U.S. Census Bureau — Population Estimates Program — National/State Population Totals, Vintage 2025

Methodology details

The population figure on this page is an annual estimate from the U.S. Census Bureau's Population Estimates Program. Each estimate refers to July 1 of its year, so the most recent figure describes 2025 — not the year you are reading it in.

How the change since 2020 is calculated

Both endpoints come from the same Population Estimates Program release, so the comparison is like for like: 39,527,808 on July 1, 2020 and 39,355,309 on July 1, 2025. The change is the later estimate minus the earlier one (-172,499), and the percentage is that change divided by the 2020 estimate (-0.4%).
