Exercise 5: Choropleth Map of the Happiest States

Barbara and David Tewksbury, Hamilton College

Summary

Students create choropleth maps by creating data tables in Excel and merging them with existing shapefiles for US states; they also evaluate the effectiveness of final map layouts. You might also be interested in our Full GIS course with links to all assignments.

Higher order thinking skills goals for this activity
Applying what students have learned in previous exercises to new problems.

Description of the activity/assignment

In December 2009, a Hamilton College professor and a British colleague published an article in Science magazine that compared the self-reported happiness levels of about 1.3 million Americans with objectively determined indicators that could influence satisfaction with life (such as precipitation, violent crime, property taxes, etc.). But their paper had no map! Although this assignment is not geological, the Hamilton connection makes it a fun exercise for our students to learn how to construct choropleth maps.

Students create a data table in Excel based on the data in the Science magazine article, join it with the attribute table from an existing map of US states that has many other fields in the attribute table, and create a meaningful choropleth map. Each student makes a choropleth map layout for state happiness and a second choropleth map appropriate for USA Today on a topic of their own choosing. In class, we critique each of the maps for design, message, and cartographic elements.

Determining whether students have met the goals

Students are assessed on the accuracy of their preparation of the choropleth maps and on the clarity and accuracy of the message conveyed by their map layouts.
