I don’t think there is a “Francis” effect going on at all. In our diocese its been steady and then increasing over the last few years. Our diocese (in PA) isn’t a particularly large one and we have 2 RoE at the Cathedral. This year each had about 500, with the overwhelming majority being converts from other Christian faiths.
On the other hand, if there is some increase because of Pope Francis, that’s awesome! Nothing wrong with that at all IMO. After all, he’s here to guide us all to Christ right!?
Also I can tell you that at least in our parish its solid catechesis and a great RCIA program. We have our Priest, Deacon (also a college professor), Nun who has her own show on EWTN and 2 Catechists. We are very blessed!
I have spoken to even cradle Catholics who have either fallen away or have been going thru the motions so to speak. I share with them all that I have learned from my teachers and most of them are returning to the Church and those who haven’t left are getting more involved and learning more about the faith. My family who is Protestant has seen the changes in my life and are amazed. As a result they have been asking me more about the Catholic faith!

Not suggesting they are going to be converting any time soon, but at least they are interested in dialogue and learning the Truth. Although secretly and selfishly I hope they will be converts some day. But I’ll let that to the Holy Spirit!
