Show USA is a great map service produced by the same people that brought us Show World. Show USA has five categories of data from which you can choose a data set to be represented on a map. The regions and states on the map change size based on the data set selected. For example, if you choose “population over 65” the map makes California and Florida large while shrinking the size of Montana and Wyoming.
You can access both Show USA and Show World here.
Applications for Education
Show USA and Show World are good reference tools and good tools for creating visual representations of demographic, economic, and scientific data.
