Census Counties Metro Population

New population estimates show that U.S. growth in metro areas slowed sharply as immigration dropped and hurricanes pushed people out of some Gulf Coast counties. The U.S. Census Bureau reports that the average metro growth rate fell from 1.1% in 2024 to 0.6% in 2025. The data covers a one-year period ending in July 2025. Metro areas along the U.S.-Mexico border saw the steepest declines as the number of immigrants fell. Big immigration hubs also saw significant drops. Miami-Dade County, Harris County in Texas and Los Angeles County all took in far fewer immigrants last year.
