The percentage of US seniors choosing primary care careers remains well below the nation's future workforce needs. Data in this article are collected from the 2012 National Resident Matching Program (NRMP) Main Residency Match and the 2012 American Academy of Family Physicians (AAFP) Medical Education Residency Census, which had a response rate of 100%. The census verified residents who entered training July 2012 from all medical schools. The information provided includes the number of applicants to graduate medical education programs for the 2012--2013 academic year, specialty choice, and trends in specialty selection. Compared with the 2011 Match, family medicine residency programs filled 35 more positions (with 18 more US seniors) through the NRMP in 2012. In other primary care fields, 31 more primary care internal medicine positions (20 more US seniors), two fewer positions in pediatrics-primary care (one less US senior), and 18 fewer positions in internal medicine-pediatrics programs (33 fewer US seniors) filled. The 2012 NRMP results indicate a small increase in medical students choosing primary care careers for the third year in a row; however, students continue to show an overall preference for subspecialty careers.
