Country database

Population pyramids by country, 1950–2100

Search 237 countries and areas. Every profile includes the same comparable UN series, age-by-sex table, and estimate/projection boundary.

Estimate or projection?

The UN series provides historical estimates through 2023. Figures from 2024 onward—including 2026—are medium-scenario projections, not counts or predictions guaranteed to occur.

Inside every profile

More than a single population pyramid

Eight age structures

Move from 1950 and 1975 through the last historical estimate in 2023, then examine medium projections for 2026, 2050, 2075, and 2100.

Exact age-by-sex data

Use the accessible table for population counts and shares in every five-year group from ages 0–4 through 100+.

Calculated change

See the largest cohorts, age dependency, change since 1950, projected 2050 direction, fertility, longevity, and comparable regional profiles.

Compare two places

Use the same measures side by side, without confusing population size with age structure.
