Summary

Japan in 2040

United Nations projections (medium variant) put the population of Japan at 112,158,304 in 2040. Compared with 2030, when the projection stands at 119,584,122, that represents a decline of 6.2% over ten years.

Half of the population would be younger than 54.0 years, with 10.4% children under 15 and 35.3% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
