Median Age by Country (2026)

The three oldest countries are Vatican City (56.2), Monaco (53.1), Saint Helena (51); the three youngest are Central African Republic (14.6), Somalia (15.6), Niger (15.7).

Across all 238 countries the median is 33.3 years and the simple (unweighted) average is 32.3; the spread from 14.6 to 56.2 shows how differently countries fare on this measure.

By continent, the leaders are Japan in Asia (50.2), Vatican City in Europe (56.2), Saint Helena in Africa (51), Martinique in North America (50.2), Falkland Islands in South America (43.4), Palau in Oceania (38.9).

The median age divides a population into two equal halves. It is a compact way to compare how young or old countries are: Niger and Uganda have medians under 18, while Japan, Italy and Monaco are above 48.
