The study, "Faith in Flux," which was conducted by Pew Forum on Religion & Public Life, is a follow-up to the "U.S. Religious Landscape Survey" that was based on research in 2007 and then released in 2008. Between Oct. 3 and Nov. 7 of last year, 2,800 people, who were among the 35,000 who were originally surveyed in 2007, were re-contacted.
The results also reveal that:
- Most people who change their childhood faith do so before age 24.
- Fifteen percent of Americans who were raised Protestant are now affiliated with a different Protestant denomination.
- Nine percent of Americans who were raised Catholic are no longer affiliated with the Catholic faith. Five percent are now Protestant and four percent are not affiliated with any church.
- Seven percent of Americans who were raised Protestant are no longer affiliated with any religion.
- Sixteen percent of Americans say they are now unaffiliated with any religion.
