CityLab Congressional Density Index

I created the CityLab Congressional Density Index, a novel way to categorize every U.S. Congressional District by how rural, suburban or urban it is. This tool let me — and many other major news outlets who used this same tool — quantify the much-discussed importance of the “suburbs” to the 2018 election, when Democrats ultimately won a House majority based on massive wins in suburban districts. See a host of articles using the CDI, as well as the raw data and the code I used to generate it. (CityLab, 10/05/2018)
