Global Press Freedom
This map represents data from the World Press Freedom Index, created and maintained by the organization Reporters without Borders. The index ranks "the performance of 180 countries according to a range of criteria that include media pluralism and independence, respect for the safety and freedom of journalists, and the legislative, institutional and infrastructural environment in which the media operate".
All countries are color-coded based on their relative Press Freedoms score from 2014, with darker colors indicating countries with fewer freedoms and a more restricted press. The overlay indicates countries whose 2014 score was worse than their 2013 score, by a value greater than 1. It is interesting to note that the scores for some democratic European countries, including Ireland, worsened in 2014. Despite this fact, these countries are still ranked as being some of the freest in the world. The majority of countries whose scores have decreased are those that still have a comparatively free press.
Unsurprisingly, countries with the lowest press freedoms scores have more authoritarian regimes, notably China, Saudi Arabia and Iran. For countries with a more restricted press to have a significant change in press freedoms, a change of regime may also be necessary.
