Sociologist Louis Wirth (1945) defined a minority group as “any 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 term minority connotes discrimination, and in its sociological use, the term subordinate group can be used interchangeably with the term minority, while the term dominant group is often substituted for the group that’s in the majority. These definitions correlate to the concept that the dominant group is that which holds the most power in a given society, while subordinate groups are those who lack power compared to the dominant group.
