How did I miss the Association of Religion Data Archives so long? Forgiving a moment that they don't include the District of Columbia in national data breakdowns, there's lots to love here. They're based at the Sociology Department of Pennsylvania State University, which is the kind of credentials I would want to use the information comfortably.
A few things I liked
- Belief in hell, as of 2005, broken down demographically, including by 2004 voting habits.
- Ditto, belief in UFOs. (Or just look at all the surveys.)
- A "family tree" of selected American Reformed denominations, which is helpful for teaching the denominational relatedness between the Unitarian Universalist Association, the United Church of Christ and other groups.
- State maps with religious and denominational statistics. Did you know South Carolina has the highest proportion of Baha'is -- almost three times that of the next most concentrated -- of any state?Â And that they are clustered in the eastern counties?
