What family structure is defined as one man and one woman with their children?

The family structure that is defined as one man and one woman with their children is known as a nuclear family. This type of family typically comprises two parents and their biological or adopted children living together in a single household. The nuclear family is often characterized by its smaller size and the focus on the primary relationship between the parents alongside that of the parents with their children.

This structure is contrasted with other types of family arrangements. For example, an extended family includes additional relatives, such as grandparents, aunts, uncles, and cousins, all living together or maintaining close relationships. A single-parent family consists of only one parent raising one or more children, while a blended family involves two parents who have children from previous relationships or marriages coming together to form a new family unit.

The nuclear family is often considered the traditional family structure in many cultures, and this model is significant in various social and economic contexts, shaping parenting styles, household dynamics, and family responsibilities.
