Map of Religious Diversity in America

Yet another interesting map from the Association of Statisticians of American Religious Bodies. This gets at how varied, or diverse, religious affiliation is in different regions of the country. As you can see, the areas with the most diversity also tend to have the lowest rates of adherence, which would seem counter-intuitive–at least from the perspective of Rational Choice theory. One might expect that more offerings, i.e., more types of religions, would promote greater involvement in religion.
