Key insights

Demographic profile

Japan presently shows a constrictive pyramid, narrower at the base than in the middle, reflecting sustained sub-replacement fertility and population ageing. The median age in 2024 is 50.4 years.

Age composition

Children under 15 account for 11.4% of the population; people 65 and older account for 29.8%.

Peak population

Japan's population peaked in 2009 and has been declining since.

Long arc

In 1950 the population was 86.4 million with median age 22.4. Projected 2100 values are 76.8 million and median age 54.
