Older adults now outnumber children in 11 states and almost half of the counties in the U.S.

The U.S. population age 65 and older rose by 3.1% (to 61.2 million) while the population under age 18 decreased by 0.2% (to 73.1 million) from 2023 to 2024, according to the Vintage 2024 Population Estimates released today by the U.S. Census Bureau.

The data show the population continued to age, with the share of the population age 65 and older steadily increasing from 12.4% in 2004 to 18.0% in 2024, and the share of children declining from 25.0% to 21.5%.

As recently as 2020, there were just three states where older adults outnumbered children. By 2024, this number had increased to 11.

Similarly, from 2020 to 2024, the number of U.S. metro areas with more older adults than children increased from 58 to 112. This represents nearly 30% of the nation’s 387 metro areas.

In 2020, 31.3% (or 983) of the nation’s 3,144 counties had more older adults than children. This figure increased to almost 45% (1,411 counties) in 2024.
