a psychological tour of the U.S.

From the Boston Globe: Where do all the neurotics live? provides a great look at the various personality types across the nation.

Economic geography has a lot to do with it:

Greater Chicago is a center for extroverts and also a leading center for sales professionals. The Midwest, long a center for the manufacturing industry, has a prevalence of conscientious types who work well in a structured, rule-driven environment. The South, and particularly the I-75 corridor, where so much Japanese and German car manufacturing is located, is dominated by agreeable and conscientious types who are both dutiful and work well in teams.

This was fresh from The Buzz yesterday (thanks Brian).
