According to the Pew Forum on Religion and Public Life survey, the Roman Catholic Church has lost more members than any other faith tradition in the United States. Some highlights:
- The Roman Catholic Church has lost more members than any faith tradition because of affiliation swapping, the survey found. While nearly one in three Americans were raised Catholic, fewer than one in four say they’re Catholic today. That means roughly 10 percent of all Americans are ex-Catholics.
- The share of the population that identifies as Catholic, however, has remained fairly stable in recent decades thanks to an influx of immigrant Catholics, mostly from Latin America. Nearly half of all Catholics under 30 are Hispanic, the survey found.
- On the Protestant side, changes in affiliation are swelling the ranks of nondenominational churches, while Baptist and Methodist traditions are showing net losses.
- The religious demographic benefiting the most from this religious churn is those who claim no religious affiliation. People moving into that category outnumber those moving out of it by a three-to-one margin.
- The majority of the unaffiliated — 12 percent of the overall population — describe their religion as “nothing in particular,” and about half of those say faith is at least somewhat important to them. Atheists or agnostics account for 4 percent of the total population.
- More than one-quarter of American adults have left the faith of their childhood for another religion or no religion at all, the survey found. Factoring in moves from one stream or denomination of Protestantism to another, the number rises to 44 percent.
Parenthetically, I was not able to see the time period covered by the survey.
