Final answer:
A group of individuals sharing norms, values, and interdependent behaviors is known as a group. The concept of family fits into this category but is broader, as it includes socially recognized units that form both an emotional and an economic bond, regardless of legal definitions or household arrangements.
Step-by-step explanation:
Two or more individuals who share a set of norms, values, or beliefs and have certain implicitly or explicitly defined relationships to one another such that their behaviors are interdependent is known as a group. This concept aligns with the study of family sociology where a family is considered a type of group.
The U.S. Census Bureau defines a family more strictly as "a group of two people or more (one of whom is the householder) related by birth, marriage, or adoption and residing together." However, sociologists argue that the concept of a family is more diverse, considering any socially recognized groups of individuals who may be joined by blood, marriage, or adoption and who form an emotional connection and an economic unit of society.
