Japan Population Pyramid 2030
Japan in 2030
In 2030, Japan is projected to have a population of 119,584,122 people. Ten years before, in 2020, the projected population is still 126,304,543 — a ten-year decline of 5.3%.
The median age is projected at 52.4 years, with 17.8 children under 15 and 53.3 people aged 65 or over for every 100 people of working age (15–64). This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
