Questions

Which country in Africa has the most polluted air?
Nigeria has the most polluted air in Africa: 65.7 µg/m³ (2023). Next come Niger (65.2 µg/m³) and Cameroon (55.6 µg/m³).
Which country in Africa has the cleanest air?
The Seychelles, with 9.3 µg/m³ (2023).
What is the typical air pollution (pm2.5) of a country in Africa?
The median of the 54 countries in Africa is 26.9 µg/m³: half are above it, half below. The median, not the average, because a few countries at the top would drag an average far above almost everyone.
Where do the figures come from?
The average concentration of fine particles (PM2.5) in the air people breathe over a year, in micrograms per cubic metre. The WHO’s guideline is 5. Source: World Bank, 2023. Only independent states are ranked; territories are listed separately. A country’s continent follows Natural Earth; the handful of island states it files under the open ocean are placed by their UN subregion.
