An extended family is a family that extends beyond the nuclear family, consisting of aunts, uncles, and cousins all living nearby or in the same household. An example is a married couple that lives with either the husband or the wife's parents. The family changes from immediate household to extended household. In some circumstances, the extended family comes to live either with or in place of a member of the immediate family. These families include, in one household, near relatives in addition to an immediate family. An example would be an elderly parent who moves in with his or her children due to old age. This places large demands on the caregivers, particularly on the female relatives who choose to perform these duties for their extended family. In modern Western cultures dominated by immediate family constructs, the term has come to be used generically to refer to grandparents, uncles, aunts, and cousins, whether they live together within the same household or not. However, it may also refer to a family unit in which several generations live together within a single household. In some cultures, the term is used synonymously with consanguineous family.
