Classed Choropleth Map

This map was taken from http://courses.washington.edu/info424/Labs/ChoroplethMap.html

This is a good example of a Classed Choropleth Map.  A classed choropleth map is not really different from another choropleth map except intervals are created to express the data more simply.  In this example the one-year forecast change in jobs is set up in equal classes so that the colors can be easily differentiated.
