@ucbalumnus: However, Asian-Americans make up a far greater percentage of the most promising HS applicants (far more than 5%). Until recently (back when the Asian-American population at Dartmouth was around 10% or so), Asian-Americans were still considered URM at Dartmouth.
Though, @intparent, Swat might not be a great example because Asian-Americans are 15% of the student body there now (compare with the 17% at Harvard).
To the OP: Unless you have cultural/ethnic EC’s or plan to write essays/supplements on race (which, BTW, could be a plus at some places) feel free to leave your race out. Probably not a big difference either way.
