Sub-Saharan Africa, which includes 50 countries and territories, has about 241 million Muslims, which is about 15% of the world Muslim population. Nigeria has the largest Muslim population in Sub-Saharan Africa, with about 78 million Muslims (about 50% of Nigeria’s total population). Almost one-in-three Muslims (about 32%) in Sub-Saharan Africa live in Nigeria. Western Africa is the only area in Sub-Saharan Africa with a Muslim majority. In contrast, the southern part of Africa has the smallest Muslim population.

Sub-Saharan Africa is also home to a number of countries that have very large Muslim majorities. Countries with the highest percentages of Muslim populations are: Mauritania (99%), Niger (99%), Somalia (99%), Mayotte (98%), Comoros (98%), Djibouti (97%), Senegal (96%), Gambia (95%), Mali (93%), Guinea (84%) and Sierra Leone (71%). The combined Muslim population of all these countries is about 67 million, or about 4% of the global Muslim population.
