Census says U.S. population growth slowed sharply as net international migration fell
The U.S. population grew by 1.8 million people, or 0.5%, between July 1, 2024, and July 1, 2025, according to new Census Bureau estimates. The increase was the slowest since the early COVID-19 period, when the population grew 0.2% in 2021.
The main driver was a historic decline in net international migration. The Census Bureau said net international migration fell from 2.7 million in the comparable previous period to 1.3 million, a decrease of 53.8%.
The figures provide a new national snapshot of population change and carry implications for the country’s labor supply, school enrollment, housing demand, regional growth and age structure. They are estimates, however, and may be revised in later Census releases.
Migration decline drove the slowdown
Net international migration measures the difference between people entering and leaving the United States from abroad. In the latest estimate period, that measure contributed substantially less to population growth than it did during the prior comparable period.
Natural increase — the number of births minus the number of deaths — was about 519,000 between July 1, 2024, and June 30, 2025. The Census Bureau identified reduced net international migration as the principal reason overall population growth slowed.
That distinction matters: the new figures do not show that births or deaths alone caused the national slowdown. Instead, the estimates point to a sharp change in migration as the central factor in the year-to-year comparison.
The bureau projected that net international migration could fall to approximately 321,000 by July 2026 if current trends continued. That number is a projection, not a finalized count, and should not be treated as the result of the next estimate period.
Every region grew, but rates weakened
All four U.S. regions recorded population growth during the period covered by the Vintage 2025 estimates. The pace was not uniform, and the regional figures showed particular slowdowns in the South and Northeast.
Population growth in the South fell below 1% for the first time since 2021, reaching 0.9%. The region has been an important part of the national growth picture, but the new estimate shows that its expansion also decelerated.
In the Northeast, the growth rate fell to 0.2%, compared with 0.8% the previous year. The Census figures describe regional differences rather than a single, uniform demographic effect across every state.
The release does not establish that all states experienced the same change or that every community will face identical consequences. Local population patterns can differ even when the national and regional totals move in the same direction.
What to watch next
For policymakers, businesses and communities, the estimates offer an updated baseline for considering future demand for workers, classrooms, homes and services. The effect of slower growth will depend in part on how migration, natural increase and regional patterns develop in subsequent periods.
The Census Bureau’s population-estimate schedule identifies the timing for national and state releases, including the next Vintage 2026 schedule. Future releases will provide additional estimates and may revise the figures reported in the Vintage 2025 release.
For now, the clearest finding is that the United States continued to grow in the year ending July 1, 2025, but at a markedly slower pace — chiefly because net international migration dropped by more than half from the previous comparable period.
