Thematic Map

This particular map is a Thematic Map because as the name suggests, it represents a theme about a certain area.  A Thematic Map shows information about a particular subject superimposed over a base map.  In this case, the image is reflecting the population change across America over a six year span.  Many different sets of data can be represented in the form of a thematic map, and there are several types of thematic maps.  Often maps can be labeled thematic in what they're representing as well as another kind of map in how the information is being reflected.
