Zipskinny!

http://zipskinny.com/ points to data on towns such as level of educational attainment, age ranges, household income, and so on. It presents census data through a simple zip-driven interface.

After you've done a search, try some of the colored tabs (top and bottom) for more features. The "compare with other zips" feature is especially interesting.

What? What's this have to do with education, or SAD 46?

Well, it might just help answer the old question, so relevant at budget time, of just how it is that you get blood out of a turnip!
