The Association of Religion Data Archives
The Association of Religion Data Archives (ARDA) website offers county, state and national reports based on the most recent US Religion Census. The site also makes available research on religion from around the world. Data included in the ARDA are submitted by religion scholars and research centers. Currently housed in the Social Science Research Institute, the College of Liberal Arts, and the Department of Sociology at the Pennsylvania State University, the ARDA is funded by the Lilly Endowment, the John Templeton Foundation, Chapman University and the Pennsylvania State University.
