PRINCETON, NJ -- More than 9 in 10 Americans still say "yes" when asked the basic question "Do you believe in God?"; this is down only slightly from the 1940s, when Gallup first asked this question.
....
Belief in God drops below 90% among younger Americans, liberals, those living in the East, those with postgraduate educations, and political independents. However, belief in God is nearly universal among Republicans and conservatives and, to a slightly lesser degree, in the South.
....
Those under 30 are significantly less likely than older Americans to say they believe in God. It remains to be seen whether these young Americans will move toward a belief in God as they age, or instead stick with their current beliefs. Regionally, the data confirm the religious potency of the "Bible Belt," with Southerners 10 points more likely than Easterners to say they believe in God.
