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.
High-speed rail in China
On one hand, the demand of high-speed rail in China steadily increases over time. In 2012, the average occupancy rate of high-speed rails in China is 57%. This percentage increases to 65%, 69.4% and 72.1% in the year of 2013, 2014 and 2015, respectively. Up to February 2016, high-speed rails covers nearly 200 thousand kilometers. On the other hand, however, public concerns and questions about the high-speed rail development from various perspectives have been raised as well.
