That map is pretty sloppy, at least when it come sto the US. What the hell is "various Christians" supposed to mean? There are only Catholics and Protestants in the US in any large number. That map makes it look like most Americans are "various Christian Churches". That's not the case. Most Americans are Protestant. Something like 2/3 of Americans are Protestant. The map make sit look like the number of Protestants is

The map also seems to be having some difficulty pinpointing areas that are substantially Shia Islam as well.

The source of the map is the World Christian Trend! This explains its sloppy face...
European countries are "traditionnaly" christians.. I mean that their people have a bigger percentage og atheists, agnostics and oter stuff...

The most hilarious thing was the forecast! :D It's well known that islam has the biggest conversion rate but even if we only consider the demographic factor, their pronostics don't make sense!

craig, what about all the baptist, evangelican, 7th day adventist, unless you are considering them all under the protestant wing.
Have anyone notices how tiny the jewish color is, I mean I can't even see it, even in Israel, talk about occupation...
