Affirmative action (known as reservation in India and Nepal and positive discrimination in the UK; also known in a narrower context as employment equity in Canada and South Africa) is the policy of favoring members of a disadvantaged group who suffer or have suffered from discrimination within a culture. Often, these people are disadvantaged for historical reasons, such as oppression or slavery. Historically and internationally, support for affirmative action has sought to achieve goals such as bridging inequalities in employment and pay, increasing access to education, promoting diversity, and redressing apparent past wrongs, harms, or hindrances. The nature of affirmative action policies varies from region to region. Some countries, such as India, use a quota system, whereby a certain percentage of government jobs, political positions, and school vacancies must be reserved for members of a certain group. In some other regions where quotas are not used, minority group members are given preference or special consideration in selection processes.
In 1989, the International Convention on the Elimination of All Forms of Racial Discrimination stipulated (in Article 2.2) that affirmative action programs may be required of countries that ratified the convention, in order to rectify systematic discrimination. It also states that such programs "shall in no case entail as a consequence the maintenance of unequal or separate rights for different racial groups after the objectives for which they were taken have been achieved."
Several countries, such as India, reserve political, vocational and educational positions for members of disadvantaged groups. In India, this varies between 30% (nationwide) and up to 70% (in Tamil Nadu). In the United States, affirmative action in employment and education has been the subject of legal and political controversy, and in 2003, a pair of US Supreme Court decisions (Grutter v. Bollinger and Gratz v. Bollinger) permitted educational institutions to consider race as a factor when admitting students while prohibiting the use of quotas. In other countries, such as the UK, affirmative action is rendered illegal because it does not treat all races equally. This approach to equal treatment is described as being "color blind." In such countries, the focus tends to be on ensuring equal opportunity and, for example, targeted advertising campaigns to encourage ethnic minority candidates to join the police force. This is sometimes described as "positive action."
