[1][2] Experts distinguish between population-based studies, which extrapolate from random samples of the population, and body counts, which tally reported deaths and likely significantly underestimate casualties.
A nationally representative sample of approximately 2,000 Iraqi adults answered whether any members of their household (living under their roof) were killed due to the Iraq War.
[88] The IBC project, reported that by the end of the major combat phase of the invasion period up to April 30, 2003, 7,419 civilians had been killed, primarily by U.S. air-and-ground forces.
It also lists the primary sources used by the media – mortuaries, medics, Iraqi officials, eyewitnesses, police, relatives, U.S.-coalition, journalists, non-governmental organizations (NGOs), friends/associates and other.
[89] The IBC project has been criticized by some, including scholars, who believe it counts only a small percentage of the number of actual deaths because of its reliance on media sources.
[30][90][91][92][93] The IBC project's director, John Sloboda, has stated, "We've always said our work is an undercount, you can't possibly expect that a media-based analysis will get all the deaths.

ePluribus Media, an independent citizen journalism collective, is tracking and cataloging press-reported possible, probable, or confirmed incidents of post-deployment or combat-zone cases in its PTSD Timeline.
[116] A top U.S. Army psychiatrist, Colonel Charles Hoge, said in March 2008 that nearly 30% of troops on their third deployment suffered from serious mental-health problems, and that one year was not enough time between combat tours.
[155][35] In 2007, an Iraqi Society of Psychiatrists and WHO study found that 70% of 10,000 primary school students in the Sha'ab section of north Baghdad are suffering from trauma-related symptoms.
A study commissioned by the United Nations Development Programme (UNDP), called the Iraq Living Conditions Survey (ILCS), sampled almost 22,000 households across all Iraqi provinces.
Iraqis were found to be 1.5 times more likely to die from all causes after the invasion (rising from 0.5% to 0.79% per year) than in the 15 months preceding the war, producing an estimate of 98,000 excess deaths.
[166][167][168][169][170][171][172][173] Shortly after publication, the study's estimate and methodology came under criticism from a number of sources, including the United States government, academics, and the Iraq Body Count.
[199] Joshua Goldstein, professor emeritus of International Relations at American University, wrote that critics of the study "have argued convincingly that the sample method was biased.
"[200] According to University of Delaware sociologist Joel Best in his book Stat-Spotting: A Field Guide to Identifying Dubious Data, "it seems likely that [the Lancet estimate] was too large".
[201] Conflict scholars Nils Petter Gleditsch, Erik Melander and Henrik Urdal said there were "major biases" in the study, leading to oversampling of households affected by violence.
[185] The 2008 study was awarded "Article of the Year – 2008" by the Journal of Peace Research, with the jury of Lars-Erik Cederman (ETH Zürich), Jon Hovi (University of Oslo) and Sara McLaughlin Mitchell (University of Iowa) writing that the "authors show convincingly that previous studies which are based on a cross-street cluster-sampling algorithm (CSSA) have significantly overestimated the number of casualties in Iraq.
[192] Spagat noted that the lead author of the 2006 study had been censured by the American Association for Public Opinion Research for "repeatedly refusing to disclose the corresponding information for his survey".
[35][36][210][211] The Taipei Times reported on his methodology: "Al-Shemari said on Thursday [, November 9, 2006,] that he based his figure on an estimate of 100 bodies per day brought to morgues and hospitals – though such a calculation would come out closer to 130,000 in total.
"[36] The Washington Post reported: "As al-Shemari issued the startling new estimate, the head of the Baghdad central morgue said Thursday he was receiving as many as 60 violent death victims each day at his facility alone.
Dr. Abdul-Razzaq al-Obaidi said those deaths did not include victims of violence whose bodies were taken to the city's many hospital morgues or those who were removed from attack scenes by relatives and quickly buried according to Muslim custom.
He said between 100,000–150,000 people were killed in three-and-a-half years", the official said.The United Nations reported that 34,452 violent deaths occurred in 2006, based on data from morgues, hospitals, and municipal authorities across Iraq.
[215] "This poll asked about nine kinds of violence (car bombs, snipers or crossfire, kidnappings, fighting among opposing groups or abuse of civilians by various armed forces).
A September 14, 2007, estimate by Opinion Research Business (ORB), an independent British polling agency, suggested that the total Iraqi violent death toll due to the Iraq War since the U.S.-led invasion was in excess of 1.2 million (1,220,580).
[91] Van Weezel and Spagat answered, saying that the response by Hagopian et al. "avoids the central points, addresses only secondary issues and makes ad hominem attacks.
[225][226] For 2006, a January 2, 2007, Associated Press article reports: "The tabulation by the Iraqi ministries of Health, Defence and Interior, showed that 14,298 civilians, 1,348 police and 627 soldiers had been killed in the violence that raged across the country last year.
"[227] The Australian reports in a January 2, 2007, article: "A figure of 3700 civilian deaths in October '[2006]', the latest tally given by the UN based on data from the Health Ministry and the Baghdad morgue, was branded exaggerated by the Iraqi Government.
"According to a 2017 review by Keith Krause of the Graduate Institute of International and Development Studies, Geneva, Switzerland, "the consensus seems to be that around 150,000 people died violently as a result of the fighting between 2003 and 2006.
[228] The Iraq Body Count project (IBC) stated in November 2004 that "we have always been quite explicit that our own total is certain to be an underestimate of the true position, because of gaps in reporting or recording".
... in an essay Ms Ruzicka wrote a week before her death on Saturday and published yesterday, the 28-year-old revealed that a Brigadier General told her it was "standard operating procedure" for US troops to file a report when they shoot a non-combatant.
