Systemic Racism (also called structural or institutional racism) - racism that exists across a society within, and  between institutions/organizations across society

• Refers to the complex interactions of large scale societal systems, practices, ideologies, and programs that produce and and perpetuate inequities for racial minorities. The key aspect of structural or systematic racism is that these macro-level mechanisms operate independent of the intentions and actions of individuals, so that even if individual racism is not present, the adverse conditions and inequalities for racial minorities will continue to exist (Gee & Ford, 2011).
• Examples: housing discrimination, government surveillance, social segregation, racial profiling, predatory banking, access to healthcare, hiring/promotion practices, mandatory minimum sentences
