About the Towns Data
All incorporated towns and places in the United States are included in the five-year American Community Survey (ACS) estimates. All of the incorporated towns in Northern Virginia have a population of less than 65,000 persons, and one-year ACS estimates do not exist for incorporated places with a population of less than 65,000. 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 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.
For comparative purposes, Northern Virginia counties and cities, Commonwealth of Virginia, and United States data are provided in the charts.
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, some of it being in incorporated towns. The town of Purcellville has nearly tripled in size since 2000. The town of Lovettsville has more than doubled in size since 2000. The towns of Leesburg and Haymarket have populations that have nearly doubled since 2000. Leesburg's population growth is still sizeable in the 2010's, but the rate of growth has slowed.
A big story of the region is the minority-majority transition. There will soon be a day when the majority of people will belong to a minority group (any group other than non-Hispanic White alone). Much of this is attributed to the sizable increases in the number of Hispanics and Asians in the region. The towns of Dumfries, Herndon, and Quantico are minority-majority.
Foreign Born Population Transformation
Another big story is the foreign born population transforming the region. The Washington, D.C. metropolitan area is one of the most diverse in the country when taking into consideration the minority and foreign born population make-up. Northern Virginia contains a sizable amount of the metropolitan area's diverse population.
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
Foreign Born Population Share - Current
The region's highest ranked county/city is Manassas Park City, ranking 13th in the nation. The town of Herndon has a foreign born population that is significantly higher than Manassas Park City. The towns that are estimated to have less foreign born population shares than the Commonwealth of Virginia are all located within rural Loudoun County (Lovettsville, Purcellville, Hamilton, Middleburg, Round Hill, and Hillsboro), except for Clifton which is located in rural Fairfax County.
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 27.7% (2014-2018 ACS 5Yr Estimate).
A place is considered statistically similar to its characteristics in 2000 if the margin of error causes the low and high range of today's estimate to contain the 2000 figure. If this is the can it can not be said for certain that today's figure is different than in the past, even though the middle of the road estimate or best guess may be higher or lower than in 2000. Today's estimate is considered statistically different if the estimate range does not contain the 2000 figure.
Statistically Similar to 2000: Clifton, Hillsboro, Middleburg, Round Hill
Higher Today and Statistically Different than 2000: Dumfries, Hamilton, Haymarket, Herndon, Leesburg, Lovettsville, Occoquan, Purcellville, Vienna
Lower Today and Statistically Different than 2000: Quantico
Large transformations have occurred in the towns of Dumfries, Haymarket, Leesburg, Lovettsville, Occoquan, and Purcellville. All of these incorporated towns are located in the outer-core, which is where the majority of the region's growth has occured.
