Extended family

An extended family includes relatives beyond parents and their children, such as aunts, uncles, grandparents, and cousins, who live either in the same household or close by. Two specific types are the stem family and the joint family. Sometimes, an extended family forms when a relative, like an elderly parent, moves in with their adult children.

In modern Western cultures, where nuclear families are common, the term is often used loosely to refer to grandparents, aunts, uncles, and cousins, regardless of whether they share a home. But it can also describe a multigenerational household. In some cultures, it means the same as a consanguineous family. The stem family, first described by Frédéric Le Play, involves parents living with one married child and that child’s spouse and children, while other children leave or stay unmarried. This type is sometimes linked to unequal inheritance, as in Japan and Korea, but in places like traditional Romania, northeastern Thailand, or among Mesoamerican indigenous peoples, the child who cares for the parents gets the house while land and property are shared more equally.

Sociologists note that extended families living together can offer advantages like a stronger sense of security and belonging, more support during crises, and additional role models for cultural values. Even when adults move out after marriage, extended family often remains a vital support network. In working-class communities, grown children tend to settle near their parents and other relatives, gathering frequently for events and helping each other emotionally and financially. Despite modern mobility, extended family ties haven’t necessarily broken down; technology like the Internet and social media helps maintain contact. For single-parent households, sharing a home with extended family can ease expenses, though it may also create burdens if only a few members cover most costs. In the United States, about 49 million people (16.1% of the population) live in three-generation households, up from 42 million in 2000, with similar trends in Western Europe. Another 34 percent live within a kilometer of their children.

Around the world, extended families are the basic unit in many cultures, including Asian, Middle Eastern, African, Indigenous (such as Native American and Pacific Islander), Latin American, Caribbean, and even Eastern and Southern European societies. The modern Western nuclear family is not the global norm. In Western Europe, extended families—mostly stem families—were common, with England being an exception. During the Industrial Revolution (roughly 1750 to 1900), more people in Britain and the United States lived in extended families than before or since. Today, children in nuclear families may not meet extended relatives until they are old enough to walk or drive, as middle-class families often move for jobs while branches stay independent. Many families hold reunions, often around holidays, to strengthen connections. In multigenerational households, elders typically lead, especially in patriarchal and patrilineal societies, where the family often includes grandparents, their sons, and those sons’ families. Extended families discuss issues and solve problems together.

In South Asia, the joint family system has long been traditional, especially in India. This arrangement involves many generations living together, bound by common relationships. A patrilineal joint family includes an older man, his wife, his sons and unmarried daughters, and his sons’ wives and children. The oldest male usually heads the family, making economic and social decisions, while his wife often controls domestic matters.
