Methodology · sources and limits
Census Vintage 2025 · within-vintage growth only.
Population figures are pop_current from the Census Bureau's Population Estimates Program, Vintage 2025, reference date July 1, 2025. National rank is based on population across all 19,483 cities in the dataset.
All change figures (5-yr Δ columns) are computed within Vintage 2025 only: April 2020 census base to July 2025 estimate. This site does not publish a single 2010→2025 growth figure because Vintage 2019 and Vintage 2025 use different methodologies and reference populations — mixing them would produce misleading numbers.
The filter is inclusive at the upper bound: a city of exactly 9,999 qualifies.
