This week we dove more into Choropleth maps. Choropleth maps are the most commonly used thematic map. They can be used to display classified or unclassified data. The advances in analysis software makes choosing a classification much simpler for today's cartographers. ArcMap enables the user to easily chose various classifications, examine the class breaks, and view the map display in just a few clicks.
Our first map displays the population change based on each state's population change from the US Census of 1990 to 2000.

Our second map displays the population change based on regional divisions using the same US Census data as map 1.
