The concept of family is defined as a socially recognized group that provides care, education, and economic support to its members. Families typically consist of individuals connected through marriage, blood relations, or adoption. This universal institution exists across all societies and cultures worldwide, highlighting its fundamental role in human social organization.
Marriage serves as a foundational element of family, representing a legal partnership between individuals. It often encompasses aspects such as sexual relations, child-rearing responsibilities, and financial cooperation, establishing the basis for family structure and function.
Sociologists categorize families into several types based on their composition and living arrangements. The nuclear family consists of one or two parents and their children living together under one roof. This family type is prevalent in high-income, highly industrialized nations. In contrast, the extended family includes the nuclear family plus additional relatives such as grandparents, aunts, uncles, or cousins, all residing together. Extended families are more common in low-income, less industrialized societies.
Another important family form is the family of affinity, which comprises individuals who consider themselves family despite lacking blood relations or legal ties. These families are more frequently found in affluent, industrialized countries, reflecting evolving social dynamics and definitions of kinship.
