Not too many surprises here:

California, the Northwest and Northeast are the most irreligious parts of the nation, while the Southeast is the most religious. Of course, the correlation between poverty with religion is well-documented in the world, and with a few exceptions like parts of California, this trend holds at the state level inside the U.S. I would venture to say the same can be said for dichotomies like religion/academic performance and religion/social justice.
