Families come in various types, each with unique structures and dynamics. The most common type is the nuclear family, which consists of two parents and their children living together. Other types include extended families, where relatives like grandparents, aunts, and uncles also live together or maintain close relationships, and single-parent families, led by one parent raising their children. Another type is the blended family, formed when one or both partners have children from previous relationships. Additionally, childless families consist of couples without children, while same-sex families include couples of the same gender raising children together. Each family type plays a vital role in society.
