Analysis of information sources in references of the Wikipedia article "Cambodian Civil War" in English language version.
An estimated 275,000 excess deaths. We have modeled the highest mortality that we can justify for the early 1970s.
Subsequent reevaluations of the demographic data situated the death toll for the [civil war] in the order of 300,000 or less.cf. "Cambodia: U.S. bombing, civil war, & Khmer Rouge". World Peace Foundation. 7 August 2015.
On the higher end of estimates, journalist Elizabeth Becker writes that 'officially, more than half a million Cambodians died on the Lon Nol side of the war; another 600,000 were said to have died in the Khmer Rouge zones.' However, it is not clear how these numbers were calculated or whether they disaggregate civilian and soldier deaths. Others' attempts to verify the numbers suggest a lower number. Demographer Patrick Heuveline has produced evidence suggesting a range of 150,000 to 300,000 violent deaths from 1970 to 1975. In an article reviewing different sources about civilian deaths during the civil war, Bruce Sharp argues that the total number is likely to be around 250,000 violent deaths. ... [Heuveline]'s conclusion is that an average of 2.52 million people (range of 1.17–3.42 million) died as a result of regime actions between 1970 and 1979, with an average estimate of 1.4 million (range of 1.09–2.16 million) directly violent deaths.
