INDPRIDE

The world's third largest religion, Hinduism, makes up the majority of the population of 3 nations:
Balinese-style Hindus also make up 95% of the large population of Bali, in Indonesia.

Nepal
India
Mauritius
Bali, Indonesia

It is interesting to note that although the majority of the world's Hindus live in India, the nation as a whole is only about 80% Hindu, and is an officially secular state, i.e., there is no state religion.

In Nepal a higher proportion of the population are Hindus than in India, and Nepal is the world's only official Hindu state. Freedom of worship is protected, but official state religion is Hinduism. (As in many countries, inter-religious proselyting is prohibited.)

In Mauritius, a bare majority of 52% of the population are Hindu.

Buddhism

The worlds' fourth largest organized religion, Buddhism, is the religion of the majority of the population in 10 countries:

Thailand
Cambodia
Myanmar
Tibet
Bhutan
Mongolia
Sri Lanka
Laos
Vietnam
Japan

Buddhism is also very important historically and culturally in other several other Asian countries, but is no longer cited as the preferred religion by at least 50% of the population. In China and North Korea, Buddhism was forcibly suppressed by Communist regimes. Buddhism remains important in these countries, but is no longer claimed as the religious preference by the majority of the population. Taiwan is heavily Buddhist, but the religion is mixed with Taoism and Confucianism, and exists side by side with other religions to such an degree that Buddhism is probably not a majority religion, strictly speaking. In South Korea Christianity has recently made enough gains that Buddhism is no longer the religion of the majority of the population.

Currently, many people in traditionally Buddhist countries such as Korea and China are embracing Christianity in greater numbers, while Buddhism is in turn gaining increasing numbers of converts among Westerners in places such as Europe, Australia, and the United States. There are even organizations and books for "JuBus" (Jews who practice Buddhism).

Judaism

Jews makes up the majority (83%) in one country: Israel.

A large number of Israel's Jews are secular -- nonobservant and either philosophically nonreligious or even agnostic or atheist. Religious Jews are in the minority in Israel.

Interestingly enough, a larger number of Jews live in the United States than in Israel, and a higher proportion of American Jews are religious (i.e., practice Judaism or profess some form of belief in Judaism).

Taoism and Confucianism

No country can really said to be predominantly Taoist or Confucian in the sense that a majority of people claim one of these systems as their religion. But Taoism and Confucianism (mixed with Buddhism) are major cultural and philosophical influences in many East Asian nations. Religious Taoism in still very significant in Taiwan.

Many writers have noted that the influence of Confucianism is felt more significantly in present-day Japan than Buddhism, Shinto, or any other religion, even though no Japanese people cite it as their "religion." The majority of Chinese are influenced by combinations of Confucian and Taoist thought, and traditional religious practices and beliefs (ancestor- and nature-oriented), but most do not name themselves exclusively as adherents of these traditions. Other important influences and religions in China which are of non-Chinese origin are Buddhism, Communism, Islam, and Christianity.

Baha'i

There are no nations, provinces or states where Baha'is make up a majority of the population. This is not surprising, as the religion is very young.

There are some villages in Africa which are predominantly Baha'i. (It is not unusual for smaller, close-knit villages in Africa, and sometimes other parts of the world, to adopt a new religion en masse.)

Shinto

Because of historical birth registration laws and customs, Shinto organizations claim over 80% of the population of Japan as adherents. (Keep in mind that Buddhist organizations claim 90% of the population as adherents.) The majority of Japanese take part in Shinto celebrations, festivals, etc., and many have Shinto shrines in their homes. Although less than 4% of Japanese claim Shinto as their religious preference in opinion surveys (most claim Buddhism, and most also say they aren't religious), the religion of Shinto can certainly be said to "have a state." But the religion's influence is more cultural, historical, and traditional--more comparable to the influence of the Anglican Church in England than Islam in Saudi Arabia.

Japan

Sikhism

Sikhism does not make up the majority of the population of any nation. It makes up the majority of the population of one Indian Province: Punjab.

Jainism

There are no countries or provinces in which Jains make up the majority of the population. Jains have no significant, established communities outside of India.

Zoroastrians

The relatively few remaining Zoroastrians in the world do not make up the majority of the population in any countries, states, or provinces. They do form the majority in a few small Iranian towns, and they are an important segment of the cultural elite in a few major Indian cities.

Zoroastrianism was once the state religion of ancient Persia (present-day Iran), and at one time was one of the largest organized religions in the world.
