Judging by the thread it would seem that the need for URM status is a subject that is very difficult to research (joking). First of all, let's define what URM really means. Under Represented Minority means that you come from a racial population that is statistically significant, but lacking in reciprocal physician numbers. Blacks, for instance, comprise 13% of the American population, but only 6% of the total enrollment of medical school students (MD and DO). On the other side of the coin are Over Represented Minorities such as Asians who make up only 4-6% of the population, but 15-20% of med school students.
IF you guys ever make it to this side (med school) you will learn about something called healthcare disparity/inequality. In a nutshell, the populations with the greatest need for healthcare are the URM populations (Blacks, Latinos, Native Americans, Pacific Islanders, etc.). It is a fact that URM students are more likely to treat those in URM populations. It is also a fact that URM students are more likely to research disease processes that primarily affect URM populations. (I point you to the AHRQ factsheet
http://www.ahrq.gov/research/disparit.htm). It is also the hope of most ADCOMS that class diversity will increase the cultural competency of all students (students teaching each other about their cultures), which will increase the likelihood of doctors connecting with patients from a different cultural background.
As a student that works closely with my school's admissions office I can tell you that we actively seek qualified URM candidates because diversifying our medical school classes falls directly in line with our schools mission of supplying quality healthcare to EVERY citizen of our state.
In the admissions process URM status doesn't give you as big of a leg up as many people think it does (If it did we would have a lot more URMs in med school).
For those of you concerned that the majority of URMs in med schools are Black millionaires that gamed the system I have bad news for you. There is another box that everyone can check that denotes economic disadvantage which a lot of schools take more seriously than URM designation (It just so happens to be that a higher percentage of URMs are also economically disadvantaged as well).
Lastly, can we please stop with this low MCAT scapegoat. There is only one section that has had any real relevance to med school and that is the Bio section (usually everyone's highest score).
If you all do make it to this side and see the terrible shape of our healthcare system I hope that it opens your eyes to the need to train more culturally competent and diverse doctors.
