The Africa Country Business Index (ACBI) is a tool that describes how businesses based in Africa and/or trading/investing across African countries perceive trade under the Free Trade Agreements that are already in force across African countries, including the African Continental Free Trade Area (AfCFTA). Differently from other integration indices, the ACBI is informed entirely by private-sector perceptions, built through online surveys and telephonic and face-to-face interviews. Launched by the United Nations Economic Commission for Africa (UNECA) in 2018, the Index targets three groups of countries, corresponding to the 3 phases of its implementation. Phase 1 covered Cameroon and Zambia, while phase 2 expanded the analysis to additional seven countries, namely: Angola, Côte d’Ivoire, Gabon, Kenya, Namibia, Nigeria and South Africa, all nations that have already signed, ratified and deposited their instrument of ratification for the AfCFTA. In the third phase, the Index will be rolled out in the Democratic Republic of the Congo, Egypt, Morocco, Rwanda, Senegal and Tunisia.
