MI Percent Sick with COVID

An animated map of Michigan counties between October 2021 and March 2022 showing the estimated percentage of people sick with COVID per day. The values range between 0 to 6.1 percent, with the largest values occurring in December and January.

I created this GIF to show the approximate percent of people per Michigan county (or equivalent unit, as FCI and MDOC stand for Federal Correctional Institution and Michigan Department of Corrections, respectively) that were sick with COVID-19 over time. While there is data to do so, creating a GIF from the beginning of recorded COVID-19 infections in March 2020 and present would be a very large file, so I subset this data into a six-month period to show here.


The daily COVID-19 infection data per county were acquired from https://www.michigan.gov/coronavirus/stats

The county polygons were downloaded from the US Census Bureau, and the county population numbers to calculate percentage sick were estimates from the 2020 American Community Survey.
