Since 1992, the Committee to Protect Journalists (CPJ) has published a database of killed journalists and media workers. CPJ also publishes a yearly census of journalists in prison, journalists in exile, and missing journalists.
Freedom House also publishes an index on freedom of the press, as well as a survey of civil and political rights that also covers freedom of expression. The World Justice Project’s Rule of Law Index includes data concerning fundamental rights, including freedom of expression, opinion, religion, and belief.
Operated by the Index on Censorship with the European Federation of Journalists and Reporters Without Borders, Mapping Media Freedom identifies threats, violations, and limitations faced by members of the press throughout European Union member states, candidates for entry, and neighboring countries.
