ethnic means race, right? not nationality, like white europeans are the same as white british, white irish, white americans, white aussies and kiwi's are all white, whatever you call it, aryan. black african black jamaican, black whatever are black, regardless of where they come from.
a person who is all white from 1 country is still the same ethnicity as if they were all white from 10 countries, aren't they? or am i confusing things? not remembering what country your ancestors come from doesn't mean you are not part of that ethnic group and it doesn't make you part of another... and american is not an ethnic background, is it? i dunno.
just trying to be clear on what you mean by 'ethnic background'
