Family types can vary widely, but they generally fall into a few main categories. A nuclear family consists of two parents and their children living together. In contrast, an extended family includes additional relatives, such as grandparents, aunts, uncles, and cousins, often living nearby or in the same household. Another common type is a single-parent family, where one parent raises their children alone. Additionally, blended families form when one or both parents have children from previous relationships, creating a new family unit. Each family type has its unique dynamics and challenges, reflecting diverse social structures.
