Social structure is defined as the stable interrelationships and patterns of organization among human beings in a society. It consists of institutions that establish roles and statuses for individuals. A social structure includes a normative system that defines values and behaviors, a position system that assigns roles, and a sanction system that enforces norms. A social structure is dynamic and can change over time as it works to integrate individuals and anticipate future roles through a system of cultural patterns, subgroups, and both formal and informal relationships.
