The study of social inequality is arguably the most fundamental area of sociological investigation. This research area centers on broad categorical distinctions, such as class, gender, race/ethnicity, and sexuality, and how they emerge, change, and structure opportunities, experiences, and identities. Scholars in the area are currently exploring a diverse array of topics, including crime, health, immigration, religion, and work, utilizing an equally diverse set of theoretical lenses and methodological tools. The Social Inequality area aims to provide students with a broad overview of the field, its development, and current debates.
