What is a Choropleth Map?

Choropleth maps are thematic maps that use different shading patterns and sequential color schemes for geographical areas, based on the statistical data within them. 

Data is categorized into different classes, with light colors/shades representing lower numbers and darker colors/shades representing higher numbers.

For example, if you wanted to measure population levels for each state you could assign white to states under 10 million, light blue to states between 10 – 20 million, and dark blue to states over 20 million. 

But keep in mind that for these maps to work properly, measure data with equal intervals.

Types of Data Used for Choropleth Maps

Use choropleth maps with a number of different types of data. To do so, just remember the three basic requirements when selecting data for this type of map:

  1. The geographic regions are all related (zip codes, counties, states, etc.)
  2. No raw data. Only use processed data.
  3. The data needs to apply across the whole map.

Assuming your data set adheres to the above rules a choropleth map will accurately represent it.

Advantages and Disadvantages of Choropleth Maps

While choropleth maps work perfectly for some projects, they aren’t suited for all. To get the most out of your data, experiment with a variety of maps to find the formats that work best for you.

Advantages

  • Simple to Prepare: Compared to other types of maps, choropleth maps are quick to create and set up.
  • Easy to Understand: Assuming you keep the number of classes low, someone can look at your map and quickly determine your findings without difficulty. 
  • Popularity: Choropleth maps are also very widely used, so most people are familiar with them. This means you don’t have to explain how they work in order for people to understand them.
  • Measure Many Regions at Once: Their simplicity means you can place data for a large number of geographic areas on one map while still keeping everything comprehensible.

Disadvantages

  • Not Ideal for Showing Total Values: Choropleth maps give you a generalization of your data, not exact amounts. So, if you want to know the total value for a specific piece of data, choose another type of map.
  • Easily Manipulated: The results shown on the map largely depend on the data classes the creator chooses, so the map maker can manipulate the data to make a point.
