How is this ranking made?

Each place's population change, 2020 to 2025 is read from the Census Bureau's April 1, 2020 estimates base and its July 1, 2025 estimate. A place enters the ranking if it had 1,000 or more residents in the 2020 Census and is incorporated. Ties in the published figure share a rank. This is a measurement of one figure, not a judgment of a place.
