The American Beliefs Study: Religious Preferences and Practices is groundbreaking research initially conducted in 2013 and then repeated in 2017 and 2021 with over 45,000 participants. This decade-long timespan and significant polling size sample have established The American Beliefs Study as a recognized leader in understanding American religious preferences and practices.

Valuable insights that reveal changing behaviors and social and moral attitudes and trends within communities of faith have been distilled into a series of unique discoveries and conclusions. Long-form articles are the American Belief Reports. And the short-form quotes and highlights for quick use.
