According to historical estimates from the World Religion Database, in 1900, just 14% of the people living in Sub-Saharan Africa practiced Christianity; even fewer were Muslim (9%). Today, however, Africa is overwhelmingly populated by followers of these two religions. The number of Christians has grown 70-fold, and now a majority of Sub-Saharan Africans are Christian (57%). The Muslim population has grown 20-fold, and now nearly three-in-ten (29%) Sub-Saharan Africans are Muslim. Just 13% are followers of traditional African religions.
