what is the percentage of shia and sunni
Shia–Sunni relations The present demographic breakdown between the two denominations is difficult to assess and varies by source, but a good approximation is that 85–90% of the world's Muslims are Sunni[1] and 10–15% are Shia,[2][3] with most Shias belonging to the Twelver tradition and the rest divided between many other groups.[2] Sunnis are a majority in most Muslim communities: in Southeast Asia, China, South Asia, Africa, and most of the Arab world. Shia make up the majority of the citizen population in Iraq, Bahrain, Lebanon, Iran and Azerbaijan, as well as being a politically significant minority in Pakistan, Syria and Yemen. Azerbaijan is predominantly Shia; however, practicing adherents are far fewer.[4] Indonesia has the largest number of Sunni Muslims, while Iran has the largest number of Shia Muslims (Twelver) in the world. Pakistan has the second-largest Sunni population in the world, while India has the second-largest Shia Muslim (Twelver) population.[5][6][7][8][9][10][11][12][13]
Religion in Nigeria Nigeria, the most populous African country (with a population of over 182 million in 2015),[3] 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.[4] 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.[4][5][6]
