Unsurprisingly Eastern Europe is substantially higher than Western or Northern Europe. Outside the scope of this topic, but what I have found the weirdest on this question is how few Latin Americans believe in Hell.
Anecdotally I've noticed that an "only heaven and purgatory" setup of folk Catholic afterlife beliefs seems fairly common among Hispanic people I've known personally.
"Purgatory. A little detour on the way to paradise. You take your mortal sins and multiply them by 50, then you add all your venal sins and multiple that by 25. I figure i'm gonna have to do 6,000 years before I get accepted into heaven, but 6,000 years is nothin' in eternity terms. It's like a couple of days down here.
