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.
