Discrimination is the act of making unjustified distinctions between people based on the groups, classes, or other categories to which they belong or are perceived to belong.[1] People may be discriminated on the basis of race, gender, age, religion, disability, or sexual orientation, as well as other categories.[2] Discrimination especially occurs when individuals or groups are unfairly treated in a way which is worse than other people are treated, on the basis of their actual or perceived membership in certain groups or social categories.[2][3] It involves restricting members of one group from opportunities or privileges that are available to members of another group.[4]
