There is a wide disparity in GHI scores across Africa, ranging from 6.2 in Tunisia to 49.9 in Burundi, indicating a stark divide in countries’ economic well-being.
Countries naturally group into lower (below 20), mid (20–34.9), and high (35+) ranges, reflecting varying levels of economic strain.
West and Central African countries like Nigeria (32.8), Niger (33.9), Chad (34.8), and the Central African Republic (33.4) cluster toward the upper end, indicating deeper economic challenges.
Extreme cases remain concentrated in fragile states; the highest scores — Somalia (42.6) and Burundi (49.9) — highlight persistent structural vulnerabilities, often linked to conflict and instability.
