Final answer:
A family is defined in various ways but primarily as a socially recognized group joined by blood, marriage, cohabitation, or adoption, forming an emotional and economic unit. Legal definitions, such as from the U.S. Census Bureau, and beliefs on self-identification as a family also play roles in determining what constitutes a family.
Step-by-step explanation:
What defines a family? The definition of family is complex and varies broadly depending on cultural, legal, and social perspectives. According to the U.S. Census Bureau, a family constitutes "a group of two people or more (one of whom is the householder) related by birth, marriage, or adoption and residing together". However, sociologists assert that the concept of family is more fluid and can be considered as a socially recognized group usually joined by blood, marriage, cohabitation, or adoption that forms an emotional connection and serves as an economic unit of society. Additionally, some individuals believe that family is any group where members consider themselves as such, regardless of legal or biological bonds. This inclusive belief is supported by data showing that 60 percent of U.S. respondents agree that if you consider yourself a family, you are a family.
