Amanda has an interesting article on cities trying to maintain and attract their educated class—and it includes a nice map of the frequency of college graduates by US counties. I just had to point out that it’s easy to spot Stevens County, where I live—it’s the orange square in a sea of paleness.
It’s too bad the huge counties out west make the western part of the country look misleadingly coarse-grained, but still, you can spot the places that attract the highly educated. Unfortunately, I don’t think it’s quite as easy as plopping a university down somewhere to turn it into a magnet for bohemians.
