The estimates are based on the 2020 Modified Age and Race Census (MARC) file and include changes from Count Question Resolution, the Post-Census Group Quarters Review, and geographic revisions. The estimates add births to, subtract deaths from, and add net migration to the April 1, 2020 estimates base. For population estimates methodology statements, see https://www.census.gov/programs-surveys/popest/technical-documentation/methodology.html. All geographic boundaries for the 2025 population estimates series are as of January 1, 2025.

1 Total population change includes a residual. This residual represents the change in population that cannot be attributed to any specific demographic component. See Population Estimates Terms and Definitions at https://www.census.gov/programs-surveys/popest/about/glossary.html.
2 Net international migration for the United States includes the international migration of both U.S.-born and non-U.S.-born populations. Specifically, it includes: (a) the net international migration of the non-U.S. born, (b) the net migration of U.S. born to and from the United States, (c) the net migration between the United States and Puerto Rico, and (d) the net movement of the Armed Forces population between the United States and overseas.
