The Ibrahim Index of African Governance (IIAG) is a tool that measures and monitors governance performance in African countries. The IIAG governance framework comprises four categories: Safety \& Rule of Law, Participation \& Human Rights, Sustainable Economic Opportunity and Human Development. These categories are made up of 14 sub-categories, consisting of 100 indicators. The IIAG is refined on an annual basis. Refinements may be methodological, or based on the inclusion or exclusion of indicators. Different IIAG datasets are not comparable between themselves as they cover a different ten-year period, data are revised retrospectively, and the theoretical framework is updated between iterations. Users of the Index should therefore always reference the most recent version of the IIAG dataset.
