Gallup Survey: Christianity Remains Dominant Religion in the United States

Majority still says religion is very important in their lives
by Frank Newport

PRINCETON, NJ — This Christmas season, 78% of American adults identify with some form of Christian religion. Less than 2% are Jewish, less than 1% are Muslim, and 15% do not have a religious identity. This means that 95% of all Americans who have a religious identity are Christians.

Bottom Line:

The United States remains a predominantly Christian nation, with 78% of all adults identifying with a Christian faith, and more than 9 in 10 of those who have a religious identity identifying as Christians. Fifteen percent of Americans do not have a formal religious identity, a continuation of a dramatic change from 50 and 60 years ago, when almost all Americans identified with a particular religion. The precise implications of the increase in the “no religious identity” segment are not clear, given that more than 9 in 10 Americans say they believe in God, and that 8 in 10 say religion is a very or fairly important part of their lives.
