Last checked Oct. 19, 2026. Figures come from the U.S. Census Bureau: the 2010 and 2020 census counts, the Vintage 2025 population estimates and the 2020-2024 American Community Survey five-year estimates. Alexandria is an independent city, so the Census Bureau counts it as both a city and a county-level area; the figures are the same.
The Census Bureau estimates that 160,662 people lived in Alexandria on July 1, 2025, the highest figure in the bureau’s counts and estimates since 2010.
