Which family structure includes aunts, uncles, and cousins all living nearby or together?

The correct answer is the horizontally extended family. This family structure is characterized by the presence of relatives, such as aunts, uncles, and cousins, living in close proximity or within the same household. This arrangement is distinguished from vertically extended families, which typically include multiple generations living together, such as grandparents, parents, and children.

In a horizontally extended family, the focus is on the lateral connections among relatives of the same generation. This type of family structure can provide social support, shared resources, and a sense of community among siblings and their offspring, reinforcing familial ties beyond the nuclear family setup. Modified extended families, on the other hand, refer to arrangements where extended relatives may not live together but maintain close relationships, possibly through regular contact or visits. The lone parent family structure, as the name implies, consists of a single parent raising children, which does not involve the broader family network described in the correct answer.
