Thematic map depicting population in the Eastern U.S.

This image is that of a thematic map.  A thematic map is a tool that lets us view data (such as population data from the U.S. census bureau) graphically.  This thematic map gives us the median age of nearly half the states in the country as was reported through the 2000 census.  It is interesting to note that Florida is the lone southern state to have a median age above 37.1.http://www.lib.wsc.ma.edu/censusaff.htm
