South Is Only Region Where Population Is Still Growing in All Age Groups

The U.S. Census Bureau reported that the South was the only U.S. region to experience population growth across all five age groups between April 2020 and July 2025. During this period, the South's population increased by 6.0%, which is nearly double the national growth rate of 3.1%. Lauren Bowers, chief of the Census Bureau’s Population Estimates branch, attributed these regional age pattern shifts to the transition of baby boomers into retirement, combined with local migration and fertility trends. She noted that the South's gains in age groups that are declining or stagnant elsewhere underscore its strong positive migration patterns.

The South was the sole region to add residents under the age of 18, with its youth population growing by 1.1% from 2020 to 2025. In contrast, the Northeast saw a 4.1% decline, the Midwest a 3.9% decline, and the West a 5.7% decline in this age group. This indicates a growing appeal to families in the South. Furthermore, the South was the only region to experience growth among adults aged 45 to 64, with a 0.1% increase during the same timeframe. Other regions saw declines: the Northeast (-7.1%), Midwest (-6.2%), and West (-2.7%).

These demographic trends suggest the South is attracting residents across various life stages, from young families to those nearing retirement. The region's ability to foster growth in age groups that are shrinking in other parts of the country highlights its sustained demographic vitality. The Census Bureau's data indicates a significant migration into Southern states, influencing national population dynamics and reshaping the demographic landscape.
