If you’re in a trivia league and someone asks, “how many people live in Fairfax County?,” you can answer with confidence: 1,142,888 people.

This number is now available as part of our annual demographics report, which also features population estimates and forecasts; housing units and their characteristics; residential development activity; and commercial and industrial gross floor area. The information is broken down by Board of Supervisors’ districts, towns, planning districts, human services regions, ZIP codes and census tracts.

This report also unlocks the baseline data points as to who we are as a county and community — which then fuels other decisions such as next week’s proposed budget for the next fiscal year and beyond.

There are hundreds of stats to examine in the report, but here are a few noteworthy numbers:


Young, Old and In Between

  • 26.4 percent of residents are children under age 20
  • 11.5 percent of residents are age 65 and older
  • 62.1 percent are the rest of us in between!
