Born, Died, Moved
What is moving each country’s population? Change the year and country to follow three flows.
- Color shows the combination of natural change and net migration, not magnitude.
- In the bands below, upward flows add people and downward flows remove them; the line is net population change.
- Years from 2024 are the UN medium projection. Future net migration follows UN assumptions, not an extrapolation of past data.
Population-change combination
2023 (actual) ／ 236 countries
Japan
Natural increase means births exceed deaths. Net inflow means arrivals exceed departures.
WPP records natural change or net migration as zero; this does not mean missing data.
Color shows direction only; magnitude is below. Countries without map boundaries: 9.

Source and data notes
United Nations, Department of Economic and Social Affairs, Population Division (2024). World Population Prospects 2024 · United Nations Terms of Use · Medium · Demographic indicators retrieved: 2026-08-17 · Deaths by single age retrieved: 2026-08-21
Net migration is the difference between people entering and leaving, not the number of migrants. It is zero-sum globally; WPP sets the world value to zero. Country sums differ by up to 4.989 thousand.
Net migration here differs from the migrant-stock visualization, which shows foreign-born residents with a different definition and reference date, so the values do not match.
These data show age at death only; they do not contain causes of death.
The world series covers 237 countries including Kosovo; maps and country views cover 236.
WPP values are in thousands. Displayed counts multiply them by 1,000, so final digits do not imply precision.
