About This Dataset

Countries by Median Age 2025

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.

Analysis

Monaco heads the table on 55.4, ahead of Japan (49.5) and Germany (46.6) in Median Age (Years) in 2025. 12.3 separates the highest figure (55.4) from the lowest (43.1) in Median Age (Years). First and second are separated by 5.90, so the leader sits inside the field rather than apart from it. Places 3 to 8 are close together, spanning 46.6 to 43.1 Median Age (Years).
