Population is the most frequently requested demographic statistic.

What are demographic statistics?

Demographic statistics summarize characteristics of the population in a given place. For individuals, these data represent residents’ characteristics such as age, sex, race, and ethnicity. At the household-level, demographic data include household composition and homeownership characteristics. Demographic data also contain information on student populations and economic activity. Local decision-makers use information on these topics to better serve their residents equitably

Demographic data are difficult to interpret without a point of comparison. Throughout this website, we provide four points of comparison for every metric:

  1. The United States
  2. Washington, DC, one of our neighbors to the north
  3. Arlington County, another neighbor to the north
  4. Fairfax County, our neighbor to the south and west

The map to the right shows how the sub-national geographies relate to one another.
