Mass Attendance

Data up to & including 2022 comes from Catholicism in Numbers, a project by the Catholic Record Society. Data after 2022 (if any) comes from the CBCEW website. Read more about our sources here.

The accuracy with which attendance is counted may vary. A person may accidentally be counted twice and figures may overstate or understate where an estimate is required, such as at very large services or if mechanical means of counting fail. Additionally, approaches to counting may vary across churches in a diocese or nation.
