Unstandardized choropleth maps

Unstandardized choropleth maps are maps that are unordered. One category is not higher or lower than the other.

Standardized choropleth maps

A standardized choropleth map is a map that shows the distribution of a data, usually with various colors; color changes are correlated to the density per unit area of the data.
