U.S. Population Growth Slowed in 2025: What the Data Shows

The change from July 1, 2024 to July 1, 2025 was 0.52%. In the preceding July-to-July interval, the increase was 0.96%. The numeric increase fell by 1,467,685 residents, or 45.18% relative to that earlier increase. This is a comparison of two annual changes, not a decline in the national population.

The revised series contains 331,578,104 residents in July 2020 and 341,784,857 in July 2025. That five-year gain of 10,206,753 is 3.08%. Calling the whole five-year percentage “annual growth” would overstate the rate. The year-by-year table makes the intervals explicit.

For the annual interval ending June 30, 2025, the source reports 3,620,461 births and 3,101,603 deaths. Their difference is natural change of 518,858. Net international migration contributes 1,262,202. The source residual is 0.

The accounting reconciliation is natural change + net international migration + residual = 1,781,060. Net domestic migration is 0 nationally because a move between two U.S. states does not add or remove a resident from the national universe. Domestic migration matters for individual states and counties, but it should not be counted as another national source of growth.

These figures identify a change in the size of annual growth. They do not, on their own, identify the reason for every move, quantify a particular policy effect or predict next year’s total. The retained normalized collection includes the latest published component interval. It does not contain a matched table of every previous year’s components, so this article does not attribute the entire year-to-year slowdown to a component comparison it has not presented.

A population estimate is a dated statistical observation. It is not a real-time count, and a modeled population clock should not be used as a replacement for the July 1 total. The national resident universe includes the 50 states and DC, excluding Puerto Rico and other territories.

Download the national long CSV and subtract each year’s population from the following year. For a percentage, divide that difference by the starting July 1 population. All six values must come from Vintage 2025; selecting a 2024 number from an older vintage would introduce a revision difference into the growth calculation.

The interactive chart below switches between resident counts and an index with July 2020 equal to 100. An index describes relative change and does not replace the exact integer values in the downloadable data. For component calculations, retain the source residual rather than forcing the births, deaths and migration terms to fit by adjustment.
