The U.S. Census Bureau's latest population estimates show a significant slowdown in population growth across the country, driven by declining international migration and shifting domestic migration patterns. Between July 1, 2024, and July 1, 2025, the average growth rate for metro areas fell from 1.1% to 0.6%, marking a notable decline in population expansion.
Domestic Migration Shifts
The data reveals a continued redistribution of the population from large urban centers to less populous areas. Over 80% of counties in Tennessee, South Carolina, North Carolina, and Kentucky saw more people moving in than out, while states like California, Hawaii, and Florida experienced net domestic migration losses. Jasper County, South Carolina, and Brunswick County, North Carolina, had the highest positive net domestic migration rates, while Vernon Parish, Louisiana, and Miami-Dade County, Florida, saw the largest declines.
Metro Growth Declines
The slowdown in population growth was most pronounced in metro areas along the U.S.-Mexico border, where immigration levels dropped sharply. Laredo, Texas; Yuma, Arizona; and El Centro, California, saw the steepest declines in growth rates, attributed to reduced immigration. Meanwhile, Florida's Gulf Coast experienced population losses due to hurricanes, which prompted residents to leave.
National Trends
The Census Bureau noted that the U.S. population growth has slowed significantly, primarily due to a historic decline in net international migration. This trend is compounded by an aging population and declining birth rates, making migration a critical factor in population changes. The data reflects the initial months of President Donald Trump's second term, during which immigration policies were tightened.
Regional Variations
Despite the overall slowdown, some regions continued to grow. Ocala, Florida, and Myrtle Beach, South Carolina, were among the fastest-growing metro areas, driven by positive net domestic migration. However, most Florida metros grew at a slower pace than the previous year, with Miami experiencing a slight population decline.
