More Counties Saw Population Gains in 2023

MARCH 14, 2024 – More U.S. counties experienced population gains than losses in 2023, as counties in the South saw faster growth and more Northeast and Midwest counties had population losses turn to gains, according to the U.S. Census Bureau’s Vintage 2023 estimates of population and components of change released today.

Percent change in county population: July 1, 2022 to July 1, 2023

Approximately 60% (1,876) of U.S. counties gained population from 2022 to 2023, an increase from the 52% of counties (1,649) that experienced population growth between 2021 and 2022. Among the nation's 3,144 counties, the average change from 2022 to 2023 was 0.29%, up from 0.17% the previous year.

“Domestic migration patterns are changing, and the impact on counties is especially evident,” said Lauren Bowers, chief of the Census Bureau’s Population Estimates Branch. “Areas which experienced high levels of domestic out-migration during the pandemic, such as in the Midwest and Northeast, are now seeing more counties with population growth. Meanwhile, county population growth is slowing down out west, such as in Arizona and Idaho.”
