So I searched for France and found a more detailed entry. I know few French people are religious, but the statistics on Simple English Wikipedia did surprise me:
The population is about 51% Roman Catholic, and 31% of people are agnostics or atheists. 4% are Muslim, 3% say they are Protestant and 1% say they are Jewish. 10% are from other religions or do not have an opinion about religion.
According to a Poll in 2005:
34% of French citizens responded that “they believe there is a God”.
27% answered that “they believe there is some sort of spirit or life force”.
33% answered that “they do not believe there is any sort of spirit, God, or life force”.
So a lot of the French Roman Catholics aren’t so sure there is a God. I guess they’re Cultural Catholics. It’s rather sad.
