Affirmative action in the United States is a set of laws, policies, guidelines, and administrative practices "intended to end and correct the effects of a specific form of discrimination"[1] that include government-mandated, government-approved, and voluntary private programs. The programs tend to focus on access to education and employment, granting special consideration to historically excluded groups, specifically racial minorities or women.[1][2] The impetus toward affirmative action is redressing the disadvantages[3][4][5][6][7] associated with past and present discrimination.[8] Further impetus is a desire to ensure public institutions, such as universities, hospitals, and police forces, are more representative of the populations they serve.[9]
