Affirmative action or positive discrimination (known as employment equity in Canada, reservation in India and Nepal, and positive action in the UK) is the policy of favoring members of a disadvantaged group who are perceived to suffer from discrimination within a culture.The nature of positive discrimination policies varies from region to region. Some countries, such as India, use a quota system, whereby a certain percentage of jobs or school vacancies must be set aside for members of a certain group. In some other regions, specific quotas do not exist; instead, members of minorities are given preference in selection processes.
