Older Adults Outnumber Children in Nearly Half of U.S. Counties in 2024

The aging population is reshaping the demographic landscape of the United States. As of 2024, older adults now outnumber children in nearly half of U.S. counties—a reflection of long-term trends in longevity, birth rates, and migration. This demographic shift holds significant implications for public planning, healthcare, and local economies. With more counties tipping toward an older majority, the way we structure services and community support must evolve accordingly.
