Hinduism has approximately 1.17 billion adherents worldwide (14.9% of the world's population). Hinduism is the third largest religion in the world, behind Christianity (32.8%) and Islam (23.3%). Pew Research Center data shows the global Hindu population grew steadily from 2010 to 2020 and is expected to keep rising. This increase is driven largely by higher fertility rates in India and Nepal and by growing Hindu populations in regions receiving more migrants.
The two Hindu-majority countries are India and Nepal and together account for more than 95% of the Hindu population worldwide. The past two centuries have seen large-scale migration of Hindus from Southeast Asia, to around the world. Countries with more than 500,000 Hindu residents and citizens are (in decreasing order) India, Nepal, Bangladesh, Indonesia, Pakistan, Sri Lanka, the United States, Malaysia, United Kingdom, Myanmar, Australia, Mauritius, South Africa, Canada, and the United Arab Emirates. Global data shows Hinduism is still concentrated in South Asia, but significant communities also exist in Southeast Asia, the Caribbean, and Oceania. WorldData.info reports that India holds most of the world’s Hindus, with notable populations in Nepal, Bangladesh, and Indonesia.
