The Pew Research Center's report on the global Muslim population estimates that there are 1.57 billion Muslims, comprising 23% of the world's population, with over 60% residing in Asia. The report highlights significant minority populations in countries like India and China, and provides detailed demographic data on sectarian identities, with 87-90% of Muslims identified as Sunni and 10-13% as Shia. Additionally, the report lays the groundwork for future studies on Muslim population growth and the intersection of religion and public life.
