Thematic maps are commonly used to link a specific theme to a geographic area. Thematic maps can come in many forms including: dot distribution maps, choropleth maps, proportional circle maps, and isoline maps. Choropleth thematic maps, like the one presented above, are used to show the distribution of a topic (in this case literacy rates) based upon boundary lines (districts).The thematic maps above were generated to reveal the female, male, and total literacy rates in India by district for the year of 2001. As you can see by comparing the differences in color distribution for the series of maps literacy rates are much higher among men than women in India for that year.
