A single map is but one of an indefinitely large number of maps that might be produced for the same situation or from the same data. The maps used in this collection are called thematic maps. One of the reasons for focusing on females is that most cultural maps we see show the data in terms of both males and females. This makes it appear that females and males are experiencing the topic under question to the same degree. There are several types of thematic maps.
Qualitative maps show non-numerical information about a particular topic.
For example, a map that shows whether abortion is allowed in a country or not is a qualitative map. Quantitative maps, on the other hand, show the distribution of a single topic based on statistics. Choropleth maps are a type of quantitative map and are the most common map type used in this presentation. The resulting map shows a clear picture of the distribution of the mapped item, but there are 2 important points that must be kept in mind when viewing choropleth maps. First, since data comes from political entities, the number for each region is an average.
