Minority group
Sociological

Louis Wirth defined a minority group as "a group of people who, because of their physical or cultural characteristics, are singled out from the others in the society in which they live for differential and unequal treatment, and who therefore regard themselves as objects of collective discrimination". The definition includes both objective and subjective criteria: membership of a minority group is objectively ascribed by society, based on an individual's physical or behavioral characteristics; it is also subjectively applied by its members, who may use their status as the basis of group identity or solidarity. Thus, minority group status is categorical: an individual who exhibits the physical or behavioral characteristics of a given minority group is accorded the status of that group and is subject to the same treatment as other members of that group.

Joe Feagin, states that a minority group has five characteristics: (1) suffering discrimination and subordination, (2) physical and/or cultural traits that set them apart, and which are disapproved by the dominant group, (3) a shared sense of collective identity and common burdens, (4) socially shared rules about who belongs and who does not determine minority status, and (5) tendency to marry within the group.
