"Worldwide, 132 journalists, or 60 percent, were jailed on anti-state charges such as subversion or terrorism. That is far higher than any other type of charge, such as defamation or insult, but roughly in line with the proportion of anti-state charges in previous years," the report reads.
A total of 220 journalists currently remain in jail, according to the study, which also indicates that 20 percent of those detained were arrested without trial.
Ethiopia, Vietnam, Syria, Burma, Azerbaijan, and Turkey have also imprisoned more journalists in 2014.
In the latest move last week, Turkish police conducted nationwide raids, detaining 27 people, including journalists, TV producers and police officers. The raids followed allegations that US-based Muslim cleric, Fethulla Gulen, was attempting to overthrow Recep Tayip Erdogan's government. Most of the detained journalists were Gulen supporters. The Turkish foreign minister claimed that the journalists were arrested for their alleged involvement in a "crime syndicate".
