Although Hinduism is practiced in many countries around the world, the vast majority of Hindus (97 percent) live in India, Nepal and Mauritius, where the religion is more common than any other. Of these three nations, India has the largest Hindu population. The words India and Hinduism have the same derivation, the Indus river, which is where the religion originated.
As of 2010, Hinduism had approximately 1 billion followers worldwide, equating to around 15 percent of the global population. However, unlike followers of other major world religions, Hindus worship a wide variety of deities. While all of these are quintessentially manifestations of a single source, Brahman, their worship gives rise to numerous different traditions around the world.
