Crowd in D.C. estimated at 200,000

More than 200,000 people attended the March for Our Lives demonstration in Washington D.C. on Saturday, according to Digital Design & Imaging Service Inc (DDIS). The Virginia-based firm uses a proprietary method for calculating crowd size using aerial photos.

The peak crowd size was 202,796 people, with a margin of error of 15 percent, the firm said. The crowd reached its largest size at 1 p.m., according to the company’s estimates.

The organizers put the total number of attendees at closer to 800,000. The largest single-day demonstration in U.S. history was the 2017 Women’s March, with a crowd size of 440,000 people, according to DDIS’ estimates.

In addition to the massive march in Washington, an estimated 800 other marches were held across the country, including one in Parkland, Florida, where the movement was born following the shooting at Stoneman Douglas High School in February.
