Ranked over 1 of 55 African countries — those whose works have been swept. This is a ranking within that set, not a continental one, and an institution's absence usually means its country has not been swept yet. Institutions with fewer than 50 publications in the window are excluded: a share computed on a handful of works ranks noise, not behaviour.
Open access, 2022–2025 · institutions under 50 publications excluded
