Denver population history

The six July 1 estimates in the table belong to one consistent Vintage 2025 series. The Census Bureau revises earlier years when it releases a new vintage; a figure from an older publication may differ from the value below.

Why is the April 2020 estimates base different from a census count?

The PEP estimates base here is 715,509 residents on April 1, 2020. It incorporates the Census Bureau’s corrections and geographic revisions and serves as the starting point for this annual series. It is not labeled an original 2020 census count. The chart starts at July 1, 2020, so its five-year change uses two July observations. Read about measurement types.

The April 2020 census count (715,522) and the Vintage 2025 April 2020 base (715,509) differ by 13. The gap comes from boundary changes and the Census Bureau’s revised 2020 base, not population change, so measure growth within one series. Source and download

Growth and density

Between July 1, 2020 and July 1, 2025, Denver gained 22,933 residents, a 3.20% increase. The annualized change over these five elapsed years was +0.63%. Annualized change is a summary of the interval; it does not imply that the population changed at that rate in every year.

The 2025 Gazetteer reports 153.07 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 4,838.3 people per square mile. Water area is excluded. Density depends on geographic boundaries. It describes this entire place, rather than a typical neighborhood or built-up area.

Calculations use unrounded source values. Population counts are displayed as integers, percentages to two decimals and density to one decimal. Calculation methods · Growth calculator

How Denver compares

Growth rates below use the same Vintage 2025 series for every row, so they can be compared directly. A city’s rate can differ sharply from its county’s because the county also includes other towns and unincorporated areas.

Geographic context

This figure covers the residents inside Denver’s municipal boundary on July 1, 2025. It is not a metropolitan-area total, and figures for a ZIP code, school district or mailing address area cover different territory, so they usually differ. Denver lies in Denver County, according to the published county/place-part relationships.
