Hinduism estimated to have 1.2 billion followers and Buddhism over half a billion. They are both syncretic in structure. About 90% of Hindus live in India with significantly smaller numbers in Nepal, Sri Lanka, and Bali -- plus converts overseas. The Roma people, although originating in north central India, cannot technically be considered part of the Hindu diaspora. In contrast, Buddhism is spread throughout East Asia. It affected every country including China and Indonesia, the two largest in population. Buddhism is more messianic (recruits through missionaries) while Hinduism is a religion in which one must undergo a series of steps for conversion. Neither spread through military means.
