The following comes from this list of the top fifty countries containing the largest percentage of people who do not believe in God.

• 1. Sweden - 85%
• 2. Vietnam - 81%
• 3. Denmark - 80%
• 4. Norway - 72%
• 5. Japan - 65%
• 6. Czech Republic - 61%
• 44. United States - 9%

The figures don't necessarily represent the number of atheists. I'm not entirely sure how the study was conducted, but I know it didn't distinguish between agnostic and atheism, or other forms of non-deistic spirituality, for that matter.

Although the numbers themselves are interesting, it would be fascinating to see cross tabulations with other demographics. Are there any correlations between wealth, political structure, etc. and whether or not the inhabitants of a nation believe in God? How do the "Godless" societies rank in terms of indicators of societal health (e.g., crime rates, public health, percent in poverty)? Where does the Flying Spaghetti Monster fit into all of this?
