12/28   Looking for a religiousness density map based on county. Is there
        one out there?
        \_ Try http://search.census.gov/search?utf8=%E2%9C%93&affiliate=census&query=religion+by+county
           \_ Public Law 94-521 prohibits us from asking a question on religious
              affiliation on a mandatory basis; therefore, the Bureau of the Census
              is not the source for information on religion.

           This is some interesting by state data.
