Unstandardized choropleth map - race in the U.S.

http://www.censusscope.org/us/map_common_race.html

 

This map is an unstandardized choropleth map because although it sorts the U.S. counties by the variable of race and uses colors to distinguish the data, it does not do so in one standardized, areally-averaged way.  According to the legend, counties are shown “according to which races have a population greater than the national average”, but this does not help the viewer know exactly how big said population is or what other populations are represented in that county (again, the legend says that if more than one race “has a population greater than the average” they are shown as “multiethnic”).
