Classed Choropleth

























I created this map using ArcGIS

This is a map of GDP per capita by state in the years 2007.  I created this map using ArcGIS and downloaded the shapefiles from geocommons.com.  I decided to classify the data into natural breaks and created six classes.  The darker the color the higher the GDP as can be seen in California, Texas, and New York.  Data can be displayed by many different classifications and completely change the message of the map even though the same information is used.  I thought that natural breaks was the least misleading for this dataset.
