There are some interesting United States-specific results as well:
60.6 percent of Americans say they have no doubt about the existence of God, and 80.8 percent agree with the statement, "I believe in God now and I always have."As an atheist/agnostic (who is also a mathematician) these poll numbers are somewhat depressing. A majority of Americans are certain of God's existence, with absolutely no evidence to support such a claim! It's not the belief in God that annoys/frightens/bothers me, it's the certitude. It demonstrates a willingness to reason using evidence that indicates a disconnect with a reality-based worldview.
The United States is the most religious of the highly developed nations, and most scholars attribute this to our tradition of separation between church and state.
54 percent of people younger than 28 said they were certain of God’s existence, compared with 66 percent of the people 68 and older.
