Census's American Community Surveys - Fairfax County Summaries
About the American Community Survey (ACS)
Three-year ACS data sets provide information for areas with populations of 20,000 persons or more. Three-year ACS data are available for some Fairfax County sub-geographies. The three-year ACS data can be obtained directly from the U.S. Census Bureau's American FactFinder tool.
Five-year ACS data sets provide information for areas as small as census block groups.
