I want to make it clear in advance that the only thing I’ll really prove with this post is that I am clearly not working on a project or contract today.
OK, so, the Glenn Beck’s “Restoring Honor” rally has drawn more controversy for its disputed attendance size than for its content or context. This man can’t seem to brush his teeth without someone scrutinizing his choice of toothbrush.
Estimates have been all over the board, with CBS News on one end assessing the attendance at 78,000 to 96,000 (based on aerial photography taken during the event) and Beck himself estimating the crowd at at least 500,000, presumably based on information gathered from his own camp and attending colleagues (however we cannot eliminate an upcoming claim of divine intervention).
Thankfully, for once we can analyze something Glenn Beck says or does with math and science rather than rhetoric. Using photos of the event, Google Maps’ satellite view, Photoshop and a little math, I’ve come up with my own assessment of the attendance of Beck’s rally.

I started with a large space that has a well-recorded capacity: Penn State’s Beaver Stadium. Beaver Stadium is the second largest stadium in the Western Hemisphere, and fourth largest in the world. Its official capacity is 107,282 people, but the highest attendance ever recorded at a Penn State game held at the stadium was 110,753. Given that Beaver Stadium is slightly tiered, I’ve chosen to use the official capacity as a comparison. Why does that matter? Keep reading…
Next, I went to Google Maps and brought up satellite views of both the Washington Mall and Beaver Stadium, and adjusted their views to correct corresponding altitudes. Both of Google’s measurement guides were adjusted to 500 ft., giving me two corresponding maps at equal aspects. I was then able to crop the stadium and plunk it right into the Potomac to get a sense of scale.
I then found a Beaver Stadium seating chart, which I laid over the satellite image of the stadium to represent where people are actually located when filling the stadium. The area that Nittany Lions fans occupy to fill the stadium to 107,282 was highlighted in red.
Here’s where it gets a little complicated for those who aren’t savvy to graphics design, so I’ll start with a brief explanation. Skip the following paragraph if you already understand pixels…
Pixels are tiny dots of a particular color that form the images on your computer and HDTV. Every photo, website and video you’ve ever viewed on your computer is made of them. They run both horizontally and vertically, and can be measured. So, If your computer monitor has a resolution of 1,920 X 1,080, you have 1,920 pixels running horizontally and 1,080 pixels running vertically across and up your monitor screen. Multiply them, and you will realize that your monitor is displaying 2,073,600 pixels at any given moment. Now back to crowd the analysis…
I took the populated area in red and counted the pixels. All 11,296 of them. Well, my computer helped. A little math told me that 107,282 people divided by 11,296 pixels means that 1 pixel represents 9.487 people at Beaver Stadium at its maximum capacity on my scaled map of the Washington Mall. So, we have a constant. Woot. Let’s continue.

Alright… next I started looking at aerial pictures from the rally to determine the space that the crowd occupied on the Mall, and then filled the areas with red squares to represent those areas as being as crowded as a full capacity crowd at Beaver Stadium. I then counted all of the pixels occupying those squares and got a grand total of 45,957 pixels. Using the people per pixels constant I found earlier, I multiplied 45,957 by 9.487 to arrive at a grand total of 435,994 people.
Please keep in mind that 435,994 represents the amount of people who would have been at the Washington Mall crowd if it had been as crowded as a full football stadium. Based upon the aerial photographs, it clearly was not. 435,994 best represents the maximum amount of people who could have possibly occupied the space represented by the aerial photographs if it were as crowded as Beaver Stadium when filled to capacity.
At the next step, I had to reduce the crowd based upon the sparseness of some areas indicated by the pictures. The North side of the Reflecting Pool is extremely full, so I gave it 100% capacity- meaning that I determined it just as crowded as a college stadium at maximum capacity. In other areas, such as the South side of the Pool, there were sections clearly devoid of people, as well as crowded sections and sections that are more dispersed. I determined the South side of the Reflecting Pool at 75% as crowded as the maximum capacity of a full Beaver Stadium. I continued to state the fullness of the crowd in certain areas as percentages.
Afterward, I recounted the pixels in each individual area, and then multiplied them by their percentage to achieve a more accurate number based upon the crowd photos. When reduced to account for areas of sparsity, I arrived at 32,438.15 pixels. Multiply that by 9.487 people per pixel, and you get 307,740.729 people total (well, 307,741 barring a horrific accident).
So, does that mean that roughly 308,000 people were at the event? Nope. Not at all. There are a TON of problems with my calculations. Among them, Beaver Stadium is built to seat people at elevated angles and in tiers, while the Washington Mall is flat- meaning that if you actually shoved 107,282 people into a flat, non-elevated and non-tiered space the same size as the seating area of Beaver Stadium, they would likely be crammed so tightly that suffocation would ensue. That apparently wasn’t the situation at the North side of the Reflecting Pool last Saturday.
So, I’m being EXTREMELY generous with my numbers here.
If I’m throwing my opinion into the speculation, I’d estimate that around 175,000 people were either attending or milling around the event. I happen to know D.C. residents who strolled over to the Mall to check it out, and left within a half hour. Were they in the photographed crowd? Maybe, but they probably shouldn’t be counted as “attendees.”
I guess the point of this excercise wasn’t so much as to try to figure out the exact attendance, but rather to give a better perspective on the speculation. Beck’s estimate of 500,000+ is pretty unlikely, and CBS News’ number is probably closer, but shoots under the real mark.
It doesn’t really matter how many people showed up, but it does matter that guys like Glenn Beck argue attendance numbers that can’t possibly be verified in an effort to gain clout for an agenda, be it political or otherwise. It’s a Maltese Falcon- a case where the thing itself isn’t valuable, but how it’s used fills volumes.

This one actually never got to me- my girlfriend told me about it and I thought it was just too goo not to include. Legend goes like this: Mikey, the finicky kid made famous by enjoying a breakfast cereal that everyone thought was delicious (I liked Vienna sausages and I couldn’t even get on the morning announcements) apparently also enjoyed the closest thing an 80s kid could get to crack cocaine…. Pop Rocks. In addition, rumor was that he liked to dabble in another illicit kid drug from that era: copious amounts of cola. Combined, it was a highball of doom… literally an explosive cocktail that could and supposedly did take lives. One Little Mikey’s in particular.
Given that I didn’t actually hear this one as a kid, I went right to the research. The whole thing was devised by the superlative “they” that now make less-reliable cars, uncomfortable airline seats and crappy television. First, they observed the gaseous nature of both Pop Rocks and Pepsi. Then, they imagined the effect of these two substances combined in a human gastrointestinal system. Afterwards, they placed the whole thing into a narrative in which some sugar-crazed or culinarily ambitious child met his demise. Why did they choose Mikey? My guess is that famous kids didn’t grow on Disney trees back then, and Mikey was as good as they could have done to punctuate the shebang with a little celebrity intrigue.
Turns out, they were about 63% right on this one. There was a Super Mario Bros. 2 that was released in Japan long before our familiar U.S. version that was essentially a much more difficult version of the first game. In fact, it was such a hard (not to mention unoriginal) game that NES decided to redevelop the game for the U.S. They took an odd little Arabian Nights-themed game called
