get over half the world's population inside the circle. Basically, over half the world's population is concentrated in an area of the map which is dominated by Buddhism, Taoism, and Hinduism... and the third most populous country on the planet is Muslim.

Now, OUTSIDE of that circle, you have almost half the population spread out across the rest of the map, dominated by Christianity and Islam. And the most populous areas of THAT world, are Christian. That is not debatable.

The bottom line is, about a third of the world's people are Christian and a little less than a quarter are Muslim.

Now, if I may point out something else for those who think Muslims are terrorists and whatnot, I would point out that, while something like 90% of the world's terrorists are Muslim, they represent a tiny proportion of Islam as a whole. If there are a million terrorists in the world, and I sincerely doubt there are anywhere near that many, a million would represent something like 0.056% of the entire Muslim population in the world. So, while a vast majority of the world's terrorists are Muslim, an even more vast majority of Muslims are not terrorists... so quit treating them like they are.
