UNDATED (AP) - A wide-ranging study on American religious life suggests that the percentage of Christians in the nation has declined. And more people say they have no religion at all.
The American Religious Identification Survey reports that more than three-fourths of U.S. adults call themselves Christians -- a shrinking percentage owing to sharp declines among mainline Protestants.
But more than one-third of American adults identify themselves as evangelical or born-again.
Fifteen percent of respondents said they had no religion -- a category that increased in every state.
The researchers say their margin of error is plus or minus one-half of one percent.
