Discrimination is a sociological term referring to the treatment taken toward or against a person of a certain group that is taken in consideration based on class or category. The United Nations explains: "Discriminatory behaviors take many forms, but they all involve some form of exclusion or rejection. Discriminatory laws such as redlining have existed in many countries. In some countries, controversial attempts such as racial quotas have been used to redress negative effects of discrimination.
