The following HCEA Top 50 medical meeting list was compiled based on all reported healthcare conventions reported to the Healthcare Convention and Exhibitors Association (HCEA) taking place in 2009 in the United States.
Ranking Criteria
The top 50 largest medical meetings are ranked by total reported attendance, which is all registered participants at a convention, including exhibitors. In the case of a tie, professional attendance is used to further determine the rank. These meetings are reported for 2009 and include both actual and estimated attendance figures. This is self-reported information provided by the event organizers.
HCEA is a not-for-profit organization representing healthcare convention and exhibition organizers and healthcare exhibitors. HCEA has been collecting medical convention and exhibition data for over 50 years and maintains the world’s largest repository of healthcare convention and exhibit data.
