About: Countries by Median Age 2025
Overview of the data behind this chart
Countries ranked by the median age of their population in 2025 according to UN World Population Prospects data. Monaco and Japan have the world's oldest populations by median age — a consequence of ultra-low birth rates, high life expectancy, and in Monaco's case a wealthy resident base that disproportionately attracts older retirees seeking favourable tax conditions, pushing its median age above 55.
