The Committee to Protect Journalists (CPJ) studied media freedom in dozens of countries to determine the level of access people have to information and the methods some states use to censor news and information. The CPJ used the following criteria to develop its list of the world's most censored countries: state control of the media, formal censorship rules, violence against and imprisonment of journalists, and restricted access to foreign news and the Internet.
