Mississippi: In nearly every metric associated with poverty, education, employment, health risk, and insurance coverage, Mississippi has been close to the bottom for years. The state is among the ten worst for both unemployment and health insurance coverage. It has the worst poverty rate in the U.S., and by far the lowest median income in the country, at just $36,850 -- not quite half of New Hampshire's median household income. The state was also hit hard by Katrina, including the Gulfport Harbor, which the Federal Government is allotting $500 million to help rebuild. Proponents of the project expect thousands of jobs will be created in the process.
