I think URMs should be:
1. African-Americans duh we all came from Africa, but some of us didn't have a choice in emigrating however many hundreds of years ago.
2. Native Americans and indigenous aboriginal foreigners (I thinking from Canada & Australia)
3. Hispanics and Latinos - even the undocumented ones
4. Emancipated minors/wards of the state/foster children - basically anyone who really had a sucky childhood but somehow managed to make it to the application process
5. Asian-Americans who had to take care of their families. Like second generation...or third generation...Some Asians are traditionally more well-off than others...it's sad that Asians are all lumped in. There are a LOT of different countries....
6. Poor people of all races who are proven and investigated not to be scamming the system
7. Orphaned adults without trust funds or families.
8. Nontrads with families and really really menial crappy jobs. Like men with 12 kids and a stay-at-home wife because of religious reasons...who unlike the Duggars can't bankroll their family. Also single mothers.
9. Men freed from Death Row through the innocence project - and other incarcerated citizens (like why don't we lock up heroin addicts? no, they get rehab, but weed smokers get jail, hmmm)
10. LGBTQII
11. Formerly sexually trafficked women, intimate partner violence survivors, and childhood runaway survivors and anyone who grew up in or escaped a cult.
That's all I can think of right now...but alas, I don't yet rule the world nor do I have any say in the med school admissions process. But that would make for more diverse physician workforce if they got the miraculous URM boost for having lower MCATs/GPAs.
