 A Statistical Map is a type of map that shows the variation in quantity of a factor in the area or geographic location. Three main types include a choropleth map, proportional symbol maps, and to map. These maps make it easier to relate info to a certain location. An example of this is the map above. It shows the resident population for each state in the U.S. in the year 2000 from the census. This is shown with shading of greens with a legend to define the interval for each shade.
