Statistics of the world's religions are only very rough approximations. Aside from Christianity, few religions, if any, attempt to keep statistical records; and even Protestants and Catholics employ different methods of counting members.
Rank | Religion | Members |
1. | Christianity | 2.3 billion |
2. | Islam | 1.8 billion |
3. | Unaffiliated | 1.2 billion |
4. | Hinduism | 1.1 billion |
5. | Buddhism | 500 million |
6. | Folk religions | 400 million |
7. | Other religions | 100 million |
8. | Judaism | 10 million |
