I think this Pew survey of American religious practice will get a good bit of attention, even beyond thefront page of today's NYT.The two most striking findings: 1. The increasing number of non-affiliated and/or non-religious people. 2. The discovery that one-third of adults raised as Catholic no longer consider themselves Catholic. (The total Catholic percentage of the population is steady because of immigration.) Or put another way: 10% of the American population is ex-Catholic.
