The Government Religious Preference dataset (GRP) measures government-level favoritism toward, and disfavor against, 30 religious denominations. The unit of observation is the state-year. A series of ordered categorical variables index the state's institutional favoritism in 28 different ways. Those 28 variables are combined to form five composite indices for five broad components of state-religion: official status, religious education, financial support, regulatory burdens, and freedom of practice. The five components' composites in turn are further combined into a single composite score, the GRP score. All of this is done for each of the 30 religious denominations covered in the dataset. The total number of data points is approximately 42 million, distributed in six data files.
