Estimated number of victims
In the introduction, editor Stéphane Courtois states that "...Communist regimes... turned mass crime into a full-blown system of government".He claims that a death toll totals 94 million. The breakdown of the number of deaths given by Courtois is as follows:
65 million in the People's Republic of China
20 million in the Soviet Union
2 million in Cambodia
2 million in North Korea
1.7 million in Africa
1.5 million in Afghanistan
1 million in the Communist states of Eastern Europe
1 million in Vietnam
150,000 in Latin America (mainly Cuba)
10,000 deaths "resulting from actions of the international Communist movement and Communist parties not in power."
Courtois claims that Communist regimes are responsible for a greater number of deaths than any other political ideal or movement, including nαzιsm. The statistics of victims includes executions, famine, deaths resulting from deportations, physical confinement, or through forced labor.
