The term "minority group" has different meanings, depending on the context. According to common usage, it can be defined simply as a group in society with the lowest number of individuals, or less than half of a population. Usually a minority group is disempowered relative to the majority, and that characteristic lends itself to different applications of the term minority.
In terms of sociology, economics, and politics, a demographic that takes up the smallest fraction of the population is not necessarily labelled the "minority" if it wields dominant power. In the academic context, the terms "minority" and "majority" are used in terms of hierarchical power structures. For example, in South Africa, during Apartheid, white Europeans held virtually all social, economic, and political power over black Africans. For this reason, black Africans are the "minority group", despite the fact that they outnumber white Europeans in South Africa. This is why academics more frequently use the term "minority group" to refer to a category of people who experience relative disadvantage, as compared to members of a dominant social group. To address this ambiguity, Harris Mylonas has proposed the term "non-core group", instead of "minority group", to refer to any aggregation of individuals that is perceived as an unassimilated ethnic group (on a linguistic, religious, physical, or ideological basis) by the ruling political elite of a country" and reserves the term 'minority' only for groups that have been granted minority rights by their state of residence.
