An original estimate of the final death toll ranged from 15 to 40 million. According to Frank Dikötter, a chair professor of humanities at the University of Hong Kong and the author of Mao’s Great Famine, a book which details the Great Leap Forward and the consequences of the strong armed implementation of the economic reform, the total number of people who were killed in the famine which lasted from 1958 to 1962 ran upwards of 45 million. Of those who were killed in the famine, 6–8% of them were often tortured first and then prematurely killed by the government, 2% of them committed suicide and 5% of them died in Mao’s labor camps which were built to hold those who were labelled “enemies of the people”
