Summary

Japan in 2029

By 2029, the population of Japan is expected to reach 120,308,089. Compared with 2019, when the projection stands at 126,699,424, that represents a decline of 5.0% over ten years.

With a projected median age of 52.1 years, Japan would have a youth dependency ratio of 18.0 and an old-age dependency ratio of 52.6 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.
