A nuclear family consists of two parents and their children, who live together in a single household and focus on immediate relationships. This smaller family unit, which includes biological or adopted children, is common in urban areas globally. In contrast, a joint or extended family includes multiple generations living together under one roof. This larger family unit can encompass grandparents, parents, children, aunts, uncles, and cousins, with collective household responsibilities and resources. Joint families are prevalent in many parts of the world, where cultural values emphasise family unity, support, and cooperation.
