Major World Religions, 2010-2050

Source: Pew Research Center, “Religious Composit ion by Country, 2010-2050”, 2015 , 


Only the Pew Research Center compiles and calculates international data on religions. The graph shows the global number of adherents for each main religion in 2010, and the projections for 2050. Christians formed the greatest number in 2010 (over 2 billion), coming before Muslims and the unaffiliated, but Muslims will have almost caught up with Christians by around 2050 (a little under 3 billion). These changes are more due to regional demographic factors than to religious ones (conversions, etc.).
