33. Unclassed Choropleth Map

Unclassed choropleth maps differ from classed choropleth maps only in the sense that there are not a set number of color gradations. The maps above compare classes and unclassed choropleth maps. On the left one can see that there are five classes to identify the percentage of people married by county. On the left there is no scale other than the darker the color the higher the percentage.
