America’s population grew by just half a percent in the Census Bureau’s latest one-year estimate, reflecting what the agency called a “historic decline” in immigrants managing to reach and settle in the U.S.
The country grew by only 1.8 million people between July 1, 2024, and July 1, 2025, the bureau said.
That’s the slowest rate of growth since the early days of the coronavirus pandemic. It’s also a massive reversal from the 2023-24 period, when the country added 3.2 million people, the fastest growth in nearly two decades.
The difference, analysts said, was the change from massive immigration in the Biden era to the precipitous decline the country is seeing now. The country netted 2.7 million people from international migration in the year that ended in the summer of 2024, compared with just 1.3 million in 2025.
The data for the latest year still includes more than six months under President Biden. Projecting current trends under President Trump out, the Census Bureau predicted net population growth due to migration will dip to 321,000 as of this coming July.
“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,” said Christine Hartley, assistant division chief for Estimates & Projections at the Census Bureau.
The country’s total population as of July 1, 2025, stood at 341.8 million.
California saw its population dip by about 9,000 people but was still tops in the nation with 39.4 million people. Texas, in second place, grew by nearly 400,000 people, ending at 31.7 million.
Florida saw a big drop in internal migration. Neighboring Alabama actually won more domestic newcomers than Florida.
But foreign immigration meant the Sunshine State still grew by nearly 200,000 people, reaching 23.5 million.
