Good to know
- Everyone living in the country on 1 July of each year.
- Source: UN DESA, World Population Prospects 2024.
- Before 1950: HYDE (2023), Gapminder (2022) and UN WPP (2024), via Our World in Data.
- 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.
