The Greater New York Dental Meeting is the largest medical gathering in the US, probably the world.
From a league table prepared annually by The Healthcare Convention & Exhibitors Association (HCEA), the Greater New York Dental Meeting topped the list with 58,125 reported total attendees, followed closely by the Radiological Society of North America with 58,044 and then FIME, which counted 47,125 registrants. The American Society of Clinical Oncology and the Society for Neuroscience came in fourth and fifth.
In 2010, the average total attendance for the top 50 healthcare meetings was 19,512, representing a 5.1 percent increase over 2009. Similarly, average reported professional attendance was 13,227, a 7.2 percent increase from 2009. The top 50 largest medical meetings are ranked by reported total attendance, which measures all registered participants at a convention, including exhibitors. In the case of a tie, professional attendance is used to further determine the rank.
The next Greater New York Dental Meeting, at the Jacob K. Javits Convention Center in New York, is held 25-30 November 2011.
