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.

Discrimination is the process of making unfair or prejudicial distinctions between people based on the groups, classes, or other categories to which they belong or are perceived to belong, such as race, gender, age, religion, physical attractiveness or sexual orientation. Discrimination typically leads to groups being unfairly treated on the basis of perceived statuses based on ethnic, racial, gender or religious categories. It involves depriving members of one group of opportunities or privileges that are available to members of another group.
