"They say, 'I'm everything. I'm nothing. I believe in myself.' "

That quotation is from Barry Kosmin, co-author of the American Religious Identification Study (ARIS) released this week.

Cathy Grossman at USA Today has the best summary: Most religious groups in USA have lost ground.

The percentage. of people who call themselves in some way Christian has dropped more than 11% in a generation. The faithful have scattered out of their traditional bases: The Bible Belt is less Baptist. The Rust Belt is less Catholic. And everywhere, more people are exploring spiritual frontiers — or falling off the faith map completely.

"More than ever before, people are just making up their own stories of who they are. They say, 'I'm everything. I'm nothing. I believe in myself,' " says Barry Kosmin, survey co-author.

Among the key findings in the 2008 survey:

• So many Americans claim no religion at all (15%, up from 8% in 1990), that this category now outranks every other major U.S. religious group except Catholics and Baptists. In a nation that has long been mostly Christian, "the challenge to Christianity … does not come from other religions but from a rejection of all forms of organized religion," the report concludes.

• Catholic strongholds in New England and the Midwest have faded as immigrants, retirees and young job-seekers have moved to the Sun Belt. While bishops from the Midwest to Massachusetts close down or consolidate historic parishes, those in the South are scrambling to serve increasing numbers of worshipers.

• Baptists, 15.8% of those surveyed, are down from 19.3% in 1990. Mainline Protestant denominations, once socially dominant, have seen sharp declines: The percentage of Methodists, for example, dropped from 8% to 5%.

• The percentage of those who choose a generic label, calling themselves simply Christian, Protestant, non-denominational, evangelical or "born again," was 14.2%, about the same as in 1990.

• Jewish numbers showed a steady decline, from 1.8% in 1990 to 1.2% today. The percentage of Muslims, while still slim, has doubled, from 0.3% to 0.6%. Analysts within both groups suggest those numbers understate the groups' populations.

Meanwhile, nearly 2.8 million people now identify with dozens of new religious movements, calling themselves Wiccan, pagan or "Spiritualist," which the survey does not define.
