Is there a break down by predominant religion and Countries? With the travel ban and the accusations that it was a Muslim band it got me wondering. How many countries are there in the world and if those countries were applied a religion, what would the breakdown be?
For example, how many Muslim countries are there and how many Christian or Jewish or Hindu or atheist?
How many countries allow various religions to practice without restrictions?

So a quick google provided me this regarding Christian Countries:
