US Faith Per City

Following the PBS series, "God in America" it only makes sense to explore what is the state of Faith in America, state-by-state? This is different from the question posed by Pew about "religion knowledge" but about identification. Not surprisingly, the Barna Group found that 3 of 4 Americans self-identify as Christians even if they don't have a church home. In their short summary on the groups webiste, they also explore a few of the cities where there are extreme differences. I've sent an email to the Barna Group to find out if there is more I can share about more cities.
