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.
