Overestimation of Religious Attendance

  • Survey data greatly overestimates weekly religious service attendance in the U.S. Actual weekly attendance based on cell phone data is about 5%, not 20-25% as surveys claim.
  • Social desirability bias likely causes people to overreport their religiosity in surveys, inflating attendance rates.

High Annual Worship Participation

  • Around 73% of Americans enter a place of worship at least once a year, including for events like funerals and weddings.
  • This shows a high level of occasional religious engagement beyond weekly attendance.
