Japan Population Pyramid 2035
Japan in 2035
United Nations projections (medium variant) put the population of Japan at 115,876,149 in 2035. Ten years before, in 2025, the projected population is still 123,103,479 — a ten-year decline of 5.9%.
With a projected median age of 53.5 years, Japan would have a youth dependency ratio of 17.6 and an old-age dependency ratio of 57.2 per 100 people of working age. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
