Nominal Area Choropleth Map

This is a nominal area choropleth map demonstrating the health care costs in the United States in 2006.  The lighter shaded areas are less expensive and the darker shaded areas are more expensive.  One aspect of the map is that some of the darker shaded areas are popular retirement areas and would have an older population as a whole.  I would be interested to see this map side-by-side with an economic one, to see if the areas that spend more money on health care line up with the less fortunate economic areas.
