Growth slows across U.S. counties as immigration plummets

"The nation's largest counties ... are often international migration hubs, gaining large numbers of international migrants and losing people that move to other parts of the country via domestic migration."

"With fewer gains from international migration, these types of counties saw their population growth diminish or even turn into loss."

"California's Los Angeles County lost nearly 54,000 people from 2024 to 2025, down about -0.6%. It remains the biggest U.S. county, with about 9.7 million people."

"The U.S. overall still grew by 0.5% between 2024-25, but that's down from 1% over the previous period."

International migration decreased in nine out of ten U.S. counties between 2024 and 2025, according to the Census Bureau. This decline particularly affected populous areas, which are typically migration hubs. Los Angeles County lost nearly 54,000 residents during this period, reflecting a broader trend of diminished population growth in large counties. Overall, the U.S. population grew by 0.5%, down from 1% previously, with international migration dropping from 2.8 million to 1.3 million, a 55% decrease. Natural population change remained stable.
