Estimated size of Christian traditions in world population:

Catholic – 15%

*“Other Christian” groups self-identify as Christian although older Christian traditions may view them as distinct from mainstream Christianity, e.g., the Church of Jesus Christ of Latter-day Saints (Mormons), Jehovah’s Witnesses, and the Christian Science Church.
