A total of 66,484 events and projects were recorded for the United States Bicentennial celebration.
The figure comes from the final report of the American Revolution Bicentennial Administration. It counts activities held between March 1975 and December 31, 1976, covering the official anniversary period rather than only events on July 4.
The total included 27,489 projects and 38,995 events. The administration also counted activities held outside the United States, showing that the Bicentennial was not limited to celebrations within American territory.
The scale of the number reflects the decentralized structure of the Bicentennial. Rather than concentrating the observance in one exposition or one city, organizers encouraged local communities, institutions, and organizations to create their own programs. America250 similarly promotes participation through state and territory commissions, educational projects, service initiatives, and community celebrations.
