Statistical Map

 

 

Many of the maps we use are statistical maps. Statistical maps are special maps that are used when the variation in quantity of factors in a geographic area are indicated. The map above shows the percent change in resident population of the United States from 1990 to 2000. Each state shows a percent that represents there change and that is what qualifies this as a statistical map.
