Unstandardized choropleth maps display data that is not ranked. Meaning, there is no class that is greater or less than the other. These maps do have classes that are defined by specific value but there is no ranking. This style of map can also include raw data that has not been areal averaged. The data is usually not compared to other figures or data such as percent population. This map depicts which counties in North Carolina have more complete architectural surveys. The colors relate to the average status (completeness) of the architectural survey.
