Methodology

Source:: U.S. Census Bureau, American Community Survey 5-Year Estimates, 2024
Measure: Median Resident Age, ranked highest first across all U.S. counties (1,879 ranked in total).
Universe: Places below a 5,000-resident floor are excluded so a median computed on a handful of households cannot top the ranking.
Vintage: 2024
