where does islam rank in size on the list of the world’s religions
Islam by country Adherents of Islam constitute the world's second largest religious group. According to a study in 2015, Islam has 1.8 billion adherents, making up about 24% of the world population.[1] Most Muslims are either of two denominations: Sunni (80-90%, roughly 1.5 billion people)[2] or Shia (10â€“20%, roughly 170-340 million people).[3] Islam is the dominant religion in the Central Asia, Indonesia, Middle East, South Asia, North Africa, the Sahel[4][5][6][7] and some other parts of Asia.[8] The diverse Asia-Pacific region contains the highest number of Muslims in the world, easily surpassing the Middle East and North Africa.[9]
Religion in the United Kingdom According to the 2011 Census, Christianity is the majority religion, followed by Islam, Hinduism, Sikhism, Judaism and Buddhism in terms of number of adherents. Among Christians, Anglicans are the most common denomination, followed by the Catholics, Presbyterians, Methodists and Baptists. This, and the relatively large number of individuals with nominal or no religious affiliations, has led commentators to variously describe the United Kingdom as a multi-faith and secularised society.
