2022 CDHD District Density Index
Congressional districts vary in many ways, including the extent to which they are urban, suburban or rural. To help capture that variability, our team at the Department of Population Health at NYU Grossman School of Medicine calculated the 2022 CDHD District Density Index for the newly drawn 2022 (118th Congress) congressional districts. Building on methods developed by CityLab in 2018, we categorized all congressional districts on the following gradient of household density:
Pure Rural (lowest household density)
Pure Urban (highest household density)
Why is this useful?
The CDHD District Density Index captures substantial differences in household density across U.S. congressional districts. Though we often think of health and place as a rural/urban divide, the majority of people in the U.S. live in suburban areas—loosely defined as towns and cities around major cities. In recent years, suburban population growth has been attributed almost exclusively to an increase in minority populations moving to suburbs. Valuable information would be lost by oversimplifying congressional districts into two categories – “urban” and “rural”. The District Density Index can help reveal trends and indicators of health and equity in congressional districts across the full spectrum of household density.
We analyzed a number of metrics from the Congressional District Health Dashboard using the District Density Index. Some highlights are in the graphic below. The 2022 CDHD District Density Index can be further applied to many types of analysis and datasets. We welcome use of it in your work, or please reach out with questions or to collaborate.
