<P> Religion in Nigeria (2016) </P> <P> Nigeria, the most populous African country (with a population of over 182 million in 2015), is nearly equally divided between Christianity and Islam, though the exact ratio is uncertain . There is also a growing population of non-religious Nigerians who accounted for the remaining 5 percent . The majority of Nigerian Muslims are Sunni and are concentrated in the northern region of the country, while Christians dominate in the south . The Pew Forum in a 2010 report compared reports from several sources . The 1963 Nigerian census found that 36% of the population was Christian, 38% Muslim, and 26% other; the 2008 MEASURE Demographic and Health Survey (DHS) found 53% Muslim, 45% Christian, and 2% other; the 2008 Afrobarometer poll found 50% Christian, 49% Muslim, and 1% other; Pew's own survey found 52% Muslim, 46% Christian, and 1% other . </P> <P> Most of Nigeria's Christians are Protestant (broadly defined) though about a quarter are Catholic . From the 1990s to the 2000s, there was significant growth in Protestant churches, including the Redeemed Christian Church of God, Winners' Chapel, Christ Apostolic Church (the first Aladura Movement in Nigeria), Deeper Christian Life Ministry, Evangelical Church Winning All, Mountain of Fire and Miracles, Christ Embassy, The Synagogue Church Of All Nations, The CommonWealth Of Zion Assembly (COZA), the Aladura Church (indigenous Christian churches being especially strong in the Yoruba and Igbo areas), and of evangelical churches in general . These churches have spilled over into adjacent and southern areas of the middle belt . Denominations like the Seventh - day Adventist also exist . </P>
