Nominal area choropleth map is a thematic map that measures unordered categories. Because there is no ranking order, any color can be used to measure categories such as race, age, martial status, etc. In this example, nominal-level data is presented with distinguish colors representing which minority race occupy the highest percent of the state population. This type of map helps analysts/viewers compare data and get a simple general idea without too much specific details.
