The one that's really surprised me is the 33% (so far) atheists.
My home town has the highest proportion of atheists in the UK - 27% (
2001 census) and I rather expected to see fewer here. Overall, England has around 15% atheists.
I am disappointed to see how few believe in the blue one next to the fish.

I expected to get near 100% on that one, here at mobileread.
