If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
I bet minority of people who believe in heaven actually believe in hell
Kinda: 62% of Americans believe in heaven and 53% believe in hell (source). I bet there is more data in Pew reports.
Those silly Americans :)
It seems I live in heaven already.
ETA: I blitz-googled second hand info about a World Values Survey 2000: 50 % of Finns believe in heaven, but only 25 % believe in hell. 74 % believe in god.
In a 2012 survey done by our church only 1/8 believe in "the Christian promise of eternal afterlife".
