The U.S. Census Bureau released new population data for metropolitan areas and counties, showing faster growth in the southeastern United States. While many areas saw population increases, large cities and highly populated counties experienced slower growth rates due to a decline in net international migration nationwide.

Why it matters

The new census data provides insights into demographic shifts across the country, which can have significant implications for economic development, infrastructure planning, and the distribution of political representation and federal funding.

The details

The metropolitan area with the largest growth from 2024 to 2025 was Ocala, Florida, at 3.4%. Other fast-growing areas were located in South Carolina, North Carolina, and other parts of Florida. South Carolina and North Carolina had the highest statewide population growth in 2025. However, many large cities and more populous counties saw their growth rates slow due to a decline in net international migration, a key driver of population change. Domestic migration, births, and deaths also contributed to population shifts in different geographies.

  • The new data covers population changes from July 1, 2024, to July 1, 2025.
  • The 2025 Vintage estimates were released on Thursday, March 26, 2026.
