Statistical maps can communicate relative scaling of map properties and it shows the relative distances between different cities, towns and general areas on the map. Statistical maps are very common to cartograms in the sense that they are used for this, and that they are the only two maps that can show relative distances through relative scaling. These maps can represent distances that are relative to properties other than physical distance. The statistical map shown illustrates the growth of internet usage in Africa from 1995 to 1996. This is the main interest of a statistical map, in that they are used to show the distances between places on maps, as well has the differences from one city to the next.
