Jim, you're such a provocateur!
Actually, at the source link you can enlarge and/or make a nice one-page pdf file for printing.
Quite a bit of food for thought in the graphic. For example, compare the numbers of Catholics to Muslims. Or consider that the chart shows more total Secular/Irreligious/Agnostics/Atheists than the total of all non-Catholic Christians. And that the total of "Dharmic" adherents (Buddhists and Hindus combined, basically) is almost identical to the total of Christians. And did you know there were that many more Sunnis than Shiites? (Shia? Chia?)
And of course, it's good that the 745 Samaritans were not left out, but Scientologists will be much offended for their lack of specific mention.
Also, the geographical representations at the bottom are worth considering, no matter one's perspective.
