Weekly Blog 7: Proportional Symbol Map

This is a proportional symbol map from the February 2007 issue of National Geographic Magazine. They used a typical circle as the symbol, but what makes this map interesting is the data it’s mapping. It separately maps both male and female singles. I like that the map supplements the symbols with text that highlights that the largest single male population is located on the west coast while the largest single female population is located on the east coast. In general, there are more single women on the eastern half of the United States and more single men on the western half of the United States.
