How to read these figures
Country indicators on Africa Center are point-in-time estimates that are revised when new census or survey data is published. GDP is reported here as nominal US dollars at current exchange rates, which is the format most widely used by international institutions for cross-country comparison; for the difference between this and the purchasing-power-parity variant, and why GDP rankings reorder between releases, see reading African economic data. Per-capita figures divide GDP by population and are most useful when read alongside the absolute total. Definitions for every indicator are in the glossary; the rules we follow when sources disagree are written up in the methodology.
