The Catholic population of the United States has shifted away from the Northeast and towards the Southwest, while secularity continues to grow in strength in all regions of the country, according to a new study conducted by the Program on Public Values at Trinity College. "The decline of Catholicism in the Northeast is nothing short of stunning," said Barry Kosmin, a principal investigator for the American Religious Identification Survey (ARIS). "Thanks to immigration and natural increase among Latinos, California now has a higher proportion of Catholics than New England."
The percentage of Americans claiming no religion, which jumped from 8.2 in 1990 to 14.2 in 2001, has now increased to 15 percent. Given the estimated growth of the American adult population since the last census from 207 million to 228 million, that reflects an additional 4.7 million “Nones.”
