American Indians and Alaska Natives made the most gains this year after seeing a slight dip in 2011, according to the Association of American Medical Colleges, a nonprofit that represents all 150 accredited medical schools in the U.S. and Canada.

Enrollment for this relatively small population increased by 11.9 percent to 430 aspiring doctors, from last years 379. American Indians and Alaska Natives account for only 0.9 percent of 2012 medical school students and 1.7 percent of the total U.S. population.

David Baines, a physician and member of the Tlingit and Tsimshian tribes, describes the culture shock of moving from his reservation in Alaska to the Mayo Medical School in Rochester, Minn., the Native American Times reported. He credits student and professional organizations, such as the Association of Native American Medical Students, with helping him succeed.

Growing up in an isolated reservation in Alaska, going to medical school was a big shock, especially culturally, he recalls. I was very isolated as the first and only American Indian or Alaska Native student at Mayo Medical School.

The studys figures also shows blacks and Latinos applied to medical school at record-high numbers, 3,824 and 3,701, respectively.

Total enrollment, plus increase, by race and ethnicity (pdf) for 2012:

Overall, more than 45,000 people applied to medical school, a 3.1 percent increase from 2011. First-time applicants also went up by 3.4, signaling an even stronger interest in medicine, according to the nonprofit.

A physician shortage of about 90,000 is expected over the next decade, according to the Association of American Medical Colleges.
