CENSUS DATA
In 1990, there were 491,763 foreign-born residents in the Washington DC metro area.
That constituted a population share of 11.9 percent.
CURRENT POPULATION SURVEY (CPS) DATA
The Washington DC metro area, like the District, has a net
out-migration of residents (127,600) that offsets some of the natural increase (390,400 more births than deaths).
The outflow of native residents to other areas is not just a flight from the District, as the metro area has a greater outflow than District alone.
When the focus on net immigration is expanded to the Washington DC metropolitan statistical
area, the population grew by 9 percent - from 4.2
million in 1990 to 4.6 million in 1997. NIM accounted for 172,000 newcomers, or about 45
percent of the population growth. That share attributable to immigration would surely be well
above half of the population increase if the children born here to immigrants were included.
IMMIGRANT SETTLEMENT
The legal immigrant settlement data during this period was augmented by adjustment of status of about 10,000 persons in FY-91
who had been in illegal status until the amnesty that was adopted in the 1986 Immigration
Reform and Control Act (IRCA).
Just among the long-term resident amnesty applicants (excluding the amnestied agricultural
workers), the number of applicants from the Washington, D.C. metro area numbered 19,804.
The Washington, D.C. metropolitan area (MSA) has an even higher concentration of immigrants
than does the District alone. The MSA's foreign-born population in 1990 was nearly 492,000,
giving it a foreign-born share of 11.9%. According to a December 5, 1998 article in the
Washington Post, ("Buying Into the American Dream") the INS says that more than
350,000 immigrants have moved into the region since the early 1980s and the foreign-born share
of the population now is up to one-sixth compared to 1 in 22 in 1970.
INS DATA BY NATIONALITY
The INS data below are furnished for nationals of the countries with the largest number of
immigrants admitted or adjusted to legal residence each year since 1990. The absence of data
means that the total number of admissions to the United States by nationals of that country was
not enough to merit detailed reporting in that year.
The nationalities may change each year, so the totals in some cases will not reflect all the
immigrants of that nationality who have become legal immigrants in the Washington, DC
metro area during this period.
INS data indicate that slightly less than one eighth (14.7%) of the immigrants who intend to
reside in the Washington, DC metro area intend to live in the District. Most are headed for the
Washington suburbs. The nationality group that has the largest share identifying the District as
their residence is from the Dominican Republic (35%). Others that have about one-fifth headed
for the District include immigrants from Vietnam, Nigeria, Jamaica, Haiti, El Salvador and Cuba.
The nationality groups that have the highest shares (over 95%) headed for the suburbs are from
Pakistan, Korea, Iran, and India.

Area.
POPULATION PROJECTION 2025
According to the 2000 Census, the population of the Washington, DC Principal Metropolitan Statistical
Area (PMSA) was 4,922,640. That was a 16.6 percent increase from the 4,223,485 residents in 1990.
The Washington, DC PMSA is comprised of 5 Maryland counties (15.4% population increase 1990-00),
11 Virginia counties and 6 Virginia independent cities (25.1% population increase), 2 West Virginia
counties (24.1% increase) plus the District(5.7% decrease)
During the previous decade, the metro area population increased by 21.4 percent from 3,477,972
in 1980.

The net international migration data understate the impact of immigration on a
locality because they record only the arrival of immigrants from abroad -- not those moving
within the country, and the children born to immigrants after their arrival are not part of the
immigrant settlement data -- they become part of domestic population change.
According to the 1999 CPS, Washington DC's metropolitan area population increased by over
517,000 (12.2%) since
1990. Of that increase, over 240,000 was due to net immigrant settlement (46% of the increase).
This share of population increase does not take into concideration the share of population increase from children of immigrants born in this country --
who are counted with native-born births.
Applying national-level data that show about 21 percent of the country's net increase from natural change results from immigrant births, the total amount of population change in the Washington metro area due to immigration is likely to be about 62 percent.
The Washington DC metropolitan area accounts for
eight times the immigrant settlement rate in the District of Columbia. The annual
average number of immigrants settling in the area since 1990 has been about 29,000.
The data for FY'95, FY'97 and FY'98 were artificially low because the INS did not issue green
cards to all the eligible applicants for adjustment of status who were already in the United
States. In those years, new immigration could have registered as much as 30 percent
higher, if the INS had kept up with its workload.
The current rate of population change between 1990-00, if continued, would result in a population
in 2025 of 7,218,000. That is 46.6 percent larger than the 2000 population.
