Mass attendance in the US is on the decline:
An average of 39 percent of U.S. Catholics attended church weekly during the heart of the Francis papacy, from 2014 to 2017, Gallup found in a survey released April 9, which represents a significant drop from the 45 percent of Catholics who attended weekly Mass from 2005 to 2008, in the early years of the Benedict pontificate.
Go here to read the rest. So much for the Francis Effect of luring people back to the pews. However the thought occurs that for the Pope the decline in Mass attendance may well be a feature of his pontificate and not a bug.
