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.
