Entire World - Prison Population Rates per 100,000 of the national population

But be careful when reading the statistic:
(1) For a number of countries data are missing (North Korea, for instance)
(2) In a number of countries, forced labour camps (like in the former USSR) are not counted as prisons.

Both reasons artificially inflate the percentage of prisoners in US prisons reported by Donuel.

Nevertheless, in comparison to European countries with a similar method of counting the prison population in the USA seems very high.
