The five-year American Community Survey (ACS) estimates encompass data collected over a span of 60 months. As an illustration, the 2019-2023 ACS 5-year estimates compiled information from January 1, 2019, to December 31, 2023. These five-year estimates are more reliable than one-year estimates and are applicable to small geographical areas, such as the census tract and census block groups that one-year estimates are not available. The five-year estimates are best used when data precision is prioritized over currency and when analyzing very small populations. The links below provide data specific to Fairfax County as a whole.
