A new Pew Research Center study reveals Muslims as the fastest-growing religious group globally between 2010 and 2020, increasing by 347 million. This growth, surpassing all other religions combined, is primarily attributed to higher birth rates in regions like the Middle East-North Africa, sub-Saharan Africa, and the Asia-Pacific. The study highlights that this growth is not significantly driven by conversions to or away from Islam.
