Introduction to Sociology course

Chapter 8. Groups

To which groups do you belong? How important are groups to you? Sociologists have long recognized that the theme of social relations entails more than the study of networks. The study of social relations also includes examination of group formation and intergroup relations. People belong to groups; they have group affiliations and identities. In this meeting, we will discuss the key sociological theories, concepts and findings on groups.
