Thematic maps have been used for a number of different things like population, elections and many more. Each color of this map type is set to a specific category. The map above is a Thematic map it describes the median age in the Northeast. Each color of this map is a different age group, so all you do is find the age group you are looking for, then get the color that represents the age and discover where on the map that the most people are within that group. Each thematic map should have legend or key so that you can know everything you need to know about the map.
