In India, people learn the essential themes of cultural life within the bosom of a family. In most of the country, the basic units of society are the patrilineal family unit and wider kinship groupings. The most widely desired residential unit is the joint family, ideally consisting of three or four patrilineally related generations, all living under one roof, working, eating, worshiping, and cooperating together in mutually beneficial social and economic activities. Patrilineal joint families include men related through the male line, along with their wives and children. Most young women expect to live with their husband's relatives after marriage, but they retain important bonds with their natal families.
