Intersectionality is a sociological analytical framework for understanding how groups' and individuals' social and political identities result in unique combinations of discrimination and privilege. Examples of these factors include gender, caste, sex, race, ethnicity, class, sexuality, religion, disability, height, age, weight and physical appearance. These intersecting and overlapping social identities may be both empowering and oppressing. However, little good-quality quantitative research has been done to support or undermine the practical uses of intersectionality.
