About 82% of Americans in 2007 told Gallup interviewers that they identified with a Christian religion.
Neport breaks it down: "51% who said they were Protestant, 5% who were "other Christian," 23% Roman Catholic, and 3% who named another Christian faith, including 2% Mormon."
Coming in at 11% were those who claimed no religious identity at all, and another 2% didn't answer.

Time has shown a shift in religious camps. The new Gallup shows that the percentage of Americans who identify with a Christian religion is down some over the decades.
It is due to the higher percentage of Americans today who don't claim a religious identity.
