Link Harvest: Religion and Education Attainment Level Globally

Of people claiming a religious affiliation, Jews are by far the most educated in the world. This, of course, has a lot to do with population concentration. Having been kicked out of every country good K-12 education is not broadly available, we are now primarily located in the U.S. and Israel. Please note that in Israel, we built the education system and prioritized it, so we should get some credit on the availability thing.

The rest is also interesting.
