Racial discrimination is any discrimination against any individual on the basis of their skin color, race or ethnic origin. Individuals can discriminate by refusing to do business with, socialize with, or share resources with people of a certain group. Governments can discriminate in a de facto fashion or explicitly in law, for example through policies of racial segregation, disparate enforcement of laws, or disproportionate allocation of resources. Some jurisdictions have anti-discrimination laws which prohibit the government or individuals from discriminating based on race (and sometimes other factors) in various circumstances. Some institutions and laws use affirmative action to attempt to overcome or compensate for the effects of racial discrimination. In some cases, this is simply enhanced recruitment of members of underrepresented groups; in other cases, there are firm racial quotas. Opponents of strong remedies like quotas characterize them as reverse discrimination, where members of a dominant or majority group are discriminated against.
