How are these comparisons calculated?
Live populations extrapolate the UN World Population Prospects baseline with each country's growth rate; every other figure is the latest value published by World Bank Open Data (or the UN for median age, infant mortality and migration). Each row shows the year of the figure, and the charts below overlay the full historical series of both countries.

Sources & method: live populations are linear extrapolations of the UN World Population Prospects estimates; all other indicators are the latest values from World Bank Open Data (UN WPP for median age, infant mortality, sex ratio and net migration). Figures are statistical estimates, not census counts. Page generated 2026-10-20. More about our data.
