Historical observations

Countries & territories

Same-year values. Equal values share a rank.

Sources & method

Ranks cover available countries and territories, using the same indicator, source unit and reference year. Unrounded source values determine ties. Coverage is not a sovereign-country or complete global ranking; national definitions may differ. Missing values and other years are excluded. The information icon preserves the original number, unit and evidence.
