A nation divided
Voice of the Martyrs, a Christian advocacy group, says the split is Christian 51.3%, Muslim 45.1%. The Central Intelligence Agency’s World Factbook estimates it at 50 percent Muslim, 40 percent Christian. A 2009 Pew Forum report says the Muslim population is 50.4 percent. According to a 2010 report, in the last national census, 47.20% were Muslims. The government officially quit collecting religious information in 1963.
