Northern Virginia unemployment claims data and charts for monitoring the federal cutback impacts. Unemployment Claims Reports, maps, and charts are best viewed on a desktop or tablet. Unemployment Claims Unemployment initial and continued claims serve as an indicator of economic health. Initial unemployment claims measure the number of people filing for unemployment benefits for the first time. Continued unemployment claims measure the number of people who already filed an initial claim in a prior week and have subsequently filed a continued claim for unemployment benefits because they continue to be unemployed. The weekly data provides policymakers and economists with the timeliest data about labor market conditions, often foreshadowing broader economic conditions that are reported on a monthly basis in state and federal job reports and databases. About the Data 1. Claims are filed in the jurisdiction where the employee worked. During a filing, each state and the District of Columbia are required to collect place of residence. This collected data is reported and exchanged between the U.S. Department of Labor and the states and the District of Columbia. The following data represents place of residence of the worker filing a claim . It does not represent place of work where the claim was initially filed. 2. Federally filed claims have reporting delays of several weeks or months because a claim is not classified as a federal (UCFE) claim until federal wages are confirmed. Also, individuals who are on administrative leave with pay or voluntarily quit do not qualify for unemployment benefits. Therefore, a large number of federal employees laid off in the first half of 2025 have yet to qualify or be officially confirmed for unemployment claims benefits. ***Friday Updates*** Claims data representing place of residence is submitted by Virginia Employment Commission to the U.S. Department of Labor. This dashboard is updated on Fridays.

The report and a dashboard of key demographic and economic findings from the report are found here. Immigration Study Reports, maps, and charts are best viewed on a desktop or tablet. The Northern Virginia Regional Commission was pleased to collaborate with the Partnership for a New American Economy (NAE) and the Community Foundation for Northern Virginia on the study, One Region: Welcoming New Americans to Northern Virginia. The original study was published on March 12, 2020. It is a study of the economic impact of immigrants to the region. An addendum to the study was published on October 21, 2020 that provides immigrant data relevant to the COVID-19 pandemic crisis response . The research was conducted by NAE. NAE has undertaken similar studies throughout the United States. This One Region report dashboard summarizes and reports on immigration in the Northern Virginia region. This dashboard provides quick access to key data pieces found in the report. This One Region immigration dashboard provides data not only of the overall Northern Virginia region, but also on the localities within the region . A webinar was hosted on October 21, 2020. For copies of the presentations and video recording go to the webinar webpage. Download a copy of the original report, published March 2020 Overview of the One Region Report The One Region report is a comprehensive picture of new Americans in Northern Virginia (NOVA). It highlights the size and rapid growth in the immigrant population in the region and their impact on the local economy, including injecting more money into local businesses, property markets, and municipal budgets as consumers, homebuyers, and taxpayers. Immigrants are major contributors to Northern Virginia's (NOVA) economy as highlighted in the report. The NOVA immigrant population is diverse. These people emigrate, seeking a better life for themselves and their families. “Immigrants are a vital part of the economic and social fabric of Northern Virginia. Their success is our success, and we must continue to be a welcoming community for all to ensure our long-term prosperity,” said P. David Tarter, Chairman of the Northern Virginia Regional Commission and Mayor of the City of Falls Church. Immigrants are an indispensable part of the local Northern Virginia economy at all levels, as workers, business owners, taxpayers and consumers.

Economic data compiled by the Northern Virginia Regional Commission's as part of the One Region immigration study, Coronavirus (COVID-19) immigration study, and dashboard to assess the economic impact of immigrants in Northern Virginia. Economy Key Facts Economy Immigrants hold billions of dollars in economic power and contribute billions to the Northern Virginia economy As Virginia's economy continues to expand, businesses and firms will require more workers across all skill levels to stay competitive and productive. As a tight labor market, with some of the lowest levels of unemployment in the country according to the Bureau of Labor Statistics' 2017 annual averages, much of the labor needed to meet Northern Virginia's demand for workers comes from outside the region, U.S born and immigrant alike.

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 With population growth in the Northern Virginia region has come substantial student enrollment growth in the region's public elementary, middle, and high schools since 2004. On September 30, 2004, there were 315,898 public school students in the region. By September 30, 2019 student enrollment had increased to 423,670. In 2020 the COVID-19 pandemic hit the world. Fall student enrollments have been a different story due to the impacts and transformations caused by the COVID-19. Prior to the pandemic, in 2019 students were 16.7% of the total population. In 2023, the latest year with population available, students were 16.1% of the total population. COVID-19 Pandemic Impact Fall 2020: School enrollment dropped in the region for the first time since at least 2003, with a drop of 16,413. Fall 2021: Enrollment dropped slightly further by fall 2021, with a drop of 626 from 2020. Insights: The enrollment decline during the pandemic was largely attributable to public school students transferring to at-home schooling and private schools, as well as the overall decline in the region's population from mid-2020 to mid-2021. Slow Recovery from COVID-19 Pandemic Fall 2022: Students that were home-school or attended private school during the peak of COVID-19 started to return to public schools and a Northern Virginia population rebound was underway. The 2022 fall enrollment was 4,081 higher than the prior year. Fall 2023/2024: Enrollment in Fall 2024 was 411,097, which lags pre-pandemic enrollment by 12,573 or 3.0% . Fall 2023 enrollment was only 617 students higher than in 2022. Fall 2024 enrollment declined by 232 students from the previous year. Regional Insights: In 2020 and 2021, students were 16.0% of the total population. This increased slightly to 16.1% in 2022 and stayed at that level in 2023, falling short of the pre-pandemic share of 16.7%. The population estimate for 2024 is unavailable until mid-2024. The slow recovery is mirrors the region's slow population rebound . The lower shares observed since 2019 are likely a result of the enhanced appeal of at-home and private schooling following the onset of the COVID-19 pandemic. The slow growth can also be attributed to declining birth rates in Northern Virginia. County/City Insights : The only jurisdictions surpassing the 2019 pre-pandemic enrollment level as of 2024 were the City of Alexandria and the City of Falls Church. Alexandria's enrollment was 16,613 in 2024 compared to 16,307 in 2019. Alexandria's 2024 enrollment was the highest enrollment on record since 1971. Falls Church's enrollment was 2,677 compared to 2,649 in 2019. Alexandria and Falls Church surpassed 2019 pre-pandemic enrollment levels for the first time in 2023 and 2024 respectively. Future Growth and Planning The Washington region is forecasted to have much population growth in the next few decades, according to the Metropolitan Washington Council of Governments (MWCOG). A significant amount of that growth is forecasted to be in Northern Virginia. The Northern Virginia region had a population of over 2.54 million in 2022 and is forecasted to be more than 3 million by 2040. See the NVRC Demographic and Economic Fact Sheet for more details. A multitude of variables alter student enrollment trends, including new development, transfers to and from private schools, in and out migration rates, and changing size and composition of families in existing housing stock. With growth comes challenges in maintaining the high quality of education and school facilities in the region. To maintain the high quality of education, planning and acquiring land or buildings for school sites to accommodate future growth is vitally important, but has been increasingly challenging in this region with quickly diminishing land supply.

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). Median Household Income Overall Reports, maps, and charts are best viewed on a desktop or tablet. Median Household Income of Northern Virginia Overview 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. 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. Median Household Income - Current Five-Year Estimates All jurisdictions in the United States are included in the five-year American Community Survey estimates. The Median household incomes for all Northern Virginia jurisdictions are shown in this graph. The median household income of every Northern Virginia jurisdiction is higher than the Commonwealth of Virginia and the United States. Out of all 3,144 jurisdictions in the USA, three of the five highest ranked for median household income are in Northern Virginia, and those include Loudoun County (1st), Falls Church City (4th), and Fairfax County (5th). Northern Virginia's median household income, at an estimated $142,583 (in 2023 dollars), is higher than 12th ranked Arlington, making Northern Virginia one of the most affluent regions of the USA. Median Household Income - Current One-Year Estimates 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. The median household incomes for the five largest Northern Virginia jurisdictions are shown in this graph. The Northern Virginia median household income for the one-year estimates is representative of the five largest jurisdictions in Northern Virginia only. The five largest jurisdictions of Northern Virginia all have incomes higher 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, three of the top twenty highest income jurisdictions are located in Northern Virginia, and those include Loudoun County (1st), Fairfax County (4th), and Arlington County (19th). The median household income of Northern Virginia's five largest jurisdiction together is estimated to be $149,502 (in 2024 dollars), making Northern Virginia one of the most affluent areas of the USA. Median Household Income - Historic Compared to Current Five-Year Estimates The Northern Virginia region's median household income had been rising since 1999 until it dropped in the 2019-2023 period. The greatest upward transformations in median household income, to levels well beyond inflation, have occurred in the Counties of Arlington and Loudoun. Median Household Income - Historic Compared to Current One-Year Estimates The median household income trend, for the regions large jurisdictions (population of 65,000 or more), are shown in the following graph. The Northern Virginia regional household income distribution for the one-year estimates is representative of the five largest jurisdictions in Northern Virginia only. Key Facts: There were dips in median household income in the early 2010s for some jurisdictions. The effects of the recession from 2007 to 2009 were still causing economic hardships and in 2013 there was federal sequestration when the federal government made large budget cuts. The Northern Virginia region is heavily dependent on the federal government for its economy, as indirectly indicated by the job layoffs during sequestration causing a sharp decline in household incomes. Prior to the COVID-19 pandemic, specifically from 2012 to 2019, the trend in the Northern Virginia median household income was an upward trend after adjusting for inflation. The onset of the COVID-19 pandemic in early 2020 triggered a wave of demographic and economic shifts both regionally and nationally. Between 2019 and 2023 there was a downward trend in the region's median household income after accounting for inflation. Nationally, wage growth outpaced inflation from 2019 through early 2021, lagged behind from early 2021 to mid-2023, and again began to outpace inflation from mid-2023 through 2024. Given that Northern Virginia's downward trend spanned 2019 to 2023, the steady decline is attributable primarily to underlying demographic shifts of this period rather than wages failing to keep pace with inflation. Notably, NVRC research has shown that workers retired early and many middle income office workers moved to more affordable areas as remote work surged. Between 2023 and 2024, median household income in the region increased after adjusting for inflation, similar to the national pattern of wages exceeding inflation. Policymakers have comprehensively addressed low-income housing; however, the pandemic has underscored the need to expand housing programs to serve middle-income two-person households earning up to $150,000 (roughly 120% of the HUD AMI) for enabling first-time home buyers to afford comfortable living and family life in the region. For further information on these demographic shifts, see the NVRC report Shifting Migration Patterns of Northern Virginia: Affordable Housing Needs published January 2025.

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.

Citizenship data compiled by the Northern Virginia Regional Commission's as part of the One Region immigration study, Coronavirus (COVID-19) immigration study, and dashboard to assess the economic impact of immigrants in Northern Virginia. Citizenship Key Facts Citizenship Immigrants in Northern Virginia have above average rates of naturalization 2013 to 2017 Period Key Facts: More than half, or 51.3 percent, of all immigrants in the region, have earned their U.S. citizenship. The Northern Virginia U.S. Citizenship rate of immigrants is higher than the national average of 48 percent. Further information about citizenship, from research NVRC has conducted separately from the One Region report, can be found on the People dashboard .

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 7th in the nation at 36.6%. The town of Herndon has a foreign born population share of 44.0% which is estimated to be higher than the City of Manassas Park, however the town is not statistically different from the city due to the 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 2019-2023 estimate is considered to be highly unreliable due to the large margin of error, its large increase from prior five-year periods, and its rural setting in Loudoun County. 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 28.0% currently. Large transformations since 2000 have occurred in the towns of Dumfries, Haymarket, Leesburg, Lovettsville, Occoquan, Purcellville, and Quantico. 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.
