"• This report shows that more than 10.77 million people are held in penal institutions throughout the world, either as pre-trial detainees/remand prisoners or having been convicted and sentenced. Figures for Eritrea, Somalia and the Democratic People’s Republic of (North) Korea are not available and those for China are incomplete (see footnote to Table 3 concerning China). Also missing are prisoners held under authorities not recognised internationally and those pre-trial prisoners who are held in police facilities and not included in published national prison population totals. The full total is therefore higher than 10.77 million and may well be in excess of 11.5 million.

"• There are more than 2 million prisoners in the United States of America, 1.69 million in China (plus unknown numbers in pre-trial detention and other forms of detention), 811,000 in Brazil, 478,000 in India, 471,000 in the Russian Federation, 309,000 in Thailand, 291,000 in Turkey, 266,000 in Indonesia, 220,000 in Mexico, 189,000 in Iran, and 165,000 in the Philippines."
