The term 'social class in India' can be summarized by the word 'CASTE'. CASTE is an ancient system of social stratification in India that is based on Hindu religious beliefs. It divides people into distinct social classes, with each class having its own set of duties and privileges. CASTE is a hereditary system, meaning that one's social class is determined by their family's social class. This system has been in place for centuries and continues to shape Indian society today.
