More Evidence on U.S. Catholic Church Attendance.

When U.S. respondents to soda surveys are asked to report their attendance at religious services, approximately 40% of Protestants and 50% of Catholics claim to attend church in any given week. These survey findings have been widely disseminated. They are prominently and broadly cited though out scholarly, popular and textbook writing on American religion. Such extensive interest makes it all the more important to investigate whether these rates give a true or a distorted picture of religious practice in the United States. A recent paper has shaken confidence in the self-reported church attendance rates. Using counts of actual attendees at religious services rather than self-reports, the study has argued that the true weekly U.S. church attendance rate is approximately half the rate implied by the self-reports. The line of investigation is continued by collecting count-based church attendance data from an additional 31 Catholic dioceses. Including 17 dioceses reported on in the original paper, one is able to calculate count-based church attendance rates in 48 U.S. Catholic dioceses.
