This is the 35th national study conducted by the American Academy of Family Physicians (AAFP) that reports retrospectively the percentage of graduates from MD-granting and DO-granting medical schools who entered Accreditation Council for Graduate Medical Education (ACGME)-accredited family medicine residency programs as first-year residents. Approximately 8.7% of the 18,929 students graduating from US MD-granting medical schools and 15.5% of the 5,314 students graduating from DO-granting medical schools between July 2014 and June 2015 entered an ACGME family medicine residency in 2015. Together, 10.2% of graduates of MD- and DO-granting schools entered family medicine. Of the 1,640 graduates of the MD-granting medical schools who entered a family medicine residency in 2015, 80% graduated from 70 of the 134 schools (52%). In 2015, DO-granting medical schools graduated 823 into ACGME-accredited family medicine residencies, 80% graduating from 19 of the 32 schools (59%). In aggregate, medical schools west of the Mississippi River represent less than a third of all MD-granting schools but have a rate of students selecting family medicine that is 40% higher than schools located east of the Mississippi. Fifty-one percent (24/47) of states and territories containing medical schools produce 80% of the graduates entering ACGME-accredited family medicine residency programs. A rank order list of MD-granting medical schools was created based on the last 3 years' average percentage of graduates who became family medicine residents, using the 2015 and prior AAFP census data.
