Filtering Data

The OpenNet Initiative is pleased to announce the availability of our summarized global Internet filtering data as a downloadable CSV file under a Creative Commons license. The data provides an overview of the most recent ONI ratings of the breadth and depth of Internet censorship in seventy-four countries across four content categories (political, social, Internet tools and conflict/security). This release makes ONI data more accessible to researchers, journalists, and data mash-up developers.

Note: This data set has been revised since a previous release to the Millennium Challenge Corporation (MCC).
