Projection

Values for 2050 come from the UN World Population Prospects 2024 medium scenario. They depend on assumptions about fertility, mortality, and migration and are not forecasts guaranteed to occur.

What to notice in 2050

The widest band is 75–79 as the second boom ages, and women heavily outnumber men above age 80. Read the full analysis of Japan’s pyramid.
