Each country on its own
Good to know
- How fast the population grew or shrank in a year: births minus deaths, plus people moving in minus people moving out.
- Source: UN DESA, World Population Prospects 2024.
- The dashed line is the UN projection (medium variant), a scenario rather than a forecast; the band is its 95% prediction interval.
- Ranks count the 229 countries with a value in 2023, highest first.
- The faint line is the world as a whole, as the same source counts it.
