Summary

Japan in 2042

United Nations projections (medium variant) put the population of Japan at 110,692,358 in 2042. That would be 6.3% less than in 2032 (118,114,141).

With a projected median age of 54.1 years, Japan would have a youth dependency ratio of 20.0 and an old-age dependency ratio of 67.7 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
