In 2014 20,300 students accepted in U.S. medical schools.
In 2003 there were 16,500 students entering U.S. medical schools.
AAMC refused for years to allow the building of new medical schools to compensate for the physician need.
Foreign doctors have filled physician jobs in places where there have been extreme shortages, like The Villages was several years ago. Please don't misinterpret this tho, many foreign doctors give excellent care.
