The practice of vegetarianism is strongly linked with a number of religious traditions worldwide. These include religions that originated in India, such as Hinduism, Jainism, Buddhism, and Sikhism. With close to 85% of India's billion-plus population practicing these religions, India remains the country with the highest number of vegetarians in the world. [citation needed]
