Cambodia vs. World
In 2024, Cambodia's annual population change, fertility and median age do not all sit on the same side of the world benchmarks: they are respectively higher than, above and younger than the global benchmarks.
| Indicator | Cambodia | World | Year |
|---|---|---|---|
| Annual population change | +1.23% | +0.87% | 2024 |
| Total fertility rate | 2.5 | 2.25 | 2024 |
| Median age | 26 | 30.6 | 2024 |
The table deliberately uses one 2024 source context for Cambodia and the world. This avoids combining national figures from one year with global figures from another.

Sources & methodology
This profile uses United Nations World Population Prospects 2024 as the primary framework for globally comparable population, age, fertility and projection data. The World Bank is the primary source for the female population share. Some country values were accessed through secondary retrieval interfaces that republish or organize UN data; those interfaces are identified below as secondary and are not treated as the original statistical publishers.
