Pew is out with a new survey of religion in America. I’ve only skimmed it so far, but it has lots of interesting stuff. Note for example that this survey suggests that are marginally more self-identified Buddhists in America than Muslims (this is probably a function of the fact that Buddhism, and generally Buddhist ideas and concepts, have a much wider appeal to white Americans than Islam, whose “product” is less strong differentiated from forms of Christianity).
Check the methodology.
