This chapter discusses key concepts related to social interaction and social structure. It defines social interaction as how people relate to and form social bonds with one another. Social structure refers to the framework of predictable relationships in a society, including status, role, groups, and institutions. Status is a social position while role refers to the behaviors expected of a status. Role conflict can occur when roles attached to different statuses conflict. Groups are formed around shared norms and values and involve regular interaction among members. Social structure holds society together through mechanical solidarity based on shared views or organic solidarity based on interdependence of specialized roles.
