Comparison of United States incarceration rate with other countries
The incarceration rate of the People's Republic of China varies depending on sources and measures. According to the World Prison Brief, the rate for only sentenced prisoners is 118 per 100,000 (as of 2015). The rate for prisoners including estimations for the number of pre-trial detainees and those in administrative detention is 164 per 100,000 (as of 2015). In a 2010 interview Harry Wu, a U.S.-based human rights activist and ex-Chinese labor camp prisoner, estimates that "in the last 60 years, more than 40–50 million people" were in Chinese labor camps, but that period includes the mass incarcerations of the 1950s or the Cultural Revolution (1966-1976) and is not representative of modern China.
Incarceration in the United States
With around 100 prisoners per 100,000, the United States had an average prison and jail population until 1980. Afterwards it drifted apart considerably. The United States has the highest prison and jail population (2,121,600 in adult facilities in 2016), and the highest incarceration rate in the world (655 per 100,000 population in 2016). According to the World Prison Population List (11th edition) there were around 10.35 million people in penal institutions worldwide in 2015. The US had 2,173,800 prisoners in adult facilities in 2015. That means the US held 21.0% of the world's prisoners in 2015, even though the US represented only around 4.4 percent of the world's population in 2015,
