Well, that's what this latest Gallup poll says. Of course, that's by their definition of "non-religious":
Gallup classifies 40% of Americans nationwide as very religious -- based on their statement that religion is an important part of their daily life and that they attend religious services every week or almost every week. Another 32% of Americans are nonreligious, based on their statement that religion is not an important part of their daily life and that they seldom or never attend religious services. The remaining 28% of Americans are moderately religious, because they say religion is important but that they do not attend services regularly or because they say religion is not important but still attend services.
Note that I've seen other studies which indicate that Americans don't attend church as often as we say we do, but that's another issue.
Unfortunately, I couldn't find any comparison with previous years, so I don't know whether this is a good sign or not. After all, I suspect that most of these people classified as "non-religious" would still claim they believed in God.
They might never go to church, and never think about religion at all, but taking that next step to admitting non-belief is too much for most people. And many Americans who never go to church still seem to grant automatic respect to clergymen. So I don't want to make too much of this.
Still, it's better than I would have guessed. Don't you agree?
According to Gallup, there really is a Bible Belt. Mississippi is the most religious state in the Union, and all of the top ten most religious states are in the South, with the sole exception of Utah (though Gallup says that Oklahoma straddles the line between the South and the Midwest).
The least religious states tend to be in New England or the far West, with Vermont and New Hampshire taking the honors. Note that Nebraska is 18th in religiosity, less religious than Kansas, but more than Iowa.
Oh, and you could probably guess this:
Religion is related to politics in today's America, and it is clear from a glance at Gallup's State of the States map that the most religious states in the union generally are the most Republican, while the least religious states skew more toward the Democratic Party.
