What % Of U.S. Adults Have College Degrees?

In a way the numbers seem very low to me. Then when I think about it some more, maybe not.

Some eye-opening stats. I guess when many urban high schools are graduating 50% or even less of their students (RCSD, I'm looking at you), that will pull the numbers down fast. Thanks to @dragonflyeye (http://dragonflyeye.net/) for the link.
