A classed choropleth map shows varying statistics that occur within specific boundaries. It follows a pattern of spatial organization of information, without showing trends particular to that information. Rather than use specific, raw data, classed choropleth maps use numerical averages to portray information.
This classed choropleth map shows per pupil expenditure for public education in North Carolina, 1994-1995.
