Here is an interesting map, one of several, taken from information from the 2010 American Religious Census. Taken from http://www.theblaze.com/stories/this-chart-shows-the-most-and-least-religious-counties-in-america/
I suggest before the really hard times come, that you think of moving into an area where there are lots of Christians who are living like Christians. I do not think anyone is surprised by this map. For those having trouble reading the map, yellow is the highest concentration and blue, the lowest.
