Religions, caste, and class are the three main social phenomena in India. The caste system is based on varna and jati divisions and is characterized by its innate and hierarchical nature where one's caste determines status and occupation. Caste restricts food and marriage practices and maintains social control. Recent trends show changes in education, jobs, food, and marriage customs are challenging the caste system. In India, classes are divided into upper, middle, and lower in both rural areas defined by land ownership and in urban areas by occupations like capitalists, professionals, traders, and workers.
