The ARDA is an exceptional resource for learning more about sociological elements of religion. Find out how many people in the U.S. believe in God or what percentage affiliate with various religious traditions. Access dozens of additional survey questions to add to your question bank, read articles on religious trends, or search the sociology of religion bibliographic database in the Religion Research Hub. Possibilities abound. All of this great social scientific research on religion is available for free via the ARDA thanks to funding and leadership from the Lilly Endowment, the John Templeton Foundation, and the Pennsylvania State University.
