Intersectionality is an analytical framework for understanding how individuals' various social and political identities result in unique combinations of discrimination and privilege. Intersectionality identifies multiple factors of advantage and disadvantage. Examples of these factors include gender, caste, sex, race, ethnicity, class, sexuality, religion, disability, weight, species 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 theory of intersectionality.
