Social privilege is a special, unearned advantage or entitlement, used to one's own benefit or to the detriment of others; often, the groups that benefit from it are unaware of it. These groups can be advantaged based on age, education level, disability, ethnic or racial category, gender, gender identity, sexual orientation, religion, and social class. It is generally considered to be a theoretical concept used in a variety of subjects and often linked to social inequality. Privilege is also linked to social and cultural forms of power. It began as an academic concept, but has since been invoked more widely, outside of academia. This evolution has led to growing awareness and acceptance of this idea in popular culture.
