In its contemporary use it refers to colonial and now post-colonial peoples who have been dislocated and scattered to other lands from their countries of origin through the process of voluntary and involuntary migration. It must also be remembered that the migratory process can occur more than once in the same person's lifetime, and that there needs to be a concept of multiple migratory processes and diasporizations. Although it is often erroneously used to refer to Black communities only, all people have ethnicity so that white people are also part of particular ethnic groups. To avoid this confusion, it is best to spell out the relevant ethnic groups explicitly, where this is appropriate depends upon the context. This means a tendency to perceive the world from the point of view of one's own culture.
Ethnocentrism can lead to racism when applied to issues of race.
A rather dated racist term which is to be avoided. It is preferable to talk of a society receiving migrants. However, the term is associated with racism and is also confusing since it also describes people from India. Use native American instead. However, in the British context, it is not a helpful term since it would be difficult to identify the indigenous British in this sense.
