Ethnicity 2007 As a constructed category of human difference, 'ethnicity' has given way to 'culture' in its shared genealogy in the new millennium. Public knowledge about such phenomena as 'ethnic cleansing', debates on immigration, and the use of ethnicity as both a dependent and independent variable in research and policy are central realities in the domestic and foreign policies of many nations. The social psychology of group affiliation, nationalism, and the use of ethnicity (as well as gender) in workplace diversity, or the deployment of ethnicity in electoral politics continues to perplex and complicate human social interaction.
