Classed Choropleth Maps

This is a classed choropleth map of the united states showing how many males per 100 females are in each state. A classed choropleth map breaks up the subject of the map into sections and then divides it using a class system. In most of these maps the class system is broken up into colors. In this map there are four color classes that are set up separating different amounts of people.
