Pew Research Center’s Global Restrictions on Religion Data

This is not a public opinion survey, but a massive, ongoing data codification project by the Pew Research Center that measures how governments and societies around the world restrict religious beliefs and practices. By analyzing hundreds of sources for 198 countries and territories, Pew creates two seminal annual indexes: the Government Restrictions Index (GRI) and the Social Hostilities Index (SHI). This data set provides a quantitative, comparable benchmark to track trends in religious freedom, persecution, and the complex intersection of religion, law, and conflict on a global scale from 2007 to the present.
