As of 2020, India has an approximate population of 1.32 billion people. With so many people, India has become a tapestry of different cultures and religions over the centuries. Some religions, such as Sikhism, even originated there. Religious persecution still exists, but the Indian constitution recognizes religion as a fundamental right, meaning citizens are free to follow whichever faith they choose. Approximately 1.2 billion people in the world currently practice Hinduism, with 95 percent living in India. Because of this high number, it is easily the most popular religion in the region, with roughly 79.8 percent of India’s total population self-identifying as Hindu.
