Japan Population Pyramid 2099
Japan in 2099
United Nations projections (medium variant) put the population of Japan at 77,230,866 in 2099. That would be 4.7% less than in 2089 (81,013,198).
Half of the population would be younger than 53.9 years, with 11.5% children under 15 and 37.4% aged 65 or older. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
