ZIP Code boundaries in Chicago. The data can be viewed on the Chicago Data Portal with a web browser. However, to view or use the files outside of a web browser, you will need to use compression software and special GIS software, such as ESRI ArcGIS (shapefile) or Google Earth (KML or KMZ).

NOTE: Starting 1/5/2021, the pattern used to populate the unique Row ID column is changing but values will still be unique. Please see http://dev.cityofchicago.org/open%20data/data%20portal/2021/01/05/covid-by-zip-rowid.html for more information. -- This is the place to look for important information about how to use this dataset, so please expand this box and read on!-- This is the place to look for important information about how to use this dataset, so please expand this box and read on!

This is the source data for some of the metrics available at https://www.chicago.gov/city/en/sites/covid-19/home/latest-data.html.

For all datasets related to COVID-19, see https://data.cityofchicago.org/browse?limitTo=datasets&sortBy=alpha&tags=covid-19.

Only Chicago residents are included based on the home ZIP Code as provided by the medical provider. If a ZIP was missing or was not valid, it is displayed as "Unknown".

Confirmed cases are counted based on the week the test specimen was collected. For privacy reasons, until a ZIP Code reaches five cumulative cases, both the weekly and cumulative case counts will be blank. Therefore, summing the “Cases - Weekly” column is not a reliable way to determine case totals. Deaths are those that have occurred among confirmed cases based on the week of death.

For tests, each test is counted once, based on the week the test specimen was collected. Tests performed prior to 3/1/2020 are not included. Test counts include multiple tests for the same person (a change made on 10/29/2020). Only molecular (PCR) tests reported to CDPH through electronic lab reporting are included. Early in the pandemic, electronic lab reporting took time to onboard and testing availability was severely restricted. As a result, numbers prior to May 1, 2020 will be an undercount of community infection.

The “Percent Tested Positive” columns are calculated by dividing the number of positive tests by the number of total tests . Because of the data limitations for the Tests columns, such as persons being tested multiple times as a requirement for employment, these percentages may vary in either direction from the actual disease prevalence in the ZIP Code.

All data are provisional and subject to change. Information is updated as additional details are received.

Case, test, and death metrics for a single Chicago ZIP Code, which can be selected from the filter area.

In comparing charts for different ZIP Codes or for the same ZIP Code captured at different times, please note that the y-axis scales adjust to the data for readability so may be different between two images.

Due to a 5/29/2020 change described at http://dev.cityofchicago.org/open%20data/data%20portal/2020/05/29/covid-19-weekly-ZIP-percent-positive.html, Percent Tested Positive - Weekly percentages may have changed from previous versions of this chart.

Due to a 10/29/2020 change discussed at https://www.chicago.gov/content/dam/city/depts/cdph/statistics_and_reports/COVID%20POSITIVITY%20RATE%20CHANGES%20102720.pdf and in the description of the “Source Data” dataset, the “Percent Tested Positive – Weekly” line in this chart is based on individual tests, not unique people as it was previously. Therefore, it may differ significantly from versions of this chart printed or saved before this change.

To compare ZIP Codes to Chicago Community Areas, please see http://data.cmap.illinois.gov/opendata/uploads/CKAN/NONCENSUS/ADMINISTRATIVE_POLITICAL_BOUNDARIES/CCAzip.pdf. Both ZIP Codes and Community Areas are also geographic datasets on this data portal.

COVID-19 vaccinations administered to Chicago residents, by home ZIP Code of the person vaccinated. The vaccinations did not necessarily take place in the same ZIP Code. Daily counts are shown for each of the two doses required for full compliance with the vaccination protocols, as well as cumulative totals as of that date.

All data are provisional and subject to change. Information is updated as additional details are received and it is, in fact, very common for recent dates to be incomplete and to be updated as time goes on. At any given time, this dataset reflects data currently known to CDPH.

Data Source:

COVID-19 vaccinations administered to Chicago residents based on the home Zip Code of the person vaccinated, as provided by the medical provider in Illinois Comprehensive Automated Immunization Registry Exchange (I-CARE). The Zip Code where a person lives is not necessarily the same Zip Code where the vaccine was administered. Daily counts are shown for the total number of doses administered, first doses only, and number of people who have completed the necessary doses to be considered fully vaccinated. Cumulative totals for each measure as of that date are also provided. Requirements to be considered fully vaccinated vary depending on the vaccine manufacturer. Initial vaccines require two doses of vaccine to be administered over a period of time specific to each vaccine brand; future vaccines may only require one dose to be considered fully vaccinated. Vaccinations are counted based on the day the vaccine was administered.

Coverage percentages are calculated based on cumulative doses administered and cumulative number of people considered fully vaccinated in each Zip Code.

Population counts are from the U.S. Census Bureau American Community Survey 2015-2019 5-year estimates and can be seen in the Zip Code, 2019 rows of the Chicago Population Counts dataset (https://data.cityofchicago.org/d/85cm-7uqa).

All data are provisional and subject to change. Information is updated as additional details are received and it is, in fact, very common for recent dates to be incomplete and to be updated as time goes on. At any given time, this dataset reflects data currently known to CDPH.

Numbers in this dataset may differ from other public sources due to when data are reported and how City of Chicago boundaries are defined.
