1530s, "condition of being smaller," from Middle French minorité (15c.), or directly from Medieval Latin minoritatem (nominative minoritas), from Latin minor (see minor (adj.)). Meaning "state of being under legal age" is from 1540s; that of "smaller number or part" is from 1736. The meaning "group of people separated from the rest of a community by race, religion, language, etc." is from 1919, originally in an Eastern European context.
a culturally, ethnically, or racially distinct group that coexists with but is subordinate to a more dominant group. As the term is used in the social sciences, this subordinancy is the chief defining characteristic of a minority group. As such, minority status does not necessarily correlate to population. In some cases one or more so-called minority groups may have a population many times the size of the dominating group, as was the case in South Africa under apartheid (c. 1950-91).
