Contrary to what some may believe, the majority of the world's Muslim population does not live in the Middle East. In fact, Pew research indicates that of the 1.57 billion Muslims in the world, approximately 942 million of them live in Asia while roughly 314 million live in the Middle East and North Africa (2009). However, it is important to note that the Middle East and North Africa does have the greatest percentage of Muslim-majority nations, according to the Pew Research Center (2009).
Approximately 1/5 of the world's Muslim population lives in nations which do not recognize Islam as the predominant religion (Pew Research Center, 2009). Pew also indicates that these minorities can actually be pretty large, such as the case with India, which holds the world's third largest Muslim population (2009)! It has also been found that Syria has less Muslims than China (Pew, 2009).
