In social science, agency is the capacity of individuals to act independently and to make their own free choices. By contrast, structure is those factors of influence (such as social class, religion, gender, ethnicity, ability, customs, etc.) that determine or limit an agent and their decisions. The relative difference in influences from structure and agency is debated—it is unclear to what extent a person's actions are constrained by social systems.
