The median income of the poorest state in the country, Mississippi, was just over half that of Maryland, the richest, and has fallen every year since it peaked in 2007, dropping $2,677 during that time. Not only did Mississippi have the highest poverty rate in the country, but 7.8% of Mississippi families made less than $10,000 in 2011, which was also the worst rate in the country. While unemployment declined in most states between 2010 and 2011, Mississippi's actually rose 0.2 percentage points, one of only two states to see an increase.
