In most modern extended families, only one married couple per generation lives in the home, although
there are plenty of examples of multiple married couples and their children living together. Young
married couples without children may also continue to live as part of an extended family until they have
their own children and are better able to move out on their own.
No matter who is a member of the extended family, there is often only one head of the household.
Depending on the size of the family and the roles each member plays, that leader may be the oldest, most
senior family member, or the most prominent breadwinner who contributes a significant portion of the
family's finances. Another way to determine the head of the household is by whose home it was initially;
a young couple living in a parent's home will see the older generation as the heads of household, whereas
a grandparent who moves into her son or daughter's home will see her child as the head of the household.
Why Extended Families Exist
The extended family is the basic family unit and is quite common in southern and eastern Europe, Asia,
the Middle East, Africa, the Pacific Islands, and Latin America, but it is less common in western Europe
and North America. The reasons for extended families to be so prominent vary, and some factors are
cultural; for example, it may be considered inappropriate for adult children to leave their parents' home
until they have children of their own. Some families may have several adult children still residing at
home, providing parent-like role models to younger siblings. Other reasons for extended families to thrive
include:
Economics: With more adults living as part of the same family unit, the entire family may be
in a better financial situation with more individuals contributing to living costs. Some family
members may be able to provide care for young children in this arrangement, eliminating child
care costs as well.
Health: When an older family member needs regular care, it is common for that individual to
move in with his children or other relatives. This can be an alternative to nursing home care or
assisted living facilities.
Divorce: After a divorce, the now-divorced parents may return to their parents' homes, often
bringing their children along. This may be a temporary arrangement or could be a long-term
living situation, often depending on finances, career changes, child care, and other factors.
