Huffington Post today has a slide show showing the top 52 cities in the United States ranked by the degree of interfaith diversity.
I was intrigued to find Detroit ranked #1 on the list. San Francisco was #5. Sacramento #6, Los Angeles #15 and San Jose #29, coming in even behind Salt Lake City.
The cities are ranked according to the Simpson's Diversity Index (which I trust is not created by the TV show). For each city, the survey lists the number of Roman Catholics, Muslims, Jews, Protestants, "Other Christians" and, interestingly enough, Mormons in their own category.
