An unclassed Choropleth map is similar to a classed choropleth map in that it divides an area into different groups and then colors it in to show differences in things such as population or rainfall. The difference however, is that an unclassifed map does not divide into quadrents meaning red equals 1-5, blue equals 6-10. Unclassified maps use a constant darkness scale that changes each individual percentage with a change in darkness or color. This is an Unclassifed choropleth map showing the mortality rates in Europe.
