Minority: definable category of people who are socially disadvantaged. In the membership of this group there is two components: group lacks of social power and it is definable as being distinct from the majority. Majority: definable category of people who are socially advantaged: not defined by inherent characteristics, eg: white males of european descents. Minority is not based on the number of people in one group but rather the power one holds over another: eg: south african apartheid had fewer white population than blacks but dominated them. Minorities face prejudice and discrimination: stigmatization is based on perceived attributes. Eg: the reason you avoid sikh man could be due to them wearing a turban. With minorities being excluded they develop a strong sense of in-group solidarity. When they say minority group are definable they mean they are recognizably different from the majority: eg: race but race is a socially constructed concept.
