definition minority group
Minority group is a term referring to a category of people differentiated from the social majority, i.e. those who hold the majority of positions of social power in a society, and may be defined by law. Rather than a relational  social group , as the term would indicate, minority group refers to the above-described.The differentiation can be based on one or more observable human characteristics, including, but not limited to: ethnicity, race, gender, wealth, health or sexual orientation.ociologist 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..
