The term was coined by American civil rights advocate Kimberlé Williams Crenshaw to describe overlapping or intersecting social identities and related systems of oppression, domination, or discrimination. Intersectionality is the idea that multiple identities intersect to create a whole that is different from the component identities. These identities that can intersect include gender, race, social class, ethnicity, nationality, sexual orientation, religion, age, mental disability, physical disability, mental illness, and physical illness as well as other forms of identity.[1] These aspects of identity are not "unitary, mutually exclusive entities, but rather...reciprocally constructing phenomena." The theory proposes that individuals think of each element or trait of a person as inextricably linked with all of the other elements in order to fully understand one's identity.
This framework, it is argued, can be used to understand how systemic injustice and social inequality occur on a multidimensional basis. Intersectionality holds that the classical conceptualizations of oppression within society—such as racism, sexism, classism, ableism, homophobia, transphobia, xenophobia and belief-based bigotry—do not act independently of each other. Instead, these forms of oppression interrelate, creating a system of oppression that reflects the "intersection" of multiple forms of discrimination.
