The Measure of America

The American Human Development Project offers interactive maps for over 60 human development indicators including health, education, income, environment, housing and security. Data can be presented by state or congressional district, and can be exported as a printable PDF file. Below is an example of the education statistics; a map of congressional districts by the percentage of the population with less than a high school education:



Maps can also be created for individual states (although they might not be quite so useful for the western states with only one or two congressional districts...)
