Mappa Fides

I linked to one mapping site recently. Here’s another, discovered via Daily Dish: Mapping Religion in America. The predominance of this or that religious denomination sheds light on the history of the settlement of the nation by this or that set of ethnic groups. There are some interesting quirks, such as a concentration of Jews in central Idaho. The west is predominately Catholic. Red = Baptist, Blue = Catholic. But it doesn’t correspond exactly to red state/blue state.
