America's Unfaithful Faithful By DAVID VAN BIEMA

A major new survey presents perhaps the most detailed picture we've yet had of which religious groups Americans belong to. And its big message is: blink and they'll change. For the first time, a large-scale study has quantified what many experts suspect: there is a constant membership turnover among most American faiths. America's religious culture, which is best known for its high participation rates, may now be equally famous (or infamous) for what the new report dubs "churn."
The report, released today by the Pew Forum on Religion & Public Life, is the first selection of data from a 35,000- person poll called the U.S. Religious Landscape Survey. Says Pew Forum director Luis Lugo, Americans "not only change jobs, change where they live, and change spouses, but they change religions too. We totally knew it was happening, but this survey enabled us to document it clearly."
According to Pew, 28% of American adults have left the faith of their childhood for another one. And that does not even include those who switched from one Protestant denomination to another; if it did, the number would jump to 44%. Says Greg Smith, one of the main researchers for the "Landscape" data, churn applies across the board. "There's no group that is simply winning or simply losing," he says. "Nothing is static. Every group is simultaneously winning and losing."
For some groups, their relatively steady number of adherents over the years hides a remarkable amount of coming and going. Simply counting Catholics since 1972,for example, you would get the impression that its population had remained fairly static - at about 25% of adult Americans (the current number is 23.9%). But the Pew report shows that of all those raised Catholic, a third have left the church. (That means that roughly one out of every 10 people in America is a former Catholic, and that ex-Catholics are almost as numerous as the America's second biggest religious group, Southern Baptists.) But Catholicism has made up for the losses by adding converts (2.6% of the population) and, more significantly, enjoying an influx of new immigratns, mostly Hispanic.
An even more extreme example of what might be called "masked churn" is the relatively tiny Jehovah's Witnesses, with a turnover rate of about two-thirds. That means that two-thirds of the people who told Pew they were raised Jehovah's Witnesses no longer are - yet the group attracts roughly the same number of converts. Notes Lugo, "No wonder they have to keep on knocking on doors." .............(more}
