Counting methods

In 1995, the National Park Service estimated that 400,000 people attended the Million Man March in Washington, D.C., the official count for the event.^[56] The organizers said that more than a million people turned out, and they threatened to sue the Park Service unless it revised its estimate. Congress, in response, barred the agency from producing any more crowd estimates.^[57]

Since then, official crowd estimates for organized political protests, demonstrations, and marches have relied on an amalgam of police data, organizer estimates, the research of crowd scientists, and journalists.^[58]
