GIS SNAPSHOTS — Volume 20 — April 27, 2023
PEER REVIEWED
Four map panels correspond to the racial or ethnic majority of zip codes’ populations. The maps include shading for the following equity index values: <0.70, 0.70–0.79, 0.80–0.99, 1.00–1.25, and >1.25. Most majority Black zip codes account for a larger share of the city’s deaths due to COVID-19 than its vaccinated population while most zip codes with White or Asian majorities account for a larger share of the city’s vaccinated population than deaths due to COVID-19. Four of 7 zip codes that experienced improvements in equity since June 2021 are majority Hispanic. In 3 zip codes, the Black and Hispanic populations together form a majority but neither group alone accounts for a majority.
COVID-19 vaccination equity index by zip code, Chicago, Illinois, July 2022, and improvements in equity index since June 2021. The maps display the COVID-19 vaccination equity index measure, calculated as the relative ratio of vaccinations to deaths by zip code in Chicago through July 2022. The map outlines in bold the 7 zip codes that experienced improvements of more than 0.1 as measured by this equity index from June 2021 to July 2022.
