Census Bureau: U.S. Population Growth Slows Due to Historic Decline in Net International Migration

Population growth in the United States has slowed significantly with an increase of only 1.8 million, or 0.5%, between July 1, 2024, and July 1, 2025, according to the new Vintage 2025 population estimates released today by the U.S. Census Bureau.

This was the nation’s slowest population growth since the early period of the COVID-19 pandemic, when the population grew by a historically low 0.2% in 2021. The slowdown also comes after a sizeable uptick of growth in 2024, when the country added 3.2 million people and grew by 1.0%, the fastest annual population growth rate since 2006.

“The slowdown in U.S. population growth is largely due to a historic decline in net international migration, which dropped from 2.7 million to 1.3 million in the period from July 2024 through June 2025,” said Christine Hartley, assistant division chief for Estimates and Projections at the Census Bureau. “With births and deaths remaining relatively stable compared to the prior year, the sharp decline in net international migration is the main reason for the slower growth rate we see today.”

Slower population growth was felt across the country. All four census regions and every state except Montana and West Virginia saw their growth slow, or their decline accelerate.

Midwest’s Population Growing Again 

The Midwest was the only region where all states gained population from July 2024 to July 2025. In addition, after experiencing population decline in 2021 and small growth in 2022, the Midwest’s population grew solidly in 2023 (259,938), 2024 (386,231), and 2025 (244,385). Slight gains in natural change (births minus deaths) for some of the states in the Midwest contributed to their population growth.

“From July 2024 through June 2025, the Midwest also saw positive net domestic migration for the first time this decade,” said Marc Perry, senior demographer at the Census Bureau. “And while the net domestic migration was a relatively modest 16,000, this is still a notable turnaround from the substantial domestic migration losses in 2021 and 2022 of -175,000 or greater.”

Ohio (net domestic migration of 11,926 in 2025, compared to -32,482 in 2021) and Michigan (net domestic migration of 1,796 in 2025, compared to -28,290 in 2021) exemplify this emerging trend.

South Carolina is the Nation’s Fastest-Growing State

Fueled by a sizeable net domestic migration increase of 66,622, South Carolina’s population grew by 79,958 between July 1, 2024, and July 1, 2025. The increase of 1.5% was the highest of any state and was down somewhat from its 1.8% increase in 2024. Idaho (1.4%) and North Carolina (1.3%) followed closely, with their growth also driven by domestic migration gains. Texas (1.2%) grew rapidly from a combination of natural change and net international migration, despite a sharp slowdown in gains from the latter. Utah (1.0%) grew mainly from natural change, as net international migration — the largest contributor to its growth last year — slowed.

Technical Notes

The most recent net international migration estimates reflect methodological improvements, which include the incorporation of additional administrative data at the subnational level and adjustments to the short-term projection method, which is evident in the national level monthly population totals. Details are available in the Random Samplings blog, “New Population Estimates Show Historic Decline in Net International 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 produces an annual time series of estimates of population. Today’s release includes population totals, components of change, and voting-age population for the nation, 50 states, the District of Columbia, and Puerto Rico.

In March, the Census Bureau is scheduled to release estimates of the July 1, 2025, population totals and components of change for U.S. metropolitan and micropolitan statistical areas and counties and population totals for Puerto Rico municipios. The data will be embargoed. The full release schedule for the Population Estimates Program can be found on the Census Bureau’s website.

With each new release of annual estimates, the entire time series of estimates is revised for all years back to the date of the last census. All previously published estimates (i.e., old vintages) are superseded and archived on the FTP2 site. Due to periodic methodological updates, year-to-year comparisons in the estimates should only be done within the same vintage.
