Stratification refers to the hierarchical organization of individuals into different social groups based on factors such as income, education, occupation, and social status. This research area examines how these different factors interact to create and perpetuate inequalities within society. Researchers in this field analyze how social stratification impacts individuals' opportunities, life chances, and overall well-being, as well as how it contributes to the reproduction of social inequalities across generations. By studying stratification, researchers aim to understand the mechanisms through which group-based inequalities are created, maintained, and potentially disrupted, with the ultimate goal of promoting greater social equality and justice.
