Common App: Can you omit Racial Identity?

If you do, do they just assume Caucasian?

Yes. But is it listed anywhere else? Your SAT/ACT score report or your transcript?

As to what they will “assume,” who knows? They won’t say.But they may make assumptions based on surname, parents’ place of birth, or a number of other things. They will certainly not assume you are URM, though, IMO
