What are the New Faiths? The New Faiths are identified with Asia. Dominant among them, in numbers and influence, are Islam, Hinduism, and Buddhism, with Sikhism a distant fourth. While all population estimates are provisional, Muslims world-wide are perhaps 1.2 billion, Hindus 790 million, Buddhists 365 million, and Sikhs 25 million. The numbers in the USA are fractional, and far less than the second American religion, Judaism, except in the case of Islam.
