Iraq Body Count Responds To Lancet Study

Iraq Body Count, the anti-war website which has been tracking civilian casualties in Iraq since the U.S. invasion, has responded to the recently-released Lancet study which is claiming approximately 650,000 civilian casualties in Iraq since the invasion.

Here’s a key excerpt:

On average, a thousand Iraqis have been violently killed every single day in the first half of 2006, with less than a tenth of them being noticed by any public surveillance mechanisms. . . .

If the Lancet extrapolation is sound, this would imply a further 920 violent deaths every day (1000 minus 80) which have been recorded by neither officials nor the media. As these are averages, some days would see many more deaths, and others substantially fewer, but in either case, all of them would remain unnoticed.

If we consider the Lancet’s June 2005 – June 2006 period, whose violent toll it estimates at 330,000, then daily estimates become lower but would still require 768 unrecorded violent deaths for every 67 that are recorded. The IBC database shows that the average number of people killed in any one violent attack is five. Therefore it would require about 150 unreported, average-size, violent assaults per day to account for 768 deaths. . . .

One possible way of explaining such a very large number of small-scale unreported assaults is to suppose that many of these are the result of “secret” killings which have resulted from abduction, execution by gunfire, or beheading. But 42% of the 330,000 Lancet-estimated violent deaths in this final 13-month period are ascribed to “explosives/ordnance”, car bombs, or air strikes, all of which carry a fairly heavy and hardly ’secret’ toll (and will generally create at least 3 times as many wounded). . . .

Lancet estimates 150 people to have died from car bombs alone, on average, every day during June 2005-June 2006. IBC’s database of deadly car bomb incidents shows they kill 7-8 people on average. Lancet’s estimate corresponds to about 20 car bombs per day, all but one or two of which fail to be reported by the media. Yet car bombs fall well within the earlier-mentioned category of incidents which average 6 unique reports on them.

In other words, the Lancet study is crap.  Unless you want to believe that there are 19 or 20 car bombings in Iraq per day that go unreported by the media.

And then there’s this:

In 87% of cases where deaths were reported, the survey team asked to see death certificates, leading to the Lancet authors’ statement that “92% of households had death certificates for deaths they reported”. Assuming, as the authors do, that this is representative of the population as a whole, would imply that officials in Iraq have issued approximately 550,000 death certificates for violent deaths (92% of 601,000). Yet in June 2006, the total figure of post-war violent deaths known to the Iraqi Ministry of Health (MoH), combined with the Baghdad morgue, was approximately 50,000.

Lancet, for the purposes of their study, is assuming that officials in Iraq have issued over half a million death certificates, yet in reality officials in Iraq have only issued death certificates that amount to 1/10th of that number.

One tenth.

If that doesn’t make you question the veracity of this study, I don’t know what will.

In the conclusion of their statement, Iraq Body Count states that in order for the Lancet study to be true the following would also have to be true:

  1. incompetence and/or fraud on a truly massive scale by Iraqi officials in hospitals and ministries, on a local, regional and national level, perfectly coordinated from the moment the occupation began;
  2. bizarre and self-destructive behaviour on the part of all but a small minority of 800,000 injured, mostly non-combatant, Iraqis;
  3. the utter failure of local or external agencies to notice and respond to a decimation of the adult male population in key urban areas;
  4. an abject failure of the media, Iraqi as well as international, to observe that Coalition-caused events of the scale they reported during the three-week invasion in 2003 have been occurring every month for over a year.

So which do we believe?  The Lancet study conclusions or the realities of the list above?

Personally, I subscribe to Occam’s Razor: The simplest explanation is likely the most accurate one.  Which, in this case, means that the Lancet study is probably just plain erroneous.  When you add into that the fact that this Lancet study was released in an October right an election (just like the last Lancet study that wildly overestimated the number of civilian casualties in Iraq), you begin to see that the study is not just erroneous but likely contrived as well to influence politics.

But that probably won’t stop the anti-war left/Democrats (along with their allies in the media) from using it to make their points against the war in Iraq.

These numbers imply 7% of the total male population of Iraq is dead, and an additional 10% of the total male population is wounded by violent means.

Really, this is a pretty absurd claim.  Leave it to WOOF to try and defend it.

If this is false, we need to revist the death counts in Kosovo and Afghanistan. In fact, cluster studies are used to find out mortality rates in most countries that don’t have a stable government. The government is funding, through the Smart Initiative, the teaching of cluster studies. Is that money a complete waste?

I remember when Chomsky argued that the death count from the Khmer Rouge was greatly exaggerated by the Western media. He got death threats. Hopefully no one takes it to that level.

There goes Carrick using numbers again.  That only makes the lefties mad.


What’s going to happen to US industry when the global warming extremists like John McCain double the price of electricity?  I would think all these factories will close and set up in countries where they aren’t scared of technology.

Another interesting tidbit:

Accepting the Lancet estimate would entail concluding that at least 740,000 wounded Iraqis (90% of the total) were not treated or, if treated, not recorded in any way, throughout a 2-year period beginning in mid-2004. It may be that many injured anti-occupation combatants have avoided hospitals to prevent identification or arrest, but they are hardly likely to account for more than a small fraction of this discrepancy. It would further imply that approaching 90% of Lancet’s deaths are also of combatants.

In fact, even if one considers only the victims of car bombs as estimated in Lancet (who are a relatively small subset, and would have no reason to avoid - if they even had the capacity to do so - detection by authorities), then the 220,000 injured which would credibly accompany Lancet’s estimates would far outstrip the 60,000 whom hospitals have recorded treating for injuries from all causes. This would be despite the existence of an ongoing, albeit imperfect, monitoring system specifically designed for such war-related casualty monitoring, one which emergency health service providers should have strong interest in maintaining in order to receive the necessary resources from the Health Ministry.

Nice strawman.

The problem in the Lancet study of course, isn’t the general methodology, but its implementation.  Duh.

You are right about one thing, this calls for a reexamination of anything that the authors have done in the past, prior to the closer scrutiny that their work in Iraq has received.  In particular, the Rwanda numbers need to be revised.

I did not defend any numbers.
I was noting that fraud and incompetence are endemic.
As the recent “correction” of Aug. Bahgdad dead.
500 to 1500.

The numer of dead is an embarrassment to US efforts
after 3.5 yrs.

The military does pay indemnities to accidently killed and injured civilians, but I haven’t heard that number.
Not likely to either.

WOOF on October 16, 2006 at 07:08 am

No doubt there are problems with fraud, WOOF.  And that “correction” by the US military was very strange (extremely poor public relations at best).

The number of dead is more than an embarrassment, it’s a tragedy.  Just as those who would have died at Saddam’s loving hands directly or indirectly would also have been a tragedy.

In either case, it was Saddam and the Ba’athist party, who created this sectarian strife with his oppressive policies towards the Kurds and Shi’ites.  Just as they are guilty of inciting sectarian strife after the end of major combat, and guilty of the murder of 10’s of thousands of Iraqi civilians through directly targeting them.

I’m glad to see you addressing this issue as I’ve been having difficulty finding criticism of the study that doesn’t flow from partisan premises. Care to hazard any guesses as to how the implementation went so wrong?

It was driven completely by partisan politics rather than science.

Easy enough.

The biggest problem IMHO is with the way the data were sampled...they were collected entirely in urban areas, which are regions that tended to be more violent than the national average.

As a result, they came up with violent death rates that likely far exceeded national averages..  The trouble with averages (as opposed to other statistical approaches) is they over-weigh outliers.  If you have the average of the numbers 5, 7, 8, 31, 4, 6, the mean is 11 even though the central tendency (measured by the median) is only 6.5 If you change this to 5,7,8,310,4,6 it even gets worse—the mean is now 57 with the median still 6.5

This would be like using Detroit, Washington DC and other easy-to-get-to big cities to try and work out the violent death rate in the US.  You’d like be off by an order of magnitude.

Also, because there was an obvious bias on the part of the research group in favor of a high number, when the 650,000 number was obtained, there appears to have been no internal self-criticism before releasing the number.  Simple reality checks such as those posed by the IBC people (hardly pro-war themselves, of course) would have called into question their results, and should have forced a more concerted attempt at verifying the accuracy of their results.

Carrick on October 16, 2006 at 09:49 am

Thank you, Carrick! Mike, it is not a “partisan permise” to point out that these researchers did not go to Iraq and actually count graves or document the death certificates they claim to have seen. They claim 547 certified deaths and extrapolate from that 650,000 deaths in less than 4 years. Your a smart guy, do the math. 1,460 days, how many deaths per day? These “researchers” rushed their product in order to publish before Nov 7. Why, again, were they in such a hurry? What scientific principle dictated that results had to be made public before Nov 7, 2006? I am a little fuzzy on that particular scientific principle, would you mind putting us hip to the deal on that one? Have there been a large number of deaths? Yes. The vast majority of them were Muslims, killed by Muslims. Not America.

Quite right although it isn’t a critique of cluster sampling and/or the application of it in the Iraq case either.

Carrick...thank you for your response. One of the findings of the Report reads:

We estimate that as of July, 2006, there have been 654 965 (392 979–942 636) excess Iraqi deaths as a consequence of the war, which corresponds to 2·5% of the population in the study area.

I think that had the authors emphasised the indicated range of possible deaths rather than drawing the reader’s eye to the big single number then there may have been more to talk about. I expressed my surprise and scepticism with the 650K plus figure as well on another thread but when I compare the lower limit of this study with the upper limit of the previous one then the results seem more plausible while still short of convincing. Your’s is the first comment I’ve seen about the urban/rural split or lack of same...could you tell me where you saw this discussed?

2H9...I’m sorry but I missed your comment about Muslims killing Muslims until now. Does that have something to do with the Lancet Report or was that a bonus grump?

MikeAdamson on October 16, 2006 at 02:35 pm

I think, like their previous report, the 95 CL range of 400,000-900,000 is too conservative, because it is purely a statistical statement and does not include any effects of bias in their sampling or in the population distribution used for their multiple cluster study (in their previous study, they made a statistical error, and way under reported the uncertain in their numbers).  The only way (in my opinion) to accurately measure bias effects is by separately sampling each principality, rather than using inaccurate or incomplete census data, as they did.  Unfortunately, this would require probably a 10-20 times increase in the sample size—not a practicable approach until things get much quieter.

In terms of the urban/rural split, are you referring to a difference in violence?  That is easily seen by looking at the clustering of violent attacks in urban areas, even though Iraq, like most 3rd world countries, is much more evenly divided between rural and urban than the United States.

This point is also mentioned in aNON’s link.

While I think that the IBC likely undercounts deaths (especially of foreign nationals and non-Muslims), there are good reasons to think it’s pretty accurate.  Firstly Muslims have a religious obligation to bury their dead quickly, and to have them properly interned. Secondly, it is in their financial interests to get a death certificate (you don’t get a government pension if the death certificate isn’t properly filed). 

I would think the maximum amount the IBC is likely to be off (sans foreign fighters) is a factor of two.  That puts the maximum death toll (militia + army + civilians) at around 100,000 or slightly less.  And by the way, I have no question at all that the previous study was badly flawed.  (If you need a link to the IBC criticism let me know.)

Carrick on October 16, 2006 at 03:09 pm

This survey is directed at America, with the tacit implication that all these innocents are dead because America is killing them. Not the case. Their own co-religionists are killing them, with merry abandon.

No, Mike, they are quite blatant and open about their political agenda. Just read the statements released by them. As for the Lancet, they have an extended history of 5th Columnism and support for socialist/communist regimes.
