The sociology of race and ethnic relations is the study of social, political, and economic relations between races and ethnicities at all levels of society. This area encompasses the study of systemic racism, like residential segregation and other complex social processes between different racial and ethnic groups, as well as theories that encompass these social processes
The sociological analysis of race and ethnicity frequently interacts with postcolonial theory and other areas of sociology such as stratification and social psychology. At the level of political policy, ethnic relations is discussed in terms of either assimilationism or multiculturalism. Anti-racism forms another style of policy, particularly popular in the 1960s and 1970s. At the level of academic inquiry, ethnic relations is discussed either by the experiences of individual racial-ethnic groups or else by overarching theoretical issues.
