Its from the Lancet Report, about a year and a half ago. That total number of civilian war dead is something like 4 times the latest UN report released this month. The methodology is also crap. They apparently identified 33 random clusters, some in Fallujah, and asked residents how many people in their family died and by whom. Heres an interesting critique:
When asked about the methodological soundness of using a self-report survey of a population that believes Yassar Arafat is a hero, Jews control the world, the US is in Iraq to steal oil, beheading videos are sexier than porn, and that whenever Abu Musab al-Zarqawi kills a hostage 'it's the Yankee imperialist's fault', the authors responded by saying, "Timmy."
Thanks very much for this information; yes, it was in reference to the Lancet report.
