Following the Pew study, many now often frequently cite that “one in ten Americans” is formerly Catholic. What these individuals seem not to realize that one in four is Catholic. In general people don’t have a good understanding of the sheer size of the Catholic population. For example, I have noted elsewhere that the recent trend in infant baptisms is down slightly. However, there are still enough people joining the Catholic Church each year to sustain the population. In 2009, The Official Catholic Directory reported 857,410 infant baptisms, 43,279 adult baptisms, and 75,724 receptions into full communion in U.S. dioceses. This totals 976,413 in one year (and does not include the number of former Catholics who have returned to the faith or immigrants who entered the Church elsewhere and who moved to the U.S. in this year). To put that in context, the number of new Catholics in 2009 would make this one-year cohort of new Catholics approximately the 26th largest membership Christian church in the United States (also similar in size to all Jehovah’s Witnesses or about half of all Muslims in the United States).
