The 0.5% growth rate for 2025 was a sharp drop from 2024’s almost 1% growth rate, which was the highest in two decades and was fueled by immigration. The 2024 estimates put the U.S. population at 340 million people.
Births outnumbered deaths last year by 519,000 people.
The immigration drop dented growth in several states that traditionally have been immigrant magnets.
California had a net population loss of 9,500 people in 2025, a stark change from the previous year, when it gained 232,000 residents, even though roughly the same number of Californians already living in the state moved out in both years. The difference was immigration since the number of net immigrants who moved into the state dropped from 361,000 people in 2024 to 109,000 in 2025.
Florida had year-to-year drops in both immigrants and people moving in from other states. The Sunshine State, which has become more expensive in recent years from surging property values and higher home insurance costs, had only 22,000 domestic migrants in 2025, compared with 64,000 people in 2024, and the net number of immigrants dropped from more than 411,000 people to 178,000 people.
New York added only 1,008 people in 2025, mostly because the state’s net migration from immigrants dropped from 207,000 people to 95,600 people.
South Carolina, Idaho and North Carolina had the highest year-over-year growth rates, ranging from 1.3% to 1.5%. Texas, Florida and North Carolina added the most people in pure numbers.
The numbers made public Tuesday reflect change from July 2024 to July 2025, covering the end of President Joe Biden’s Democratic administration and the first half of Trump’s first year back in office.
“They do reflect recent trends we have seen in out-migration, where the numbers of people coming in is down and the numbers going out is up,” Eric Jensen, a senior research scientist at the Census Bureau, said last week.
Unlike the once-a-decade census, which determines how many congressional seats and Electoral College votes each state gets, as well as the distribution of $2.8 trillion in annual government funding, the population estimates are calculated from government records and internal Census Bureau data.
“So I have no reason to doubt the numbers that come out,” Frey said.
