Municipal and State code violation notices issued by the Department of Environment (DOE) from January, 1993 to December 31, 2012 and by the Department of Public Health (CDPH) Permitting and Inspections unit since January 1, 2012. On January 1, 2012, the DOE was disbanded and all its inspection, permitting, and enforcement authorities were transferred to the CDPH.
Data fields requiring description are detailed below.
MAPPED LOCATION: Contains latitude/longitude coordinates of the site as determined through the Chicago Open Data Portal’s geocoding engine. In instances where the facility address is a range, the lower number (the value in the “Street Number From” column) is used for geocoding. For example, for the range address 1000-1005 S Wabash Ave, the Mapped Location would be the coordinates for 1000 S Wabash Ave.
DOCKET NO: This the unique identifier assigned to the case. A docket number can contain multiple tickets.
TICKET NO: This is the unique identifier of the issued ticket. A ticket can contain up to two code violations. NOTE that the Department of Environment Ticket No.’s may refer to non-unique violations.
RESPONDENT: The name of the entity issued the code violation notice.
CASE TYPE: The Case Types are historic 3-Day Notice, Air Pollution Defect Notice, Administrative Hearing, Summary Abatement, Chicago Storage Tank NOV, State Administrative Citation, State Violation Notice, historic Pre Enforcement Conference, and historic Ticket-Municipal Prosecution.
VIOLATION DATE: The date of the code violation.
CODE VIOLATION: This refers to the municipal or state code violation being cited in the ticket.
DISPOSITION: The outcome of the code violation.
CASE STATUS: This refers to the final or most current status of the case.
FINE AMOUNT: This is the total fine assessed for the case not including court fees. Note that for the Historic Department of Environment data, this value is not unique to the record but applies to the entire case. For example, the case with a Docket No of 07DE000171 has two records with a fine amount of $350 in each record. The total fine on the case is $350, not the sum of $700.
COMMENT: Additional information relating to the violation or case.
DATA SOURCE: The city department that collected the data.

This dataset contains counts of people tested for COVID-19 and their results. This dataset differs from https://data.cityofchicago.org/d/gkdw-2tgv in that each person is in this dataset only once, even if tested multiple times. In the other dataset, each test is counted, even if multiple tests are performed on the same person, although a person should not appear in that dataset more than once on the same day unless he/she had both a positive and not-positive test.

Only Chicago residents are included based on the home address as provided by the medical provider.

Molecular (PCR) and antigen tests are included, and only one test is counted for each individual. Tests are counted on the day the specimen was collected. A small number of tests collected prior to 3/1/2020 are not included in the table.

Not-positive lab results include negative results, invalid results, and tests not performed due to improper collection. Chicago Department of Public Health (CDPH) does not receive all not-positive results.

Demographic data are more complete for those who test positive; care should be taken when calculating percentage positivity among demographic groups.

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