A little numbers-crunching from CARA at Georgetown in February found some heartening news:
Aggregating over multiple years and studies, CARA’s national surveys of self-identified adult Catholics (CARA Catholic Polls or CCP) indicate that 8% entered the Church as adults. Three-quarters of these adults (75%) say they went through an RCIA program. Thus, we can assume that 6% of all adult self-identified Catholics are converts who have been through RCIA. How many Catholic adults are there? According to the Census, the U.S. population in 2014 was 318.9 million. Of this, 245.2 million were adults. CARA’s aggregation of national surveys for 2014 (Pew, Gallup, PRRI, GSS) estimates that 23.2% of this population self-identified as Catholic at that time. This means there were 56.9 million Catholic adults. Six percent of these adults, who we estimate entered as adults and went through RCIA, represents a total population of 3,413,199. We know about 4 million have entered the faith as adults since 1986. Surely, some of these people have passed away or moved outside of the United States (…also some who entered the faith in another country may have moved to the U.S. and been captured in our surveys). Yet, even if assume none have passed away or left, then 84% of these entries still self-identify as Catholic and as we have described before they tend to be very active in the faith. For example, 62% attend Mass at least once a month (compared to 48% of cradle Catholics) and 54% go to confession at least once a year (compared to 24% of cradle Catholics). So why do so many RCIA directors, pastors and others assume retention and activity is so low? Why don’t they see the people they formed in their pews? Because many really did leave that parish. But that doesn’t mean they are not Catholic and not active in their faith in another parish. Remember 72% indicate one of the main reasons they convert to Catholicism is marriage. What do people do in and around the time they get married? They move, buy homes, start families, start careers, and have kids. Don’t take it personally that they aren’t in your pews. It’s a safe bet that they are in another parish’s pews. Actually it’s more than a safe bet. Eleven percent of people CARA has surveyed nationally in-pew, during Mass, self-identifies as a convert to Catholicism. That is higher than their share within the self-identified Catholic population (8%). This is because they are more often attending Mass than other Catholics. The 84% retention estimate is likely on the low and conservative end.
