The report provides an updated portrait of the centenarian population in the United States based on the 2020 Census.

The age profiles of states and communities don’t always mirror the national picture.

See how the total population and race and ethnicity groups have changed over time for the nation, states, metropolitan areas, micropolitan areas, and counties.

This report presents key findings from the 2020 Census on the age and sex composition of the U.S. population as well as changes between 2010 and 2020.

From 2014 to 2024, the share of older mothers rose as fewer teens and women in their 20s and 30s had children.

Less than 25% of 25- to 34-year-olds lived outside their parental home, worked, were married and had kids in 2024, down from almost half in 1975.

A state’s median age does not tell the whole story. Florida has the fifth highest median age yet also has counties younger than the national median.

Median age rose in 85% of the nation’s 387 metro areas from 2020 to 2024 and was higher than the national median of 39.1 in almost half of metro areas.

In 2024, 6.3 percent of American Indian and Alaska Native individuals aged 18+ were veterans.
