Muslims number 1.8 billion people worldwide (2015), representing 24% of global population. The overwhelming majority (87-90%) of Muslims are Sunnis; about 10-13% are Shi’a Muslims.

The countries with the five highest Muslim populations are all in South and Southeast Asia or in sub-Saharan Africa, rather than the Middle East. In India, which has the second-largest Muslim population, Islam is a minority religion (making up 15% of the country’s population) and Hinduism is the majority faith.

*Muslim population figures are notoriously inaccurate; Muslims cover a broad range of ancestries, such as Asian, African and Middle Eastern and they all have different practices and political outlooks.
