In addition to being the world’s leading executioner, China has one of its largest prison populations. The 2009 “World Prison Population List” compiled by the International Center for Prison Studies at King’s College, London, put the total number of inmates in Chinese jails at 1.57 million – larger than the population of Estonia, Guinea-Bissau, Mauritius, Swaziland, Trinidad & Tobago, Fiji, or Qatar.
