Northern Virginia town income, economically disadvantage populations, and more demographics, data and graphs. Analyzed by the Northern Virginia Regional Commission (NVRC). Median Household Income of Towns Reports, maps, and charts are best viewed on a desktop or tablet. Median Household Income of Towns Northern Virginia is known for having communities with some of the highest median incomes in the United States, including the county with the highest in the nation. High median household incomes coincide with the large, thriving business community of the Northern Virginia region. While the median household income is high, it must be recognized that there are segments of the community in need of assistance that live in this prosperous region of the country and that high housing costs offset the high income when it comes to standards of living and well-being. Median Household Income - Current The median household income of the counties, cities, and incorporated towns in Northern Virginia is shown in this graph. Loudoun County is the number one ranked county (county equivalent) for median household income in the nation. The towns of Clifton and Vienna have estimated median household incomes even greater than Loudoun County. All Northern Virginia counties, cities, and towns, have a median household income higher than Virginia, except for the Towns of Dumfries and Quantico. Quantico is the only locality in Northern Virginia with a median household income lower than the nation. Median Household Income - Historic Compared to Current Note, the American Community Survey is a survey with a small sample size. Due to the small population of many towns, the median household income of towns for should be used with caution and the margin of error of the median household income should be taken into consideration. If there is a large increase or decrease in the estimate from one time period to the next, and the margin of error is large and overlaps other periods, then the large change between time periods is likely due to statistical sampling error and the data should be used with caution. The margin of error is shown in the popup that is displayed when hovering over a bar in the bar charts. In addition to the margin of error, the accuracy of the American Community Survey data for an area can be gaged by evaluating the trend. If the data does not have a clear trend, and the margin of error is large and overlaps other periods, then the large change between time periods is likely due to statistical sampling error and the data should be used with caution.

Northern Virginia educational attainment, public school student enrollment, and more demographics, data and graphs by region and county. Analyzed by the Northern Virginia Regional Commission (NVRC). Educational Attainment Overall Reports, maps, and charts are best viewed on a desktop or tablet. Educational Attainment of Northern Virginia Overview Northern Virginia localities are home to some of the most highly educated residents in the nation. This high education level of the region's citizens creates a strong, flourishing business community. The percentage of Northern Virginia's population age 25 or more holding a bachelor's or higher degree is 61.9%, which is nearly double the United States, and holding a graduate or professional degree is 30.2%, which is more than double the United States. About the Data and Proper Data Interpretation Educational attainment data is sourced from the U.S. Census Bureau 2000 Census and the American Community Survey (ACS). It is important to note that any data sourced from the ACS is based on a small sample of the population of a place. Areas with smaller populations, such as the cities of Northern Virginia, may have a larger margin of error in the data due to the survey sample size being small. This is less of an issue the larger the population. The margin of error is shown in the popup that is displayed when hovering over a bar in the bar charts. If there is a large increase or decrease in the estimate from one time period to the next, and the margin of error is large and overlaps other periods, then the large change between time periods is likely due to statistical sampling error and is not considered statistically significant. In addition to the margin of error, the accuracy of the American Community Survey data for an area can be gaged by evaluating the trend. If the data has a clear trend then the data from one period to the next can be deemed reliable.

Northern Virginia population growth, minority-majority transition, foreign born population transformation, and more demographics, data and graphs by region and county. Analyzed by the Northern Virginia Regional Commission (NVRC). Population Overall Reports, maps, and charts are best viewed on a desktop or tablet. Population of Northern Virginia Overview Northern Virginia is on the front lines of a demographic transformation shaping the United States. There has been an extraordinary amount of population growth in Northern Virginia. In 2025, the Northern Virginia population was 79% more than in 1990 when the population was 1,466,350. Population Estimate 2025 2,628,004 Annual Estimates/Trends Decennial Census/Trends Annual Estimates Annual Estimates: Population, Natural Change (Births and Deaths), Migration Annual estimates of population and the components of change (domestic migration, international migration, births, and deaths) paint a portrait of the annual growth patterns in the towns of Northern Virginia. Annual estimates are not based on a full census of the population. Rather, they are estimates based on a compilation of multiple administrative data pieces such as birth records and residential building permits. The estimates are obtained from the U.S. Census, which benchmarks estimates to the Decennial Censuses. Decennial Census data represents the population as of April 1 of the year, whereas the annual estimates are as of July 1 of each year. Decennial Population Decennial Census Data: Population The Decennial Census is based on a survey of the entire population. It is conducted once a decade. The 2020 Decennial Census population was released on August 12, 2021. The Decennial Census regional, county, and city population data is shown in the interactive charts that follow. Key Facts: Decennial Growth In 2020, Northern Virginia's population was 2,550,337 according to the Decennial Census. The population increased from 1,466,409 in 1990, a 74% increase in the 30 year period from 1990 to 2020. Northern Virginia added approximately 320,000 people in this past decade, 2010 to 2020. This is 96,000 or 23% less than the previous decade, signaling a significant slowdown in the pace of growth. However, growth still continues at a high amount. Virginia’s population grew by 630,369 from 2010 to 2020, of which 50.7% of that growth was in Northern Virginia. In 2020, 29.5% of Virginia’s population was in Northern Virginia, compared to 27.9% in 2010. Growth peaked in 2010. Growth in Northern Virginia has slowed since 2010. It has trended down annually since 2010, but it is still large and impactful growth that the the region is facing. The localities in Northern Virginia the growth is occurring in this decade is different in some ways than in the 1990s and 2000s. The preponderance of population growth of Northern Virginia continues to be located in the outer-ring suburbs of Prince William, Loudoun Counties, and the Cities of Manassas and Manassas Park. However, the share of the region's growth that is in the outer-ring has dropped from 65.1% in the 2000 to 2010 period to 61.5% in the 2010 to 2020 period. Arlington has seen its share of the region's growth more than double from what it experienced in the 2000's. Alexandria has seen its share of the region's growth become 2.2 times what it experienced in the 2000's. Intensification of developmental pressures this decade in the inner-core is a response to the millennial generation preferences, demographics, urbanization, transportation and other market pressures.

Northern Virginia population growth, minority-majority transition, foreign born population transformation, and more demographics, data and graphs by region and county. Analyzed by the Northern Virginia Regional Commission (NVRC). Foreign Born and Immigrants Overall Reports, maps, and charts are best viewed on a desktop or tablet. Foreign Born and Immigrant Population of Northern Virginia Overview The Washington, D.C. metropolitan area is one of the most diverse in the country when taking into consideration the racial, ethnic, and foreign born (immigrant) population make-up. Northern Virginia contains a sizable amount of the metropolitan area's diverse population. The foreign born or immigrant population is transforming the region. Note, the terms foreign born and immigrant are used interchangeably throughout the NOVA Region Dashboard. Immigration has been driving demographic transformations in the region , including: School enrollment changes Sizable increases in the number of Hispanics and Asians Population growth Employment growth About the Data and Proper Data Interpretation Foreign born population data is sourced from the U.S. Census Bureau 2000 Census and the American Community Survey (ACS). It is important to note that any data sourced from the ACS is based on a small sample of the population of a place. Areas with smaller populations, such as the cities of Northern Virginia, may have a larger margin of error in the data due to the survey sample size being small. This is less of an issue the larger the population. The margin of error is shown in the popup that is displayed when hovering over a bar in the bar charts. If there is a large increase or decrease in the estimate from one time period to the next, and the margin of error is large and overlaps other periods, then the large change between time periods is likely due to statistical sampling error and is not considered statistically significant. In addition to the margin of error, the accuracy of the American Community Survey data for an area can be gaged by evaluating the trend. If the data has a clear trend then the data from one period to the next can be deemed reliable. Foreign Born Population - Current Foreign Born Population Share - Current Five-Year Estimates All jurisdictions in the United States are included in the five-year American Community Survey estimates. The share of the population that is foreign born, for all jurisdictions in Northern Virginia, is displayed in this graph. Northern Virginia's foreign born population share is 28.2%, which is on par with New York County, New York (Manhattan). All of Northern Virginia jurisdiction's have a foreign born population share that is greater than the Commonwealth of Virginia and the United States. Out of all 3,144 jurisdictions in the USA, all Northern Virginia jurisdictions are ranked #165 or higher. The region's highest ranked are Manassas Park City (8th), Manassas City (21st), Fairfax County (24th), and Fairfax City (25th), each of which have a greater foreign born population share than New York County, New York (Manhattan) (28.2% and 39th) and Orange County, California (30.4% at 28th). Foreign Born Population Share - Current One-Year Estimates Those jurisdictions with a population of 65,000 or more are included in the one-year American Community Survey estimates. The share of the population that is foreign born for the five largest jurisdictions in Northern Virginia are shown in this graph. The Northern Virginia foreign born figures for the one-year estimates are representative of the five largest jurisdictions in Northern Virginia only. The regional foreign born population share is 28.5%. This is greater than New York County, New York (Manhattan) (27.9%), and only 3.1 percentage points less than Orange County, California (31.6%). All of Northern Virginia's five largest jurisdictions have a foreign born population share that is significantly greater than the Commonwealth of Virginia and the United States. Out of the 850 jurisdictions with a population of 65,000 or more in the USA, all of Northern Virginia's large jurisdictions are ranked in the top fifty. The Counties of Fairfax and Loudoun have a share that is greater than Manhattan. Foreign Born Population - Historic Compared to Current Foreign Born Population Share - Historic Compared to Current Five-Year Estimates Immigration has been driving many of the major demographic shifts in the region. Northern Virginia's population was 21.4% foreign born in 2000 and has risen to 28.2% in the 2020-2024 period. Similar to today, back in 2000 all Northern Virginia jurisdictions had a foreign born population share that was greater than the Commonwealth of Virginia and the United States. The greatest transformations have occurred in the four outer-core jurisdictions of Loudoun, Manassas City, Manassas Park, and Prince William. The outer-core of the region also accounts for a majority of the region's overall population growth, as indicated in the population growth charts . Foreign Born Population Share - Historic Compared to Current One-Year Estimates The foreign born population trend, for the regions large jurisdictions (population of 65,000 or more), is shown in the following graphs. The legal status of non-citizens is unknown and not collected by the U.S. Census Bureau in any of its data sets. Key Facts: Northern Virginia, as defined for this analysis using the region's five largest jurisdictions, experienced an increase in the foreign born population and the share from 2011 to 2017. The foreign born population share increased from 25.5% to 28.6% respectively. From 2017 to 2021 it trended down, reaching a low of 27.2% in 2021. The decline from 2017 to 2021 was attributable to the 2017 to 2021 presidential administration's reforms to immigration policy, as well as the coronavirus pandemic. The pandemic led to a drop in the region's population between 2020 and 2021 because of out-migration of residents, elevated death rates, and slowing immigration As the pandemic eased in 2022 and the 2021 to 2025 presidential administration implemented less restrictive immigration policies, both national and regional immigration increased. These two factors led to increased national and regional immigration. This boosted the foreign-born population and its share. The citizenship status chart provides additional insights into the decline in the overall foreign-born population from 2017 to 2021 and the resurgence through 2024. The decline from 2017 to 2021 was largely attributable to the non-citizen populations migrating out of the area in greater amounts than naturalized citizens moving into the area. The resurgence is attributed to the non-citizen population increasing. The naturalized citizen population of the region, on the other hand, remained steady from 2022 to 2024. Loudoun and Prince William Counties, since 2010, have had significant increases in their foreign born population and trended upward in the share of the total population that is foreign born. Fairfax County's foreign born population share has been the largest in the region since 2010. It trended up from 2010 to 2017, reaching a high of 32.1% in 2017. From 2017 to 2021 it trended down, reaching its lowest point in that period at 29.9% in 2021. It then trended up. By 2024 the share had yet to reach the 2017 level. In 2024 it was 30.9%.
