Mass attendance: It’s down, again — but among whom?

Approximately every 10 years beginning in 1955, Gallup has reported a steady decline in the percentage of Catholics who report attending Mass regularly. From a high of 75 percent in 1955, the figure tailed to 46 percent in 1983-86, and reached an all-time low of 39 percent in 2014-17, according to the most recent survey issued in early April.
