How the numbers are made
The census counts everyone every 10 years. Between censuses, the Census Bureau’s population estimates program updates each city’s total every July 1 from births, deaths, migration and housing data; the latest is Vintage 2025. The American Community Survey samples households over five years, so its figures describe 2020 to 2024 as a whole and carry margins of error. More figures are in the city’s Census QuickFacts table.
