Evangelical Christians still make up a large percentage of Americans, but a growing number say they have no religion at all.
The latest poll by the American Religious Identification Survey, which was done by Trinity College, found that 15 percent of U.S. adults say they have no religion.
That number is up from eight percent in 1990, marking a growing trend of people who claim no religion.
It is also the only religious trend that is growing in all 50 states.
The Least Religious Section of the Country
According to Trinity College, Northern New England has now taken over from the Pacific Northwest as the least religious section of the country.
Vermont at 34 per cent "nones," leads all other states by a full nine points.
Seventy-six percent of those surveyed called themselves Christians, compared to 86 percent in 1990.
Evangelical Christians Make Up More Than One-Third of All American Adults
Evangelical or born-again Christians make up 34 percent of all American adults.
The survey also found the nation's huge Roman Catholic population has shifted from the Northeast to the Southwest.
"California now has a higher proportion of Catholics than New England," said one of the survey's investigators.
