note  futures
contracts,  with the  objectives of enhancing  returns,  managing  interest rate
risk,   maintaining   liquidity,   diversifying   credit  risk,  and  minimizing
transaction  costs. The fund may purchase or sell futures  contracts  instead of
bonds to take advantage of pricing  differentials  between the futures contracts
and the  underlying  bonds.  The fund may also seek to take  advantage  of price
differences  among bond  market  sectors by  simultaneously  buying  futures (or
bonds) of one market  sector and selling  futures (or bonds) of another  sector.
Futures  contracts may also be used to simulate a fully invested position in the
underlying  bonds while  maintaining a cash balance for  liquidity.  The primary
risks  associated  with the use of futures  contracts are imperfect  correlation
between  changes  in market  values of bonds  held by the fund and the prices of
futures contracts, and the possibility of an illiquid market.
     Futures  contracts  are valued  based upon their  quoted  daily  settlement
prices. The aggregate principal amounts of the contracts are not recorded in the
financial statements. Fluctuations in the value of the contracts are recorded in
the  Statement  of Net Assets as an asset  (liability)  and in the  Statement of
Operations as  unrealized  appreciation  (depreciation)  until the contracts are
closed, when they are recorded as realized futures gains (losses).
     4.  DISTRIBUTIONS:  Dividends from net investment income are declared daily
and paid on the first business day of the following month. Annual  distributions
from realized capital gains, if any, are recorded on the ex-dividend date.
     5. OTHER:  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. Premiums and
original issue discounts are amortized and accreted,  respectively,  to interest
income over the lives of the respective securities.

NOTES TO FINANCIAL STATEMENTS (continued)

B.  The  Vanguard  Group  furnishes  at  cost  investment  advisory,   corporate
management,  administrative,  marketing, and distribution services. The costs of
such services are allocated to each fund under methods  approved by the board of
trustees.  Each fund has  committed  to provide up to 0.40% of its net assets in
capital  contributions  to Vanguard.  At May 31, 2000, the funds had contributed
capital to Vanguard (included in Other Assets) of:

--------------------------------------------------------------------------------
                            CAPITAL CONTRIBUTION    PERCENTAGE    PERCENTAGE OF
                                TO VANGUARD           OF FUND      VANGUARD'S

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


The funds' trustees and officers are also directors and officers of Vanguard.

C. The funds'  investment  adviser  may direct new issue  purchases,  subject to
obtaining  the best price and  execution,  to  underwriters  who have  agreed to
rebate or credit to the funds  part of the  underwriting  fees  generated.  Such
rebates  or  credits  are used  solely  to  reduce  the  funds'  management  and
administrative expenses. The funds' custodian bank has also agreed to reduce its
fees when the  funds  maintain  cash on  deposit  in their  non-interest-bearing
custody  accounts.  For the six months  ended May 31, 2000,  these  arrangements
reduced expenses by:

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

D. During the six months ended May 31, 2000,  the Insured  Long-Term  Tax-Exempt
Fund  purchased  $72,143,000 of investment  securities  and sold  $86,947,000 of
investment securities, other than temporary cash investments.

E. Capital gain  distributions are determined on a tax basis and may differ from
realized  capital gains for financial  reporting  purposes due to differences in
the timing of realization of gains.  The Insured  Long-Term  Tax-Exempt Fund had
realized  losses  totaling  $2,044,000  through  November  30,  1999,  which are
deferred for tax purposes and reduce the amount of  unrealized  appreciation  on
investment  securities  for tax purposes (see Note F). At November 30, 1999, the
fund had available capital losses of $782,000 to offset future net capital gains
through November 30, 2007.

F. At May 31, 2000, net unrealized  depreciation of Insured Long-Term Tax-Exempt
Fund  investment  securities  for federal  income tax purposes was  $15,626,000,
consisting of unrealized  gains of $20,768,000  on securities  that had risen in
value since their  purchase  and $36,394 ,000 on  securities  that had fallen in
value since their purchase (see Note E).

     At May 31, 2000, the aggregate  settlement value of open futures  contracts
expiring   in   September   2000  and  the   related   unrealized   appreciation
(depreciation) were:
