This document summarizes 16 maps showing the global distribution of adherents to various world religions and beliefs. It provides the key statistics on the number of adherents for each religion mapped, including their predominant geographical regions. The concluding section discusses how studying different beliefs can be worthwhile but cautions against doing so without critical thinking.

4. 367 Sunni Muslims : The size of each territory indicates the number of adherents to the Sunni denomination of Islam. Sunni Muslim adherents account for two thirds of the population in Northern Africa, 35% in the Middle East, 30% in Asia Pacific, 25% in both Southern Asia and Eastern Europe (including Turkey), and 22% in East and South Africa. Just over a billion people are believed to be adherents (i.e., practicing followers) of the main Sunni denomination of the religion of Islam.

5. 368 Shia Muslims The size of each territory indicates the number of adherents to the Shia denomination of Islam. Shia Muslims constitute a quarter of the population of the Middle East, but no more than 6% in any other region. Just over half of all Shia Muslims in the Middle East live in the Islamic Republic of Iran. Shia Muslims comprises some 15% of Muslims worldwide. Other groups are much smaller. Shia Muslims differ from Sunni Muslims in also following the religious guidance of Muhammad’s family, who are referred to as the Ahl al-Bayt, and certain of his descendants, known as Shi'a Imams.

6. 369 Catholic Christians . The size of each territory indicates the number of adherents to the Catholic denomination of Christianity.

Catholic Christians account for some 80% of the population in South America, 60% in Central Africa, 55% in North America, 50% in Western Europe, and 28% in Eastern Europe.

7. 370 Protestant Christians: The size of each territory indicates the number of adherents to the Protestant denominations of Christianity.

Just two percent of the population of North America and one percent of the population of the Middle East adhere to Judaism.

10. 373 Hindus : The size of each territory indicates the number of adherents of Hinduism. There are over 820 million adherents of Hinduism, almost all of them in India or Nepal. Hinduism as a conglomeration is the world's third-largest religion after Christianity and Islam, and the largest of the Dharmic religions, which originated in the Indian subcontinent and also include Jainism, Buddhism and Sikhism. Almost 60% of the population of South Asia adhere to Hinduism, but no more than two percent of the population of any other region.

The 23rd Tirthankar is the earliest who can be dated and lived about 3000 years ago. Outside of India the largest groups of Jains are found in Kenya (61 thousand), Tanzania (8 thousand), the United States (7 thousand), Nepal (6 thousand), Myanmar (3 thousand) and Uganda (2 thousand).

14. 377 Taoic Religions : The size of each territory indicates the number of adherents to various Taoic religions. About 390 million people are adherents of the various Taoic religions, including Confucianism, Shintoism, Taoism itself and Chinese Universalism. Nine out of every ten adherents to Taoic religions live in China. Taoism itself was founded by Lao-Tse, a contemporary of Confucius, and is most common in Taiwan. Confucianism is concentrated in China, as is Chinese Universalism, which has by far the most adherents (380 million). This map also includes the 2.8 million adherents of Shintoism, most of whom live in Japan.

15. 378 Baha'i : The size of each territory indicates the number of adherents of the Baha'I religion. There are just over 7 million adherents of the Baha'i faith worldwide. Baha'i is one of the youngest of the world's major religions, founded in 19th century Persia (now Iran) by Bahá'u'lláh (1817-1892). Baha'I teachings include abandoning all prejudice, eliminating extremes of poverty and wealth, and realizing universal education. By region the Baha'i faith is most popular in Central Africa where 0.5% of the population are adherents. By country, however, the largest numbers of followers are found in India (1.8 million), the United States (800,000), Iran (400,000), and Viet Nam (350,000). Overall the Baha'i religion is one of the most evenly distributed worldwide.

16. 379 Pagans : The size of each territory indicates the number of adherents to various pagan religions. There are thought to be about 240 million people worldwide who adhere to various pagan religions, including animists, spirit-worshippers, ancestor-worshippers, shamanists, polytheists, pantheists, cargo cults, and tribal messianic movements. Many of these religions are confined to a single tribe or people. Virtually all pagans live in Africa and Asia. Pagans constitute one in seven people in South and East Africa, one in nine in Northern Africa, one in eighteen in Central Africa. “There is a respect for all of life and usually a desire to participate with rather than to dominate other beings.” Prudence Jones, The Pagan Federation (at some point in the 2000s)

17. 380 Spiritualists : The size of each territory indicates the number of adherents of Spiritualism. Spiritualism has some 13 million adherents. Spiritualism is a philosophical doctrine, established in France in the mid-nineteenth century based on a series of books written by French educator Hypolite Léon Denizard Rivail (1804-1869) under the pseudonym Allan Kardec. On the lid of Rivail's burial chamber in Paris is written “ Naitre, mourir, renaitre encore et progresse sans cesse, telle est la loi ” "To be born, die, still to reappear and progress unceasingly, such is the law." Tombstone of Allan Kardec, 1869

18. 381 Agnostics : The size of each territory indicates the number of people living there who are believed to be agnostic as concerns religion. Some 770 million people are thought to be agnostics. Agnosticism is not a religion. Agnostics are people who believe either that it is not possible to have certain knowledge of the existence of a god or gods, or alternatively that while individual certainty may be possible, they personally have no such certainty ( or just can’t decide either way ). Agnostics do not deny the possibility of the existence of a god or gods but are not themselves adherents of any faith. The most agnostics live in China (540 million), the United States (28 million), Russia (26 million), then Germany (15 million), and then Japan (13 million).

19. 382 Atheists : The size of each territory indicates the number of people living there who are believed to be atheistic as concerns religion. Some 150 million people worldwide are thought to be atheists, with almost three quarters of them living in East Asia. Atheism is not a religion but an absence of belief in the existence of a god or gods, or a dismissal of such beliefs as illogical. There are many different kinds of atheism. Indeed some religions do not advocate belief in any god and their followers could therefore be considered atheists. Some forms of Buddhism, for example, are sometimes classified as atheistic (but not here).
