Sub-Saharan Africa Religion Survey, 2010

DOI

10.17605/OSF.IO/R9CTN

Summary

"The vast majority of people in many sub-Saharan African nations are deeply committed to the practices and major tenets of one or the other of the world's two largest religions, Christianity and Islam. Large majorities say they belong to one of these faiths, and, in sharp contrast with Europe and the United States, very few people are religiously unaffiliated. Despite the dominance of Christianity and Islam, traditional African religious beliefs and practices have not disappeared. Rather, they coexist with Islam and Christianity. Whether or not this entails some theological tension, it is a reality in people's lives: Large numbers of Africans actively participate in Christianity or Islam yet also believe in witchcraft, evil spirits, sacrifices to ancestors, traditional religious healers, reincarnation and other elements of traditional African religions."

Explore "key findings from more than 25,000 face-to-face interviews conducted on behalf of the Pew Research Center's Forum on Religion & Public Life in more than 60 languages or dialects in 19 sub-Saharan African nations from December 2008 to April 2009. [...] The countries were selected to span this vast geographical region and to reflect different colonial histories, linguistic backgrounds and religious compositions. In total, the countries surveyed contain three-quarters of the total population of sub-Saharan Africa." (Full Report)
