Which family structure includes three or more generations living together?

The correct answer is the extended family, which is characterized by three or more generations living together in the same household. This family structure often includes grandparents, parents, and children cohabiting, allowing for a close familial connection and support system that spans across generations.

Extended families can offer various benefits such as shared resources, childcare support, and continued family traditions and values. This structure is particularly common in societies where cultural norms emphasize family cohesion and interdependence.

Nuclear families consist of two parents and their children living independently, which does not meet the definition of including three or more generations. The patrifocal family focuses on a family structure centered around the father or male lineage but does not inherently imply multiple generations living together. A lone parent family consists of one parent raising children, which also does not fit the criteria for a multi-generational household.
