Anecdotally speaking, out of all my childhood, high school, college, convent, adult friends, all of my family and extended family, (all of whom were wildly Catholic in previous years), I know three people who still attend church of any kind: one is a priest, one a Benedictine nun after widowhood, and one an evangelical preacher. 

Every single article I've read in the past five years has detailed the decimation in numbers of faithful church attendees.  I think your caveat "change in reporting" is a bogus claim.
