Which states have the most academic medical centers?
Ohio leads with 18 academic medical centers, followed closely by Pennsylvania and New York, each with 17 AMCs. Ohio, with a population of around 11.7 million, is home to some of the nation’s most prominent AMCs, including Cleveland Clinic Main Campus, Cincinnati Children’s Hospital, and the Ohio State University Wexner Medical Center.
Pennsylvania, which has nearly 13 million residents and two major metropolitan areas—Philadelphia and Pittsburgh—is also rich in leading academic institutions. Its top AMCs include The Hospital of the University of Pennsylvania, UPMC Presbyterian, and Thomas Jefferson University Hospital, all among the largest in the Northeast.
New York, one of the country’s most populous states with nearly 20 million people, boasts renowned medical schools such as Columbia University, Weill Cornell Medicine, and New York University. These institutions are affiliated with some of the largest AMCs in the nation, including Presbyterian Weill Cornell Medical Center, Tisch Hospital, and Presbyterian Columbia University Irving Medical Center.
Which states have the fewest academic medical centers?
Eight U.S. states currently have no academic medical centers. These states are Montana, Wyoming, Delaware, Alaska, Nevada, Idaho, Hawaii, and South Dakota.
How are academic medical centers different from teaching hospitals?
In most cases, an academic medical center is also a teaching hospital, but not every teaching hospital is an academic medical center.
An AMC is always affiliated with a medical school and confers medical degrees. On the other hand, teaching hospitals provide continuing medical education to medical students, residents, and other healthcare professionals. Teaching hospitals are usually associated with a medical school but do not confer medical degrees themselves.
As of July 2025, the HospitalView product currently tracks 226 hospitals that are classified as AMCs and 1,431 that are considered teaching hospitals. There are 204 hospitals that are considered both.
