COVID-19 Vaccine Rollout across US Congressional Districts

The President of the United States, Joe Biden, said he plans to vaccinate 200 million Americans within the first 100 days of his presidency. As of April 14th, only 122 million Americans have received the first dose, with only 75 million fully vaccinated. Further, there are substantial geographical variations in the number of people receiving a vaccine dose. We present daily updates of vaccination metrics for US Congressional Districts. Representatives and policymakers can use this data to understand how vaccine distribution is progressing in their respective Congressional District. The Chairwoman of the Committee on Small Business, Nydia M. Velázquez, representative of New York's 7th Congressional District, underscored the importance of having COVID-19 data by Congressional Districts. We present interactive dashboards that allow users to geographically visualize vaccination indicators for the US Congressional Districts and provide this data in a tabular format.

Data Sources

The COVID-19 vaccine data displayed on our dashboards came from COVID Act Now, an independent 501(c)(3) nonprofit founded by volunteers in March 2020 to collect and publish COVID statistics. To access their data API for counties, visit their website. Since there was no official base map for the 117th congress, we used the 116th congress base map joined with the newly elected 117th Congress member names. The GIS base map for the 116th Congressional Districts came from ESRI and the spreadsheet with information about the members in the 117th congress was created by Daily Kos.

Crosswalk Methodology (Counties to 116th Congressional Districts)

To create the crosswalk between counties and the 116th Congressional Districts, our team used the Missouri Census Data Center's Geographic Correspondence Engine 2018. Since there were two county changes in 2015, we replaced the FIPS code of two counties; one in Alaska and another in South Dakota, with the following FIPS code: 02270 became 02158, and 46113 became 46102.
