ORB Survey Compared With Lancet Studies
See also: ORB survey of Iraq War casualtiesOn September 14, 2007, ORB (Opinion Research Business), an independent UK based polling agency, published an estimate of the total casualties of the Iraq war. The figure suggested by ORB, which was based on survey responses from 1,499 adults, stands at 1,220,580 deaths, with a margin of error of 2.5%. This estimate, although conducted independently, and using a different polling methodology, is consistent with the Lancet findings if accounting for the additional 14 months covered by the ORB poll.
On 28 January 2008, ORB published an update based on additional work carried out in rural areas of Iraq. Some 600 additional interviews were undertaken and as a result of this the death estimate was revised to 1,033,000 with a given range of 946,000 to 1,120,000.
This ORB poll estimate came under criticism in a peer reviewed paper called "Conflict Deaths in Iraq: A Methodological Critique of the ORB Survey Estimate", published in the journal Survey Research Methods. This paper "finds fundamental flaws in the data underpinning ORB’s estimate", and concludes that the ORB data "are not suitable for deriving any credible estimate but, given proper scrutiny, it is clear that ORB has overestimated by a wide margin.

Famous quotes containing the words orb, survey, compared and/or studies:
“Thus the orb he roamed
With narrow search, and with inspection deep
Considered every creature, which of all
Most opportune might serve his wiles, and found
The serpent subtlest beast of all the field.”
—John Milton (1608–1674)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
“The most beautiful ape is ugly when compared to a human. The wisest human will seem like an ape when compared to a god with respect to wisdom, beauty, and everything else.”
—Heraclitus (c. 535–475 B.C.)
“You must train the children to their studies in a playful manner, and without any air of constraint, with the further object of discerning more readily the natural bent of their respective characters.”
—Plato (c. 427–347 B.C.)
