Decennial Census Reports, maps, and charts are best viewed on a desktop or tablet. Access and View Data Analyses NVRC Regional Data Analysis Data analyses of 2020 and prior censuses for the Northern Virginia region overall and each of its counties, cities, and towns are posted under the People section of this dashboard. Census Bureau Nationwide Data Analysis The Census Bureau published 2020 Census analyses through a series of data visualizations , America Counts stories , and videos to help illustrate and explain the Census results and the country's demograph ic characteristics. 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. These files contain 2020 Census data on characteristics of the population (i.e. age, sex race), characteristics of households (i.e. household size, rent/own, families).

Detailed Demographic and Housing Characteristics DHC-B The Detailed Demographic and Housing Characteristics Detailed DHC-B released August 2024. The Detailed DHC-B includes detailed household type (e.g., family or non-family) and tenure for approximately 370 racial and ethnic groups and places of origin , such as German, Lebanese, Chinese, and Mexican. Detailed Demographic and Housing Characteristics S-DHC The Detailed Demographic and Housing Characteristics Supplemental DHC (S-DHC) was released September 2024. 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. The following document is a brief overview of DP and the impacts it has on data quality. Click on the image to download. For an in-depth description of DP go to the Census Bureau's DP website .

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

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.

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 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.
