This list of largest religions includes all major religions in the world sorted by number of adherents.

List[edit | edit source]

The numbers below include all people who are recorded as identifying with the religion which means that some individuals will be counted twice. Notably this is the case for Jienism and Guidao with the majority of the Yingdalan population identifying with both religions. "No religion" is included in this table (highlighted in yellow) for comparative purposes even though it is not a religious tradition or belief system.
