A 2012 report on religion and public life by the Pew Research Center stated that in 2010, 49.3 per cent of Nigeria's population was Christian, 48.8 per cent was Muslim, and 1.9 per cent were followers of indigenous and other religions or unaffiliated. However, in a report released by Pew Research Center in 2015, the Muslim population was estimated to be 50%, and by 2060, according to the report, Muslims will account for about 60% of the country. The 2010 census of Association of Religion Data Archives has also reported that 48.8% of the total population was Christian, slightly larger than the Muslim population of 43.4%, while 7.5% were members of other religions. However, these estimates should be taken with caution because sample data is mostly collected from major urban areas in the south, which are predominantly Christian.
