All drivers reported by Transportation Network Providers (sometimes called rideshare companies) to the City of Chicago as part of the licensing process and routine reporting required by ordinance. Inclusion of a driver in a monthly report indicates that the driver was eligible for trips in Chicago in that month for at least one day, regardless of whether he or she actually provided any rides. If a driver is eligible in multiple months, which is common, he or she will have records in each of these reporting months.

As of the creation of this dataset, there have been four TNPs licensed to operate in Chicago, although never more than three at any given time and currently three. Drivers reported by more than one company in the same month are combined and the MULTIPLE_TNPS column is marked as TRUE. However, the matching process is imperfect so not all such drivers are necessarily identified. Similarly, matching between the licensing and routine reporting databases is imperfect, creating potential for occasional errors.

The reporting is done on a monthly basis, as indicated in the MONTH_REPORTED column. However, starting in 2018, the reports are batched and files for all three months in a quarter are delivered to the City of Chicago at the end of each quarter. Due to an issue in this transition, some vehicle records for Q2 2018 (April-June) were reported for the quarter as a whole, rather than for individual months. For purposes of this dataset, those records have been assigned to 2018-06 (June). Therefore, some caution in interpreting this month and the quarter as a whole is advised.

Taxi trips reported to the City of Chicago in its role as a regulatory agency. To protect privacy but allow for aggregate analyses, the Taxi ID is consistent for any given taxi medallion number but does not show the number, Census Tracts are suppressed in some cases, and times are rounded to the nearest 15 minutes.

Due to the data reporting process, not all trips are reported but the City believes that most are.

In order to help contractors and private residents avoid existing utility lines (including gas, electrical, and water lines) when digging, the Chicago Department of Transportation maintains 811 Chicago, a free, 24-hour service to private contractors and homeowners in Chicago. Anyone planning to dig within Chicago must obtain a “dig ticket” from 811 Chicago. 811 Chicago notifies all utilities of the impending excavations. The utility owners then send out staff to mark the location of the underground facilities within 48 hours (excluding emergencies), not counting Saturdays, Sundays, and holidays.

This dataset shows these utility notifications. Since it is common for the same dig ticket to produce multiple notifications, the same dig ticket will appear multiple times and this dataset cannot be used without further refinement to count, map, or analyze unique excavations in Chicago.

See https://ipi.cityofchicago.org/Digger for more information on the dig ticket system.

Traffic fatalities within the City of Chicago that are included in Vision Zero Chicago (VZC) statistics. Vision Zero is Chicago’s commitment to eliminating fatalities and serious injuries from traffic crashes. The VZC Traffic Fatality List is compiled by the City’s multi-departmental Fatal Crash Response Coordination Committee (FCRCC) that reviews fatal traffic crashes provided by Chicago Police Department’s Major Accident Investigation Unit (MAIU). The dataset is updated after the FCRCC meetings in the 4th week of the month. Thus, the fatality list for a particular month will be available in the dataset after the 4th week of the following month.

This committee uses a standardized process – sometimes differing from other sources and everyday use of the term -- to determine whether a death is a “traffic fatality” for VZC purposes. Therefore, the traffic fatalities included in this list may differ from the fatal crashes reported in the full Traffic Crashes dataset (https://data.cityofchicago.org/d/85ca-t3if).

Official traffic crash data are published by the Illinois Department of Transportation (IDOT) on a yearly basis. The traffic fatality list determined on an ongoing basis through the year may differ from IDOT’s official crash data for Chicago as IDOT may define the cause and location differently from the FCRCC. Once IDOT publishes its data for a year, crashes in this dataset for that year are edited to match IDOT’s determinations, unless the FCRCC disagrees with the IDOT determination – which happens only rarely and usually due to an interpretation of one of the criteria below.

VZC Traffic Fatalities can be linked with other traffic crash datasets using the “RD_NO” or “Person_ID” fields.

The FCRCC defines a “traffic fatality” for the purpose of VZC statistics as "any death caused by a traffic crash, within 30 days of the crash” and “involves a motor vehicle.” Fatalities that meet the VZC definition of a traffic fatality are included in this dataset unless excluded by the criteria below. There may be records in this dataset that do not appear as fatalities in the other datasets.

The following criteria exclude a death from being considered a "traffic fatality" for VZC purposes:

1. The Medical Examiner determined that the primary cause of the fatality was not the traffic crash, including:

a. The fatality was reported as a suicide based on a police investigation.

b. The fatality was reported as a homicide in which the "party at fault" intentionally inflicted serious bodily harm that caused the victim's death.

c. The fatality was caused directly and exclusively by a medical condition or where the fatality was not attributable to road user movement on a public roadway. (Note: If a person driving suffers a medical emergency and consequently hit and kills another road user, the other road user is included although the driver suffering a medical emergency is excluded.)

2. The crash did not occur within the public right-of-way.

3. The crash involved a train or such mode of transport within their dedicated right-of-way.

4. The fatality was on a roadway not under Chicago Police Department jurisdiction, including:

a. The fatality was occurred on an expressway. The City of Chicago does not have oversight on the expressway system. However, a fatality on expressway ramps occurring within the City jurisdiction will be counted in Vision Zero Chicago Traffic Fatalities.

b. The fatality occurred outside City limits. Crashes on streets along the City boundary may be assigned to another jurisdiction after the investigation if it is determined that the crash started or substantially occurred on the side of the street that is outside the City limits. Jurisdiction of streets along the City boundary are split between City and neighboring jurisdictions along the street center line.

5. The fatality is not for a person (e.g., an animal).

All trips, starting January 2023, reported by Transportation Network Providers (sometimes called rideshare companies) to the City of Chicago as part of routine reporting required by ordinance. For earlier trips, see the link in the Featured Content section below. This version of the datasets contains three new columns, marked in their column descriptions.

Census Tracts are suppressed in some cases, and times are rounded to the nearest 15 minutes. Fares are rounded to the nearest $2.50 and tips are rounded to the nearest $1.00.
