Aging adults will create the need for an additional 10,000 physicians in that period, while the Affordable Care Act will require about 8,000 more.

The Association of American Medical Colleges (AAMC) has estimated that the United States will be short more than 91,000 doctors by 2020 — 45,000 in primary care and 46,000 in surgery and medical specialties — as more Americans age.
