The ethnicity is curious, because it seems like in the US there are a few, very distinct boxes, where people seems to be extremely concern to belong (in general, of course). Being "in the middle" seems confusing. In other parts of the world (I am thinking South America in particular), where you can have similar mix of ethnic background, society seems to care less about "boxes" and the boundaries are way more relaxed. People seems not to be that interested in being classified into a distinct box and care less about it.
