Positive steps to enhance the diversity of some group, often to remedy the cumulative effect of subtle as well as gross expressions of prejudice. When numerical goals are set, they are set according to the group's representation in the applicant pool rather than the group's representation in the general population. For example, a medical school with an affirmative action program would seek to admit members of an underrepresented group in proportion to their representation in the population of those who had completed pre-medical requirements and wished to attend medical school. Affirmative action should be distinguished from reparations.
