State of the Region: Economic Recovery and Transformation from COVID-19 Pandemic Information on the state of the Northern Virginia region's economic recovery and the transformation from the coronavirus COVID-19 pandemic is found in the State of the Region July 2022 report. As society eases back to normalcy, people have been returning to the labor force, but – despite many people returning to the labor force and new entrants to the Northern Virginia labor force – there are currently not enough workers to meet the labor force demands across various industries in the region. The region’s labor force is significantly down from February 2020, there are a high number of job postings, and there is a low unemployment rate. The economic effect of the COVID-19 pandemic and the economic recovery has been uneven across industries and demographic groups in Northern Virginia. Understanding why the Northern Virginia region’s labor force has declined, why those people in Northern Virginia who left the labor force during the pandemic are not returning in full, and how to overcome a shortage of labor is critical to fostering an economy and community where residents and businesses can thrive. This report provides detailed information on these factors. Click on image for report Economic Recovery COVID19 Minority-Owned Businesses Minority-Owned Businesses of Northern Virginia Minority-owned businesses have experienced heightened risk associated with the COVID-19 pandemic. The COVID-19 pandemic has had a complex effect on the region’s local economy and on the wellbeing of its minority-owned businesses. Northern Virginia is home to 128,000 minority-owned businesses, representing the community’s diverse fabric and entrepreneurship. The report on Supporting Northern Virginia's Minority-Owned Businesses was released on June 23, 2021. The report contains detailed information on the minority-owned business community, how they were impacted by the pandemic, and recommendations for supporting them through the pandemic economic recovery and in the future beyond the pandemic.

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 town population growth, minority-majority transition, foreign born population transformation, and more demographics, data and graphs. Analyzed by the Northern Virginia Regional Commission (NVRC). Foreign Born and Immigrants of Towns Reports, maps, and charts are best viewed on a desktop or tablet. Foreign Born and Immigrant Population of Towns Overview The Washington, D.C. metropolitan area is one of the most diverse in the country when taking into consideration the minority 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 and many of it's towns. Note, the terms foreign born and immigrant are used interchangeably throughout the NOVA Region Dashboard. It is immigration that has been driving many of the major demographic trends in the region, including: School enrollment changes Sizable increases in the number of Hispanics and Asians Population and labor force 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. 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. Foreign Born Population - Current Foreign Born Population Share - Current The region's highest ranked county/city is Manassas Park City, ranking 8th in the nation at 36.8%. Herndon boasts one of the largest foreign-born populations in the country, at 42.2%. Statistically, Herndon is not significantly different from Manassas Park due to the data's margins of error. Towns that are estimated to have lower foreign born population shares than the Commonwealth of Virginia are all located within rural Loudoun County (Lovettsville, Purcellville, Hamilton, Middleburg, Round Hill), except for Clifton which is located in rural Fairfax County. Note, the town of Hillsboro's 2020-2024 estimate of 29.1% foreign born is considered highly unreliable. This is evidenced by the large rise compared to previous five-year periods, as shown in the Historic Compared to Current chart in the next section. It is additionally reinforced by the wide margin of error of +/-37.6%, which stems from the town's small survey sample size. Foreign Born Population - Historic Compared to Current Foreign Born Population Share - Historic Compared to Current Immigration has been driving many of the major demographic trends in the region. The foreign born population is transforming the region. Northern Virginia's population was 21.4% foreign born in 2000 and has risen to 28.2% currently. The largest transformations since 2000 have occurred in the towns of Dumfries, Haymarket, Leesburg, Lovettsville, and Occoquan. All of these incorporated towns are located in the outer-core, which is where the majority of the region's growth has occurred. Note, the American Community Survey is a survey with a small sample size. Due to the small size of many Northern Virginia towns and small sample size of the survey, the median household income of towns 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 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 Population of Northern Virginia Data 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. The April 1st Decennial Census population of Northern Virginia was 1,466,350 in 1990, 1,815,197 in 2000, 2,230,623 in 2010, and 2,550,377 in 2020. On July 1, 2025 the Northern Virginia population was estimated to be 2,628,004. Detailed information on the region and its counties and cities are available on the following population topics .

Immigrant healthcare coverage data compiled by the Northern Virginia Regional Commission's as part of the One Region immigration study, Coronavirus (COVID-19) immigration study, and data dashboard to assess the economic impact of immigrants in Northern Virginia. Healthcare Reports, maps, and charts are best viewed on a desktop or tablet. Key Facts Healthcare Access to healthcare and medical services is critical for well-being A healthy population and a healthy workforce are essential to a thriving community regardless of immigration status. To overcome this pandemic, it is vital that communities look at creative ways to ensure that everyone stays safe and healthy. 2014 to 2018 Five-Year Estimates Key Facts: The foreign born make up a significant share of those lacking health insurance. Approximately 1 out of 5 foreign born persons are uninsured in Northern Virginia, which is significantly higher than the U.S. born population uninsured rate. Approximately 1 out of 20 U.S. born are uninsured. Foreign born make up almost 65 percent of all uninsured in Northern Virginia, while the overall foreign born population is 27.6 percent. The foreign born are clearly disproportionately burdened. Central American countries and Mexico, which are generally Hispanic, make up the largest share of the foreign born population without insurance in Northern Virginia.

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). Education of Towns Education Data of Towns 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 education data of incorporated towns is sourced from the U.S. Census Bureau 2000 Census and the American Community Survey (ACS). 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. 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 shown. Educational Attainment

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). Race and Ethnicity Overall Reports, maps, and charts are best viewed on a desktop or tablet. Race and Ethnicity of Northern Virginia Overview A big story of the region is its racial and ethnic diversity and continuing diversification. Northern Virginia's racial and ethnic composition makes it more diverse today than the United State and Virginia and this has been the case for decades. Much of the continued diversification 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 counties and cities. 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.

Northern Virginia town economically disadvantaged populations, poverty, free and reduced price school meal (FARM) student and more demographics, data and graphs. Analyzed by the Northern Virginia Regional Commission (NVRC). Economically Disadvantaged Overall Reports, maps, and charts are best viewed on a desktop or tablet. Economically Disadvantaged of Northern Virginia While Northern Virginia is known for having communities with some of the highest median incomes in the United States, we must recognize that there are segments of the community in need of assistance that live in one of the most prosperous regions in the country. Poverty The Northern Virginia region has some of the highest household incomes in the United States. However, there are persons in poverty in the region, and their needs must be recognized and addressed. The poverty rates of all counties and cities in Northern Virginia are shown in the following graphs. The poverty rate is the ratio of the number of persons in poverty divided by the number of persons for whom poverty status was determined. Not everyone had their poverty status determined so this figure will be less than the total population. About the Data and Proper Data Interpretation Poverty 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 Poverty Rate - Current Five-Year Estimates Northern Virginia's poverty rate is 6.0%, compared to 9.9% for Virginia and 12.5% for the nation according to the U.S. Census Bureau American Community Survey. All jurisdictions in the United States are included in the five-year American Community Survey estimates. Out of all 3,144 jurisdictions in the USA, two of the fifteen lowest poverty rates are located in the Northern Virginia localities of Falls Church (8th) and Loudoun County (12th). Loudoun County and Falls Church are also the 1stt and 11th ranked for median household income, respectively. However, there are persons in poverty in Loudoun, Falls Church, and the rest of the region, and their needs must be recognized and addressed. Poverty Rate - 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 poverty rates for the five largest jurisdictions in Northern Virginia are shown in this graph. The Northern Virginia regional poverty rate was 6.1% in 2024, which is nearly half the poverty rate of the nation. Out of the 850 jurisdictions with a population of 65,000 or more in the USA, one of the twenty lowest poverty rates is located in the Northern Virginia locality of Loudoun County (20th). Loudoun County is also the number one ranked for median household income. However, there are persons in poverty in Loudoun and the rest of the region and their needs must be recognized. Poverty Rate - Historic Compared to Current Five-Year Estimates Northern Virginia's poverty rate has experienced a similar pattern to the Commonwealth of Virginia and the United States over time. From 1999 to the 2010-2014 period there was an increase in the percent of persons in poverty. The rate in poverty has gradually lessened since the 2010-2014 period, reaching 6.0% in the 2020-2024 period. Poverty Rate - Historic Compared to Current One-Year Estimates The poverty rate patterns over time, for the regions large jurisdictions (population of 65,000 or more), are shown in the following graph. The Northern Virginia regional poverty rate, for the one-year estimates, represents the five largest jurisdictions in Northern Virginia only. The persons in poverty data has large year-to-year fluctuations due to the small sample size of the survey, together with the small amount of persons in poverty. The margins of error (displayed in the graph pop-ups), are large for the poverty one-years estimates, making any poverty trends undiscernible. However, the low to high ranges of poverty over time for each jurisdiction and the region, and comparisons between jurisdictions and the region can be gleaned. For instance, Northern Virginia's poverty rate has ranged from approximately 6% to 7% between 2010 and 2024, and Loudoun County’s poverty rate has been consistently lower than the other large jurisdictions. Given the unreliability of single-year poverty estimates, utilization of five-year estimates are strongly recommended for all Northern Virginia jurisdictions and the region when analyzing trends, planning, and developing policies. The American Community Survey 5-year estimates have a significantly larger sample size.

Access and View U.S. Census Bureau Products Decennial Censuses are released in multiple phases through multiple products. Starting with the 2020 Decennial Census, t he Demographic Profile, Demographic and Housing Characteristics, and redistricting data products all are injected with random statistical “noise” using the differential privacy approach to prevent disclosure of personal information. Caution should be utilized when using this data. The larger the population size of a geographic area, the more accurate the data and the diminished likelihood of having implausible data. Statistical noise is infused to protect confidentiality. The impact of statistical noise decreases with larger geographies. For more information, on the statistic noise injected, privacy, and accuracy, see the information under Privacy and Accuracy of 2020 Census Data . Demographic Profile and Demographic and Housing Characteristics The 2020 Census Demographic Profile and Demographic and Housing Characteristics were released in May 2023.

It includes complex relationships between the characteristics about households and the people living in them, including average household size, average household size by age and tenure, and household and family type for people under 18 years old. Privacy and Accuracy of 2020 Census Data The Demographic Profile, Demographic and Housing Characteristics, and redistricting data all are injected with random statistical “noise” using the differential privacy approach to prevent disclosure of personal information. For the Demographic and Housing Characteristics, the Census Bureau released statistical error metrics (Excel File) to help users understand the variation in the data introduced by using differential privacy. Additional guidance to users is provided by the U.S. Census Bureau in the blog post, What to Expect: Disclosure Avoidance and the 2020 Census Demographic and Housing Characteristics File . For decades, the U.S. Census Bureau has used different techniques to protect individual privacy through their Disclosure Avoidance System (DAS). Differential Privacy (DP) is the latest technique. This technique was chosen because enhanced privacy protection is needed due to advances in technology that enable the ability to identify individuals when combined with other information. DP impacts data accuracy more than any other technique previously applied to decennial census results. DP will add random data (“noise”) to counts for geographic areas below the state level, to prevent identification of individuals. The amount of noise added to the data will be greater than any prior decennial census technique. The impact of statistical noise decreases the larger the population size of a geographic area. From 2019 through 2022, Northern Virginia jurisdictions, through the Northern Virginia Regional Commission (NVRC), participated in the U.S. Census Bureau’s DP demonstration data review and provided feedback to the U.S. Census Bureau.

Internet access information compiled by the Northern Virginia Regional Commission's as part of the One Region immigration study, coronavirus (COVID-19) immigration study, and data dashboard to assess the economic impact of immigrants in Northern Virginia. Internet Access Reports, maps, and charts are best viewed on a desktop or tablet. Key Facts Internet Access Limited or no internet access at home can lead to severe economic fallout, from limiting one's ability to work remotely to hindering a small business's transition to online. Limited or no internet access at home puts children in foreign-born households at risk of falling behind as schools hold classes online due to COVID-19. 2014 to 2018 Five-Year Estimates In total, 10.1 percent of Northern Virginians report lacking wired internet access at home. Either they are without any internet access (including no mobile) or they only have mobile access. Immigrants are disproportionately affected. Without Internet Access at Home 4.0 percent of Northern Virginians report lacking access to the internet at home. 6.1 percent of foreign born in Northern Virginia report lacking access to the internet at home, compared to 3.1 percent of U.S. born. Of those without internet access at home, 42.7 percent were foreign born. The total population of Northern Virginia is 27.6 percent foreign born. This indicates that immigrants are disproportionately affected. Only Mobile Access At Home 6.1 percent of Northern Virginians report having only mobile access to the internet at home. 7.7 percent of foreign born in Northern Virginia report lacking access to the internet at home, compared to 5.4 percent of U.S. born.
