Key figures (Census Bureau population estimates, Vintage 2025)
As of 14 November 2026, 00:51 KST (retrieved by this page at that time); latest listed on the agency page at retrieval: the Vintage 2025 state population totals file (NST-EST2025-ALLDATA), offered on the Census Bureau's State Population Totals page, which says: "Vintage 2025 is the most recent completed vintage and consistent set of estimates." Estimates refer to July 1 of each year. Primary source: https://www2.census.gov/programs-surveys/popest/datasets/2020-2025/state/totals/NST-EST2025-ALLDATA.csv[1][3]

Comparison basis: all changes are taken within Vintage 2025, as the Census Bureau advises: "Due to periodic methodological updates, year-to-year comparisons in the estimates should only be made within the same vintage." Vintage 2024 values are shown in brackets only to show revision, not for change calculations. Counts are whole persons as printed and are not rounded; the 0.52% is this page's calculation rounded to two decimals. In the file the year's population change equals natural change plus net international migration plus a residual of 0 (this page's check).[1][5]
In three lines
1. The Census Bureau estimates the U.S. resident population at 341,784,857 on July 1, 2025, up 1,781,060 (0.52%) in a year.
2. That gain is about half the 3,248,745 of the year before; in the same file net international migration fell from 2,734,468 to 1,262,202, a drop of about the same size.
3. Natural change stayed near 0.5 million (518,858).[1]
What the estimates are
Annual estimates produced using data on births, deaths and migration. "The Population Estimates Program uses current data on births, deaths and migration to calculate population change since the most recent decennial census (2020 Census) and produce an annual time series of population estimates." The files read here give no error ranges for the estimates.[5]
Each vintage revises the past. "With each new release of annual estimates, the entire time series of estimates is revised for all years back to the last census." So the July 1, 2024 population is 340,110,988 in Vintage 2024 but 340,003,797 in Vintage 2025, 107,191 lower (this page's subtraction).[3][5]
Components. The file gives births, deaths, natural change, international and domestic migration and a residual for each year; for the nation the file shows domestic migration of 0, and the 2025 residual is 0.[1]
Reading in pairs
International migration in two vintages. For the year to July 1, 2024, net international migration is 2,786,119 in Vintage 2024 and 2,734,468 in Vintage 2025, 51,651 lower; the year's total change moved from 3,304,757 to 3,248,745. The Vintage 2025 figure for 2025 (1,262,202) should be compared with 2,734,468, not with the earlier vintage.[1][2]
Where the slowdown shows. Within Vintage 2025, the year's population gain fell by 1,467,685 and net international migration by 1,472,266, while natural change rose by 4,581 (this page's subtraction). The CSV files alone cannot determine the cause.[1]
The Census Bureau's own explanation. In a Random Samplings blog post dated January 27, 2026 (Page Last Revised - March 3, 2026), Population Estimates Program staff wrote: "The large drop in NIM from 2024 to 2026 was caused by both a decrease in immigration and an increase in emigration (people moving out of the United States) during that period." "The 2025 data refer to July 1, 2024, to June 30, 2025." The post also describes changes to how net international migration is estimated for Vintage 2025: "Over the past several years, we have conducted research to make the methodology for estimating NIM more flexible and responsive to short-term fluctuations in migration." Its rounded 1.3 million for 2025 corresponds to the file's 1,262,202. This page quotes that explanation and does not attribute the change to any single policy.[6]
States. By this page's calculation from the July 1 estimates, South Carolina (+1.46%) and Idaho (+1.44%) grew fastest from 2024 to 2025 and Texas added the most people (391,243), while 5 states declined, Vermont the most (-0.29%). These are point estimates without published error ranges in the files read, so close rankings should not be read as firm.[1]
Nation equals the states. The 50 states and the District of Columbia add exactly to the U.S. total of 341,784,857; Puerto Rico is in the file but not in the U.S. total (this page's check).[1]
Dates and next release
Dates kept apart. Estimates: July 1, 2025. State totals page: Page Last Revised - May 26, 2026. Final Vintage 2025 release (characteristics): June 25, 2026, which says: "This is the final release of the Vintage 2025 Population Estimates." It also reports: "The U.S. median age was 39.4 in July 2025, up from 39.2 in July 2024 and 38.6 in April 2020."[3][4][5]
Next release. "The annual population and housing unit estimates are released on a flow basis throughout the year, beginning with the national and state total estimates release in December and ending with the release of population estimates for the nation, states, and counties by demographic characteristics during the following summer." The schedule lists the next national and state totals for December 2026 (7/1/2026 data); the exact day is not given.[4]
