I was talking to Kerry Bailey the other day and – on the pretty feeble pretext that “you like maps, right” – he directed me to a fascinating post about Religion in America in which county-by-county maps of the US predeliction for various forms of religious belief have been posted and discussed. It’s such a fascinating piece of work – illuminating clumps of different religious communities around the place (Jews, Muslims, Lutherans, Catholics, Pentecostals etc). My own personal theory – that places with a lot of different religious groups living together tend to be more secular – does not seem to be immediately supported by the evidence. I wonder if there are maps like this for Europe. That would be fascinating.
