State of the States: Importance of Religion: "Vermont, New Hampshire, Maine, and Massachusetts are the least religious states."
This is dramatic because these states were pioneered by people seeking explicitly to practice religion. Of course, as far as I can tell the survey didn't count things like Marxism, Secular Humanism and Global Warmism as religions. Man is incurably religious which is why all "philosophies" take on the structures of religion (e.g. clergy, sin, penance, apocalypse) and are no more or less verifiable scientifically than traditional religion.
