Aerial photos used to estimate crowds at demonstrations
February 21, 2003 7:25 AM   Subscribe

So just how many protesters WERE there at the anti-war demonstration? Throughout history organizers give a higher turnout estimate and police give a lower one. The San Francisco Chronicle hired an independent third party to take aerial photos and estimate the number of demonstrators last Sunday, and the results show a crowd count much lower than what either the organizers OR the police had estimated. In Washington, DC, as USA Today notes, the Park Service "counted crowds for decades until 1995, when Nation of Islam leader Louis Farrakhan threatened to sue after Park Police estimated attendance at the Million Man March at 400,000." Is having an accurate count a good thing? Will anyone care?

From oissubke's link:

the protests attracted about as many people this weekend as the movie "Kangaroo Jack."

ouch.

Should we really have a president who makes decisions based on a congregation of folks with a certain agenda who get out and carry signs and make a bunch of noise?

Rallies are relatively easy to put together. It's a public relations push in an attempt to promote one agenda over another. I don't know about you, but I'd rather not have a presidential administration flip-flop on national policy due to political push that (to piggyback off ednopantz's comment) got about the same turnout as the movie Kangaroo Jack.

That wouldn't make any more sense than the president declaring that, due to massive public support of kangaroos, they administration would now....

If the President announced a war on kangaroos, I wonder what percentage of the public would believe that at least one of the September 11th hijackers was a marsupial.

What a bunch of useless losers! Right, Ken?

People who attend protests and rallies aren't necessarily losers. They're trying to promote their political agenda, which is a great and noble thing. That's what keeps politics moving in this country.

But it's a mistake to look at what's essentially a political public relations event and regard it as "the will of the people."

It's the will of some people. If they can promote their agenda so that other people agree with it, that's great. If not, oh well. But it doesn't make sense to think that a presidential administration should change their policies, views, and opinions because of some successfully organizers.

Or, to put it another way, would you expect Gore to suddenly encourage a ban on abortion just because a quarter-million conservatives got together and rallied for it?

I get your reasoning to a point, ossibuke, but I don't see how your argument is strengthened by basing it on an essay playing a numbers game that has no relevance. The industry doesn't even compare TV to box office numbers, much less protest to box office numbers.

I attended the San Francisco march, and I don't think I met anyone who thought Bush's mind could or would be changed by any of the protests over the weekend; yet I met a lot of people who didn't just stay home say "why bother?" for that reason. I didn't meet anyone particularly concerned with the numbers of people marching; everywhere we went, we were surrounded by people as far as we could see, and that was good enough for us. To be there was to be part of a voice against the war. At the same time some people feel safer duct-taping their windows and learning to don gas masks, some of us feel less powerless by creating a forum to be heard en masse, particularly when it is a voice that's not getting much play in the pro-war (yet ostensibly liberal) press these days.

The protests over the weekend were large; whatever the counting method, by comparison to other such demonstrations in the past, they were large. It demonstrates that a certain number of people are willing to go out of their way at a very particular time to protest. At the very least, they might inspire people to think a little more closely about their level of support for the war. That's Bush's concern anyway, particularly in an environment where his administration is in the position of trying to talk people into a war rather than responding to our call for war. He won't change his mind (because, after all, it's all about him, not us), but we're not going to make it pleasant for him.

If a comparison is necessary, it might be a little more honest to compare the numbers of anti-war demonstrators to those of pro-war demonstrators. After all, there's a big difference between the level of support of people sitting on their asses accepting the war because TV and radio tell them to and those who would get up and take action, no matter which side they're on. (What I find interesting on another level is how supporters of the war are in favor of extending democracy into the Middle East, yet are not only critical of expressions of democracy at home, but also tell us that it's of no use anyway.)

As for the original post, if they are coming up with ways to count crowds that is more efficient, and they are forthcoming about the method's flaws, then good for them. We could avoid the argument over numbers, which both sides of a debate tend to inflate, and we possibly could get past the apparent inability to interpret such numbers in a logical context.

From the article: This is the first time the firm has used its equipment for crowd estimation

That's an interesting statement, buried halfway down the article.

The 1963 march is not memorable for the size of the crowd that was there, but for the eloquence of Dr. King's speech. If there had been half as many people there, it would not have been less important.

Individuals may argue over moral positions, but political leaders pursue policies based on advancing their interests, as they see them.

The civil right campaign was ultimately successful not because of it's 'rightness' or morality, but because a majority of lawmakers saw that it was in their interest to pass decent civil rights laws.

What do you think would have happened in 1963 if, instead of Dr. King making an "I have a Dream" speech, there had only been signs saying that President Kennedy was worse than the KKK, and that it was all about oooooil?

What specifically, are the credentials of the "Santa Clara air photography firm Air Flight Service" (a company with 20 years of experience in taking photographs for topographical maps for government agencies and private companies.) for counting crowds? They are photographers, not mathematicinas or statisticians. And SFGate, well.......

"I'm surprised that SFGate didn't hire Dr. Farouk EL-Baz, director of the Center for Remote Sensing at Boston University. El Baz has developed mathematical models for counting trees and sand dunes.

"Last week, Dr. Michael Guillen, science editor of ABC's "Good Morning America" program, asked Dr. El-Baz if the Center could conduct an analysis of some 35mm photographs obtained by the television network from the Park Service. Dr. El-Baz gathered a team of 10 research associates and graduate students of the Center in order to develop a methodology for applying remote sensing techniques to the problem of crowd size estimation. After working overnight, the team on Thursday morning, October 19, produced a n estimate of 870,000 people in attendance at aboiut 3:30 p.m., with a margin of error of about 25 percent, which meant the actual size of the crowd at that time could have been as low as 650,000 or as high as 1.1 million."

The Park Service tried to hire El Baz to count crowds at DC protests (according to NPR), but Congress refused to fund this.

Don't fall for it.

Say, for example, I'm against the protests. The simplest way for me to deflect attention away from the goal of the protest is to question the number of people (popularity) that attended the protest.

Once I do that, protest supporters fall for the bait and spend their time arguing with me about crowd estimation and media bias and other spurious topics. Their real message is now being confused and hidden behind a battle over numbers.

This happens with every large protest and people continue to fall for it. This is not to say don't defend the true number of people who attended, just don't let that fight overtake the real goal of your protest.

Trouble being that many people who favor a war with Saddam, including myself, consider it unseemly to demonstrate in favor of bloodshed.

The attitude isn't enthusiasm for war, but rather conscious resignation to the position that war is the best of a bad lot of options.

Hardly "accepting what TV gives" us. I would also note, that if one reads elite newspapers, NY Times, Wapo, there is no shortage of antiwar commentary, analysis, and news.

For the anti-war camp, the trouble isn't that people are blindly accepting war. The trouble is they have thought about war and are in favor of war, albeit by smallish but significant margins.

The Kangaroo Jack observation applies to the American marches, which were anemic compared to the rest of the world. A couple hundred thousand in Australia, a million in London, another million in Rome, another couple million in scattered cities across Europe -- I guarantee you that worldwide, more people rallied than watched a CGI kangaroo.

Though, if Kangaroo Jack had beaten the marches worldwide, I'd suggest we have a far, far larger problem at hand then a simple war in the Middle East.

I don't base my argument on that. I posted the link because I thought it was amusing. My later comments were intended to stand on their own.

Political rallies are public relations events. You know this. I know this. That's why they have organizers and press releases and so forth. It's not like they're spontaneous gatherings of offended citizens (though some may participate on a whim.) This applies to both liberal and conservative rallies and protests.

If they can steer public opinion in a direction that they think is beneficial, then good for them. But it's irrational to see pictures of a relatively small number of people (corporations and celebrities can, and do, easily stir up more people than these protests did), and leap to the conclusions that "the public" is against the war, and that Bush is ignoring the fact that "the people have spoken".

If you're so convinced it is the right thing to do (and that ultimately it will avoid more bloodshed), why not? It sounds like you've found a wonderfully passive way to absolve yourself of responsibility for bloodshed. If you support the war with words, why not with actions?

Also, parallel to your argument, most protesters aren't against doing something about Saddam, just that war is the worst of a bad lot of options; many feel war should be the last of any lot of options.

Many people support the war because they believe it is right. Many people support the war because they are told to (or, these days, are scared into it). On both sides of the debate, a lot of people take their position based on something other than a personal assessment of available information. I would still say that a person who puts action behind dialogue is a step ahead of someone who would not.

From the linked article: "That number does not take into account marchers who dropped out before or arrived after the moment the photo sequence was shot. Calculating a precise number of protesters for the entire rally is not possible from this survey..."

And from the post: "So just how many protesters WERE there at the anti-war demonstration?"


The linked article clearly states that it cannot answer the question of the post.

I was at the rally, and it was definitely a lot smaller than the last one. But a snapshot of the crowd at 1:45 has very, very little to do with "how many protesters were there."

Also, for all of those who like to compare numbers between the protesters and brain-dead moviegoers, I counted roughly 25-30 pro-war marchers in San Francisco. I guess that means the popular opinion in the Bay Area is about 65,000 to 30, using even the most conservative estimates. So precisely .0461% of people here are for war, and 99.9539% are against war.

Glad I'm in the majority...

Perhaps what I am speaking to is more a contrast between liberal and conservative methodologies. One thing I like about being more liberal is that liberals I have been involved with tend to take personal action on behalf of their beliefs; they get involved. Many don't. Many do a lot more in support of their causes than I do. The conservatives I know (I have many friends who...oh, never mind) are perfectly happy to let other people take those actions for them; their activism is in agreement.

What I note is the degree to which personal conviction translates into personal effort, and that's across the board. I respect the strength of belief of an anti-abortion protester in a march more than I do that of someone who is pro-choice and remains silent. It's easy to sit back and agree; it's not so easy to do something about it.

So it's more like, "I walked in a protest, therefore I've given more than casual thought to my position; what about you?"

Well, first of all, I don't want to hang aroud with the kind of yahoos who attend pro-war rallies. Ever seen one? Weird folks missing key teeth clutching pictures of politicians. Shudder.

Secondly, war isn't the kind of thing you should be enthusiastic about. Demonstrations often function more as pep rallies for the faithful and cheering on violence and destruction is a dangerous attitude to have.

Third, on the cheering on point, it plays into the hands of the anti-war camp who argue that those backers of war are callous or disinterested in the realities of war.

Fourth, "Make war on Saddam because he is a fascist genocidal dictator with a meglomanical belief that acquisition of nuclear weapons will enable him to lead the Arab world out of its 500 year slump, and he does not behave as conventional deterrence theory dictates he should" doesn't fit so well on a sign. Seriously, the case for war is one that requires a couple of sentences to explain it and a familiarity with Saddam, his history, and the historical trajectory of the region over the last 50 years.

Fifth, it won't make the slightest difference anyway.

/sarcasm
Protesting in this way is neccessary because we can, in our society. It helps to remind us all that the people of a country are it's identity. If polititians choose to ignore the ire of a proportion of the population who are willing to show their feelings on a subject by protesting, more fool them. People who have the strength of character to get out and show solidarity with those they feel repressent their opinions better than the hyper-spun government demagogues are probably the same proportion of the population who get out and vote.

Nope, no agenda here, just taking the 'ol fingers for a jog on the keyboard; gotta keep in shape.

I was there and around 1:45 was headed for Naan & Curry, about 4-5 blocks away, for a bite to bring back to the rally. For what it's worth, the side streets were packed with people coming and going, and there was a street a block away filled with an overflow march.

I don't know how that factors into an accurate count, but I know that the count of people on Market street and the plaza at 1:45 isn't the whole story.

Rallies are not designed to change Bush's and/or any given chickenhawk's mind. If minor things like reason and compassion and ethics and morality have no effect on them, it's doubtful that these rallies will.
posted by fold_and_mutilate at 11:37 AM on February 21, 2003


Rallies are designed to be catalysts for change. Recent war-prevention rallies consisted of much more than people carrying signs. Much factual printed information is disseminated, new contacts are made, and many folks man information booths with a number of diverse viewpoints. People's voices are heard, just as they were during civil rights marches, and the marches against the national nightmare/travesty of our involvement in Vietnam.

In my own personal experience, thoughtful people who may be in favor of the war, but who are willing to consider such minor things like reason and compassion and ethics and morality, are in fact persuaded by coming in contact with people at rallies, or events surrounding them. Some are not. But voices are heard, and more and more light is brought to bear on any given issue. Those who disparage or downplay such voices are merely afraid of what that light may bring forth.

Apparently enough that Saddam now feels comfortable ceasing to cooperate with the inspectors, which just makes war more likely. Joe Conason suggests that in order to counter this spin, the next anti-war protests should be at Iraqi embassies.

Getting back to the point of the post - numbers of demonstarters at the SFI antiwar rally, I guess no one on Metafilter can answer my question:

What specifically, are the credentials of the "Santa Clara air photography firm Air Flight Service" in counting crowds? This is "a company with 20 years of experience in taking photographs for topographical maps for government agencies and private companies." - They are ariel photographers, not mathematicians or statisticians. And why is SFGate's estimate, by the same token, more accurate than the police estimates? What methodology did SFGate use to arrive at these numbers?

Maybe these estimates are accurate. But if so, it would be do more to dumb luck, as far as I can tell, than anything. This seems like a political hatchet job to me.

However, there do exist more refined crowd counting methods:

Dr. Farouk EL-Baz, director of the Center for Remote Sensing at Boston University, has developed mathematical models for counting trees and sand dunes which he has adopted for counting crowds. The National Park Service wanted to hire his center to count DC protest crowds but Congress refused to fund the project.

Using ariel photography, the BU Center team estimated the "Million Man March" to be between 650,000 and 1.1 million people - far cry from the 400,000 number widely reported.
