UNSTANDARDIZED CHOROPLETH MAP

An Unstandardized Choropleth Map portrays areal data, and is not areally averaged in any way. The Areal divisions are often boundaries like census tracts, counties, states.

This Unstandardized Choropleth Map shows the acres of forage (hay, silage, etc.) The map is showing that the total hay or silage acres in each county is more regionally diffuse, since it proportionately favors the largest counties, notably those in central California, southeastern Oregon, and the northern Plains.
