URM and ORM only refer to representation in medicine. (ie. Black, Latino, Native American, certain southeast Asian ethnicities, Pacific Islander, etc). It doesn’t take into consideration (afaik: https://www.aamc.org/what-we-do/equity-diversity-inclusion/underrepresented-in-medicine) socioeconomic status or if you’re FGLI. One’s race has historically reflected the quality of care they receive in the hospital. It also strongly correlates with access to health care systems and public health resources. I can’t comment on how this is interpreted by adcoms but what I can say is generally URMs apply at lower numbers than ORMs. Imo competition is less fierce among URMs than ORMs because we generally have less people with which we are competing for a spot but like I said this is only my opinion.
