Projection

Values for 2100 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 2100

Ages 20–29 are wider than ages 0–4: the projected pyramid turns into a beehive as fertility nears replacement. Read the full analysis of Nigeria’s pyramid.
