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.
