<p>newjack, yes, geographical diversity is legit and desirable, as is economic diversity but it is not to be confused with AA. That is, a college can go out and seek lower income students as part of commitment to diversity and part of seeking out under-represented groups but it is not to be called AA. In practice, it turns out the same as AA but the aims of AA are different from the aims of seeking out diverse representation on campus. Hope this helps.</p>
