FR: More reality based estimates: An Impression Of The Protest: Analysis 1: This gives a range of 240,000 to 320,000 marchers down Pennsylvania Ave, and is based on the time-lapse march route video plus measurements of the route taken from Google Maps. The time-lapse sequence was taken from a webcam over Freedom Plaza at 14th St and E NW, looking ESE down Pennsylvania Avenue toward the Capitol. Analysis 2: This one gives a range of 330,000 to 500,000 demonstrators in front of the Capitol, and is based on the NYT description of the crowd (”A sea of protesters filled the west lawn of the Capitol and spilled onto the National Mall) plus the first photo in the story at the Daily Mail, showing the Capitol West Lawn during the protest, plus measurements taken from Google Maps sat view of the area. How many people were at the big 9/12 "Tea Party" protest?: So, if, for the sake of argument, the Mall to Fourteenth, at [1.18 x 0.5 =] .59 sq. mi., holds 1.2M people, and Penn. Ave. to Fourteenth is [1.25 x 0.2] = .25 sq. mi., then you've got something just over 500K people in that picture. So add that to 80K, and you're up around 600K. Buuuuut, apparently there were people going from the White House to the Capitol “for three hours” according to the caption here. ... So, if the 40-second video is an accurate time-lapse of the 210 minutes from 8:00-11:30, then the 21-36 second march portion actually represents the 78.75 minutes from 9:50:15 to 11:09:00—much less than three hours. Every second represents five and a quarter minutes. If our 500K/30 minutes is right, then there are 87,500 people leaving every second of the video. Which, by the end of the thirty-sixth second means that 1,812,500 people have left. We’re in territory close to the Daily Mail’s number. ... If we treat the USA Today chart as authoritative, this shows well in excess of LBJ’s 1.2 million people. Doing a quick-and-dirty estimate of the amount of ground the crowds around the Washington Monument are occupying gives another couple hundred thousand, putting the total around 1.5 million. ... Now. Here's what happens. If you use the usual method of computing massed crowds (the one the journalists use), you divide the square footage by two... and you get 1,175,035. That's where the 1.2 million number comes from. ... We don't think this crowd is tightly packed, especially if it was walking and converging. We would say the crowd is tighter closest to the Capitol, and fading back to about 9 square feet per person. We boldly suggest there are between 600,000-750,000 people in this picture! March on Washington: How Big Was the Crowd?: There have been a lot of estimates, from the “official” one of 60 to 70 thousand, up to the rumored 2 million. Let’s see if we can make a plausible estimate with some rigor and some idea of possible error. ... In that time, there would be enough people to fill that chunk of Pennsylvania about 8 times. That’s conservative, as what I’ve heard from people actually marching is that it was pretty packed; it wouldn’t be hard to believe the 1.5 million number either. That’s 800,000 people. The Park Service method, filling just the Capitol end of the Mall, is 250,000, but we have many reports of much overflow, and we also can figure that they wouldn’t have marched past for three full hours if there were only that many. The legacy media estimate of 60-70 thousand is ludicrous: we have pictures of twice that. Still, it’s been reported, so we’ll keep it. That’s a pretty wide range. To summarize: Rumored number 2 million “People meter” count 1.5 million Eight “Pennsylvania Avenues” full of people 800 thousand Grant Memorial area by Park Service method 250 thousand Legacy media reports 70 thousand Average all of those and we get 900,000 plus (924,000). Throw out the outliers, we get 850,000. And remember that the 1.5 million was a real count; it’s inherently a more believable number. Our estimate should be “pulled” upward by that. Conclusion: probably well more than 850,000 in the crowd. You can argue the math, and change the assumptions, but no matter how you slice it, the numbers certainly aren't "10's of thousands", but "100's of thousands". Firm
