We consider it. I can see all the info Hollow Knight listed above too. Obviously some people also write about it in the little other meaningful experiences section as well. Two things we take into account are:
1) Distance traveled - ditto what Hollow Knight said. Someone who had to figure things out on their own, went to a crappy public school throughout their childhood, work at McDonald's to support themselves through college, etc. will get a little more slack on grades, hours for experiences, etc. There is still obviously a minimum needed - we're not going to accept someone with no clinical experience or an MCAT not consistent with success in medical school. But a kid with no connections who still managed to get 40 hours of shadowing is going to impress me more than a kid with physician parents who got 400.
2) Might help to get an interview/acceptance if you are borderline - Similar to other URM backgrounds (be that racial/ethnic group, rural/underserved area, LGBT, etc.) as well as in state/local students at my school. This is especially true if there is a history of service to low income/underserved communities and essays demonstrate a good understanding of the challenges those communities face in accessing healthcare. This will NOT overcome significant deficiencies in the application, but all else being equal, depending on the makeup of the class so far and the mission/priorities of the school, may move someone up a step on the metaphorical staircase.
