Religion Members Percentage
Christianity 2.1 billion 33.0%
Islam 1.3 billion 20.1
Hinduism 851 million 13.3
Buddhism 375 million 5.9
Sikhism 25 million 0.4
Judaism 15 million 0.2%
Baha'ism7.5 million 0.1
Confucianism 6.4 million 0.1
Jainism 4.5 million 0.1
Shintoism 2.8 million 0.0
NOTES: As of mid-2004. This list includes only organized religions and excludes more loosely defined groups such as Chinese or African traditional religions.
