Datapoint.

At the conclusion of a recent public lecture on cosmology at the University of Michigan, the lecturer conducted an anonymous poll of the 200+ attendees as to whether they believed that (1) God created the universe and is still active in guiding it, (2) God created the universe but is now absent from it, or (3) God does not exist. The result of the poll was about 30% of the responding attendees chose (1), 10% chose (2), and 60% chose (3). There may be a sampling bias - the population consisted of people getting up on a Saturday morning to attend a physics lecture - but it's an interesting result nevertheless.
