Muslims number 1.6 billion and make up 26% of the world's population, according to the Pew Research Center. And with almost a billion Muslims, Asia/Pacific has more than 3 times more Muslims than the Middle East. The report also includes Muslim beliefs about Sharia, morality, and politics. Thanks to F.C.
