What is a family composed of two parents and their children known as?

An extended family includes additional relatives beyond the immediate parents and children, such as grandparents, aunts, uncles, and cousins. This structure emphasizes a broader familial network and support system, which is not confined to just two parents and their children.

A family of choice refers to individuals who choose to create strong, familial-like bonds with people who are not related by blood or marriage. This concept often includes friends or community members who provide emotional and social support, differing from the traditional nuclear family structure.

A blended family forms when two separate families unite, often due to remarriage, including step-parents and step-siblings. While this structure includes children, it does not fit the definition of a nuclear family, as it arises from the merging of different family units rather than being composed solely of two parents and their biological children.
