- People Population Overall | Northern Virginia Regional Commission
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 2024, the Northern Virginia population was 77% more than in 1990 when the population was 1,466,350. Population Estimate 2024 2,601,818 The COVID-19 pandemic began in the United States in March 2020 and the emergency declaration was lifted in May 2023. The pandemic changed the country's and region's demographic migration patterns significantly due to the substantial rise in remote work. Remote work is providing people with the opportunity to move to places away from employment centers. Most people relocate for family-reasons, housing reasons, and for more affordable, lower cost of living according to the U.S. Census Bureau Current Population Survey. Young adult, first time home buyers are the largest, working-age demographic group that are choosing to move to more affordable areas. In the four years since the pandemic, the country has had a wave of out-migration from urban areas to suburban and rural areas or smaller urban areas. The shift to remote work is one of the most impactful societal changes impacting demographic trends in the country and region, and likely will shape future trends for a long time. From July 1, 2020 to July 1, 2021, the nation's most populous areas, including Northern Virginia, experienced significant out migration and population declines. This was the first and only annual decline in Northern Virginia since the Census Bureau annual record keeping began in 1970, with a decline of an estimated 7,800 persons. 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.

Language Spoken Key Facts Language Spoken Understanding the population with language barriers is particularly critical for the quick and accurate dissemination of health, safety, and public information. 2014 to 2018 Five-Year Estimates Key Facts: There are an estimated 584,000 people in Northern Virginia who live in a household where English is not spoken at home as the primary language. Of those, 31.2 percent of the population age five and over speak Spanish at home. Of those, the second most spoken language is Korean at 5.5 percent. There are an estimated 134,200 people in Northern Virginia who report speaking English less than well, making up 5.4 percent of the region's total population.

- Education Attainment of Towns | Northern Virginia Regional Commission
Northern Virginia towns 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 of Towns Reports, maps, and charts are best viewed on a desktop or tablet. Educational Attainment of Towns 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 60.4%, which is nearly double the United States, and holding a graduate or professional degree is 29.4%, 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. All of the incorporated towns in Northern Virginia have a population of less than 65,000 persons. One-year ACS estimates do not exist for incorporated places with a population of less than 65,000. All incorporated towns and places in the United States are included in the five-year ACS estimates. It is important to note that any data sourced from the ACS is based on a small sample of the population of a place. The ACS estimates for places with smaller populations such as Clifton, Dumfries, Hamilton, Haymarket, Hillsboro, Lovettsville, Middleburg, and Quantico can be unreliable if the margin of error is large. 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. Educational Attainment - Current Bachelor's or Higher Degrees - Current The population age 25 or over with bachelor's or higher degrees of the counties, cities, and incorporated towns in Northern Virginia is shown in this graph. All towns, except for Dumfries, have higher percentages of bachelor's or higher degree holders than the United States and Commonwealth of Virginia. The towns of Clifton and Vienna have higher percentages of bachelor's or higher degree holders than Northern Virginia overall. Graduate or Professional Degrees - Current The population age 25 or over with graduate or professional degrees of the counties, cities, and incorporated towns in Northern Virginia is shown in this graph. The towns of Clifton and Vienna have higher percentages of bachelor's or higher degree holders than Northern Virginia overall. Educational Attainment - Historic Compared to Current Bachelor's or Higher Degrees - Historic Compared to Current The trend over time in the population age 25 or over with bachelor's or higher degrees in Northern Virginia and its incorporated towns are shown in this graph. Due to the small size of many towns, the educational attainment data of towns should be used with caution and the margin of error of the educational attainment data 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. Graduate or Professional Degree - Historic Compared to Current The trend over time in the population age 25 or over with graduate or professional degrees in Northern Virginia and its incorporated towns are shown in this graph. Due to the small size of many towns, the educational attainment data of towns should be used with caution and the margin of error of the educational attainment data 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.

Northern Virginia income, economically disadvantage populations, workforce, and more demographics, data and graphs by region and county. Analyzed by the Northern Virginia Regional Commission (NVRC). Household Income Distribution Overall Reports, maps, and charts are best viewed on a desktop or tablet. Household Income Distribution of Northern Virginia Northern Virginia is known for having communities with some of the highest incomes in the United States, including the county with the highest median household income in the nation. High incomes coincide with the large, thriving business community of the Northern Virginia region. While high incomes exist, we must recognize that there are segments of the community that are lower income and in need of assistance that live in this prosperous region of the country. About the Data and Proper Data Interpretation Median household income 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. Five-Year Estimates - Current All jurisdictions in the United States are included in the five-year American Community Survey estimates. The share of households in each income cohort for all jurisdictions in Northern Virginia are shown in this graph. While Northern Virginia is known for having communities with some of the highest median incomes in the United States, it must be recognized that there are segments of the community in need of assistance that live in one of the most prosperous regions in the country. It also must be recognized that the region's high cost of housing can be burdensome for both the low and moderate income households (earning up to $150,000), particularly first time home buyers , so there is a significant need for more affordable housing. For further information on the affordable housing needs for the middle-income, see the NVRC report Shifting Migration Patterns of Northern Virginia: Affordable Housing Needs published January 2025. One-Year Estimates - Current Those jurisdictions with a population of 65,000 or more are included in the one-year American Community Survey estimates, of which there are five Northern Virginia jurisdictions included. The share of households in each income cohort for the five largest jurisdictions in Northern Virginia are shown in this graph. The Northern Virginia regional household income distribution, for the one-year estimates, is representative of the five largest jurisdictions in Northern Virginia only. While Northern Virginia is known for having communities with some of the highest median incomes in the United States, it must be recognized that there are segments of the community in need of assistance that live in one of the most prosperous regions in the country. It also must be recognized that the region's high cost of housing can be burdensome for both the low and moderate income households (earning up to $150,000), particularly first time home buyers, so there is a significant need for more affordable housing.

Northern Virginia town income, economically disadvantage populations, and more demographics, data and graphs. Analyzed by the Northern Virginia Regional Commission (NVRC). Economics of Towns Economics of Towns Data There are 14 incorporated towns in Northern Virginia. For comparative purposes, Northern Virginia counties and cities, Commonwealth of Virginia, and United States data are provided in the graphs. About the Data and Proper Data Interpretation The economic data of incorporated towns is sourced from the 2000 Census and the American Community Survey (ACS). All of the incorporated towns in N orthern Virginia have a population of less than 65,000 persons. One-year ACS estimates do not exist for incorporated places with a population of less than 65,000. All incorporated towns and places in the United States are included in the five-year ACS estimates. It is important to note that any data sourced from the ACS is based on a small sample of the population of a place. The ACS estimates for places with smaller populations such as Clifton, Dumfries, Hamilton, Haymarket, Hillsboro, Lovettsville, Middleburg, and Quantico can be unreliable if the margin of error is large. A town's margin of area for an ACS data piece can be found by hovering over the town's data in a graph. 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. Only data variables that are deemed relatively reliable have data provided at the town level. For instance, poverty data is unreliable for many towns in Northern Virginia so that data is not being provided. Median Household Income

- People Race of Towns | Northern Virginia Regional Commission
Northern Virginia town population growth, minority-majority transition, foreign born population transformation, and more demographics, data and graphs. Analyzed by the Northern Virginia Regional Commission (NVRC). Race and Ethnicity of Towns Reports, maps, and charts are best viewed on a desktop or tablet. Race and Ethnicity of Towns Overview A big story of the region is its diversification and majority-minority transition. There will soon be a day when the majority of people will belong to a minority group (any group other than non-Hispanic White alone). Much of this is attributed to the sizable increases in the number of Hispanics, Asians, and multiracial persons in the region. The following charts show the region's population by race and ethnicity, along with analyses of diversity for Northern Virginia and its incorporated towns. Upcoming Changes to Categorization of Race/Ethnicity Race/ethnicity data collected by the U.S. Census Bureau is the primary source of race and ethnicity demographics. The U.S. Census Bureau currently collects race and ethnicity data based on the U.S. Office of Management and Budget (OMB) standards from 1997. New race/ethnicity standards were adopted by the Office of Management and Budget on March 28, 2024, the first such adoption since 1997. Changes are coming to how race and ethnicity information will be collected and reported in the United States. Federal agencies, including the U.S. Census Bureau, must implement the new standards into data collections as soon as possible, but no later than March 28, 2029. The U.S. Census Bureau American Community Survey (ACS), a survey conducted annually, will be one of the first U.S. Census Bureau products to implement the new standards. As of July 2024, the U.S. Census Bureau was proposing to begin implementation of data collection in 2026 or 2027 for the ACS products. The 2030 Decennial Census will also reflect the new standards. The new race categories will offer individuals more precise ways to self-identify, especially for people who self-identify as multiracial or multiethnic. This will result in a more accurate representation of the U.S. population's race and ethnic characteristics. Changes will include a single combined question instead of separate race and ethnicity questions. Also, a new "Middle Eastern or North African" category will be added. These changes aim to better reflect the diversity of the American population. These changes will create challenges and implications for our understanding of the population and trends because the data will not be comparable to prior data. These modifications will alter the population size of subgroups. Specifically, the Census Bureau’s 2015 National Content Test results suggest anticipating increases in those identifying as Middle Eastern or North African, Hispanic or Latino, and Black or African American. Conversely, the number of individuals categorized as “white” or "some other race" is projected to decline. The combined race and ethnicity question is also expected to improve response rates for the race component on the decennial census and ACS forms. More information can be found on the U.S. Census Bureau's website . Decennial Census Data 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. The 2020 Census had improvements to the design of the two separate questions for race and ethnicity, data processing, and coding, which enabled a more thorough and accurate depiction of how people prefer to self-identify. These changes along with actual demographic changes in the population result in the changes seen from 2010 to 2020 in the following data. For more details on the 2020 Census questionnaire changes and its impacts please view the U.S. Census Bureau's technical information . The following charts show the region's population by race and ethnicity, along with analyses of diversity for Northern Virginia and its incorporated towns. People of Hispanic/Latino origin are an ethnic group and may be of any race. To display Hispanic/Latino together with racial groups, it is common to cross-tabulate race and ethnicity to display Hispanic/Latino as a single category and the non-Hispanic race groups as categories that sum to the total population. This means of displaying race and ethnic data has become quite common and for available data, it is the closest categorization c ompared to the new race/ethnicity standards that were adopted by the Office of Management and Budget on March 28, 2024 (for more information see prior section ). With this classification, Hispanic/Latino is treated identically to major race groups and not independently of race. Also, Census Bureau research has shown that this classification is much less impacted by the 2020 Census questionnaire improvements. NVRC has migrated its demographic analysis to the cross-tabulated categories. The following charts, as well as the calculation of diversity, use the cross-tabulated categories.
