Which family structure involves multiple generations living together?

The choice of extended family structure involves multiple generations living together, which often includes grandparents, parents, children, and sometimes other relatives sharing the same household. This type of structure promotes a strong familial bond and support system, as various generations can provide emotional, financial, and practical assistance to one another. The presence of different age groups can also facilitate the exchange of values and cultural traditions, fostering a sense of community within the family unit.

In contrast, a nuclear family typically consists of two parents and their children, focusing on the immediate family unit without including other relatives. Childless families consist of couples who do not have children, and foster families are those that care for children who are not their biological offspring, often for a temporary period, and do not include generational diversity in the same way that extended families do.
