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).

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 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 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 educational attainment, public school student enrollment, and more demographics, data and graphs by region and county. Analyzed by the Northern Virginia Regional Commission (NVRC). Student Enrollment Overall Reports, maps, and charts are best viewed on a desktop or tablet. Public School Student Enrollment of Northern Virginia Overview Northern Virginia experienced sustained public school enrollment growth from 2004 through 2019, increasing from 315,898 students to a peak of 423,670. Since 2019, enrollment has declined in four of the past six years, including the most recent school year. Student enrollment in 2025 totaled 405,457. Note, the annual enrollment figures reflect September 30th of each year. Key Highlights Declining Student to Total Population Share: Since 2019, both total enrollment and the student share of the population have fallen. The student share declined from 16.7% in 2019 to a low of 15.8% in 2024. The 2025 share is currently unavailable, but will be available in mid-2026 when population data for 2025 is released by the U.S. Census Bureau. Multiple Contributing Factors: Recent declines in public school enrollment reflect a combination of factors, including declining births and birth rates, an aging population, accelerated out-migration of families due to housing costs, and elevation participation in home-schooling and private education options post-COVID 19 pandemic. Generational Transition: Public school enrollment trends closely track regional birth patterns, typically with a five-year lag. Births and birth rates in Northern Virginia have declined steadily since 2007, resulting in progressively smaller elementary school enrollment since 2013. Larger pre-2013 cohorts that supported enrollment growth are graduating and being replaced by smaller student populations, making continued enrollment decline increasingly likely. Future Growth and Planning Northern Virginia is undergoing a generational transition in its student population. The larger student populations that entered school prior to 2013 and sustained growth through the 2010s are now graduating from the school system, while smaller student populations advance through each grade. Continued enrollment declines are increasingly likely over the next five to ten years. In the longer term, Northern Virginia is projected to have substantial population growth. The region's population exceeded 2.60 million in 2024 and is forecast to surpass 3 million by 2040, according to the NVRC Demographic and Economic Fact Sheet . However, aging of the population and declining birth rates are reducing the number of school-age children entering the public school system. In addition, higher housing costs and other economic pressures are contributing to slow in-migration of families and prompting families to move out of the region. These factors are expected to result in overall stagnation or declines in student enrollment for the region, but specific areas of the region with large amounts of residential development will have increased enrollment. In summary, a multitude of variables alter student enrollment trends, including new development, transfers to and from private schools, in- and out-migration rates, and size and composition of families in existing housing stock. With growth and demographic shifts comes challenges in maintaining the high quality of education and school facilities in the region. Ensuring the continued excellence of education necessitates strategic planning and the acquisition of land or facilities for future school development, which has become increasingly complex in the region due to the limited supply of available land.

Immigrant labor force 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. Labor Force: COVID-19 Pandemic Reports, maps, and charts are best viewed on a desktop or tablet. Key Facts Labor Force - COVID-19 Immigrants are heavily represented among the region's frontline essential and healthcare workforce fighting against the virus and keeping the region running. Workers in essential industries are typically unable to work remotely, increasing their risk of exposure to the disease. Workers in non-essential industries have been severely affected by the economic fallout of the coronavirus outbreak, especially those who cannot work remotely or whose places of work depend normally on face-to-face interaction. 2014 to 2018 Period Key Facts: More than an estimated 410,000 workers in Northern Virginia work in essential industries and occupations. 47.9 percent of all essential workers in Northern Virginia are foreign born. The total population of Northern Virginia is 27.6% foreign born. This indicates that immigrants are disproportionately affected. More than 40 percent of all essential healthcare workers in Northern Virginia are foreign born. Within essential healthcare occupations, foreign born makes up more than half of all nursing assistants, personal care aides, lab technologists and technicians, and licensed practical or vocational nurses. 38.7 percent of all non-essential industry workers in Northern Virginia are foreign born. STEM work is vital to Northern Virginia's economy. Foreign born workers comprise more than half of financial services and more than one quarter of transportation, retail trade, educational services, and healthcare and social services.

Housing characteristics 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. Housing Characteristics Reports, maps, and charts are best viewed on a desktop or tablet. Key Facts Housing Foreign born headed households, especially those on the lower end of the income spectrum have significantly larger household sizes than U.S. born headed households. COVID-19 More occupants per household present opportunities for transmission of COVID-19 among members within that household since COVID-19 is spread through close contact. Housing instability from the pandemic requires a very proactive role from local communities. 2014 to 2018 Five-Year Estimates Key Facts: Foreign born headed households, in general, are larger than U.S. Born headed households in Northern Virginia and its localities. Northern Virginia has a foreign born average household size of 3.22, while U.S. born headed is 2.39. The gap between the foreign born and U.S. born average household size in Northern Virginia shrinks with each higher income quintile, almost reaching parity at the top among the highest income households. The lowest income quintile has a gap of 0.9 persons per household, while the highest income quintile has a gap of 0.2 persons per household. The housing tenure of the foreign born in Northern Virginia is 58 percent owner and 42 percent renter. This distribution varies widely by locality. The innermost, urban localities of Arlington and Alexandria have a higher rate of renters than the outer, suburban localities. The housing type of the foreign born in Northern Virginia is 60.5 percent single-family, 37.5 percent multi-family, and 2.0 percent other. This distribution varies widely by locality. The innermost, urban localities of Alexandria and Arlington have a majority residing in multi-family and the outer, suburban localities have a majority residing in single-family.
