Anecdotally, I see a lot of of dwindling in membership (and, it at least one, even schism) in established protestant congregations (Methodist, Presbyterian, Lutheran, Anglican) - many of those buildings having literally shut down - and converts coming to my local Catholic parish, as well as returning practitioners of the faith.

It's hard to imagine the Catholic church being as prominent in the world as it once was, of course, but as member myself, the last couple of years give me hope that we might again start growing.
