The United States Bicentennial recorded 66,484 events and projects from March 1975 through December 31, 1976, providing a scale comparison for America250.
The total came from the final report of the American Revolution Bicentennial Administration, the federal body that coordinated the 200th-anniversary observance. Its count included both formal events and community projects held throughout the United States and abroad.
The figure breaks down into 27,489 projects and 38,995 events. The distinction mattered because the Bicentennial was not just a single ceremony: it included exhibitions, performances, educational activities, transportation projects, local celebrations, commemorative objects and many other forms of participation.
A further 654 events and projects were held outside the United States. That international activity helped make the Bicentennial a worldwide observance, while the domestic total showed how extensively communities participated. America250 was created with a similarly national and inclusive ambition, but its programs belong to a different anniversary and should not be added to the 1975–1976 count.
