The New York Times recently published an (I think astonishing) piece about income inequality at elite colleges. They reported that 38 schools have more students from the top 1% of the nation's income distribution than from the bottom 60%.
I tracked down the original dataset, which came from The Equality of Opportunity Project, an organization that seems to be doing some really interesting research. Naturally, I was interested in how these data look spatially. I geocoded every college in the U.S. and mapped them based on the economic characteristics of their students. Here is an example of all schools mapped by the median household income of their students.
I created a webmap to explore several different variables within the dataset. I hope you'll check it out. You can also see the source code for this project here.
