All lobbyist registration fillings submitted to the Board of Ethics during the 2010 reporting period. / All lobbyists must register with the City of Chicago Board of Ethics by filing a Statement of Registration within five business days of engaging in lobbying activity and annually thereafter by January 20th.
Lobbyist registration information is submitted to the Board of Ethics in paper form and is available in its entirety in the Board's offices. The Board has, since 2000, compiled and posted static lists of all lobbyists and their clients online. Data for the 2010 reporting period is limited because previous policy did not require the Board of Ethics to prioritize the reporting of all data available from paper filings.
Moving forward, the Board of Ethics will compile and report more data about lobbyists and their activities, and make that additional information publicly available in machine-readable format. /

Taxi trips from 2013 to 2023 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.

NOTE: This dataset has been retired and marked as historical-only.

Only Chicago residents are included based on the home ZIP Code, as provided by the medical provider, or the address, as provided by the Cook County Medical Examiner.

Cases with a positive molecular (PCR) or antigen test are included in this dataset. Cases are counted on the date the test specimen was collected. Deaths are those occurring among cases based on the day of death. Hospitalizations are based on the date of first hospitalization. Only one hospitalization is counted for each case. Demographic data are based on what is reported by medical providers or collected by CDPH during follow-up investigation.

Because of the nature of data reporting to CDPH, hospitalizations will be blank for recent dates They will fill in on later updates when the data are received, although, as for cases and deaths, may continue to be updated as further data are received.

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 definitions of COVID-19-related cases, deaths, and hospitalizations, sources used, how cases, deaths and hospitalizations are associated to a specific date, and similar factors.

As described in https://data.cityofchicago.org/stories/s/311-Dataset-Changes-12-11-2018/d7nq-5g7t, the function of this dataset was replaced by https://data.cityofchicago.org/d/v6vf-nfxy. This dataset is historical-only.

All 311 calls for open and vacant buildings reported to the City of Chicago since January 1, 2010. The information is updated daily with the previous day's calls added to the records. The data set provides the date of the 311 service request and the unique Service Request # attached to each request. For each request, the following information (as reported by the 311 caller) is available: address location of building; whether building is vacant or occupied; whether the building is open or boarded; entry point if building is open; whether non-residents are occupying or using the building, if the building appears dangerous or hazardous and if the building is vacant due to a fire.

NOTE: This dataset has been retired and marked as historical-only.

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".

Cases with a positive molecular (PCR) or antigen test are included in this dataset. 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 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). PCR and antigen tests reported to Chicago Department of Public Health (CDPH) through electronic lab reporting are included. Electronic lab reporting has taken time to onboard and testing availability has shifted over time, so these counts are likely an underestimate 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.

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.

All open graffiti removal requests made to 311 and all requests completed since January 1, 2011. The Department of Streets & Sanitation's Graffiti Blasters crews offer a vandalism removal service to private property owners. Graffiti Blasters employ "blast" trucks that use baking soda under high water pressure to erase painted graffiti from brick, stone and other mineral surfaces. They also use paint trucks to cover graffiti on the remaining surfaces. Organizations and residents may report graffiti and request its removal.
311 sometimes receives duplicate requests for graffiti removal. Requests that have been labeled as Duplicates are in the same geographic area and have been entered into 311’s Customer Service Requests (CSR) system at around the same time as a previous request. Duplicate reports/requests are labeled as such in the Status field, as either "Open - Dup" or "Completed - Dup." Data is updated daily.

This dataset contains the historical estimated congestion for the 29 traffic regions, starting in approximately March 2018. Older records are in https://data.cityofchicago.org/d/emtn-qqdi. The most recent estimates for each segment are in https://data.cityofchicago.org/d/t2qc-9pjd.

The Chicago Traffic Tracker estimates traffic congestion on Chicago’s arterial streets (non-freeway streets) in real-time by continuously monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses. Two types of congestion estimates are produced every 10 minutes: 1) by Traffic Segments and 2) by Traffic Regions or Zones. Congestion estimates by traffic segments gives observed speed typically for one-half mile of a street in one direction of traffic. Traffic Segment level congestion is available for about 300 miles of principal arterials. Congestion by Traffic Region gives the average traffic condition for all arterial street segments within a region. A traffic region is comprised of two or three community areas with comparable traffic patterns. 29 regions are created to cover the entire city (except O’Hare airport area). There is much volatility in traffic segment speed. However, the congestion estimates for the traffic regions remain consistent for a relatively longer period. Most volatility in arterial speed comes from the very nature of the arterials themselves. Due to a myriad of factors, including but not limited to frequent intersections, traffic signals, transit movements, availability of alternative routes, crashes, short length of the segments, etc. Speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes. The segment speed and traffic region congestion estimates together may give a better understanding of the actual traffic conditions. Current estimates of traffic congestion by region are available at http://bit.ly/103beCf.

All open abandoned vehicle complaints made to 311 and all requests completed since January 1, 2011. A vehicle can be classified as abandoned if it meets one or more of the following criteria:All open abandoned vehicle complaints made to 311 and all requests completed since January 1, 2011.

A vehicle can be classified as abandoned if it meets one or more of the following criteria: 1) On a public way in a state of disrepair as to be incapable of being driven in its present condition. 2) Has not been moved or used for more than seven consecutive days and is apparently deserted. 3) Has been left on the public way without state registration or a temporary state registration placard for two or more days. 4) Is a hazardous dilapidated vehicle left in full view of the general public, whether on public or private property.

For some Open service requests, the vehicle has been towed but further action is required before the request may be closed. 311 sometimes receives duplicate abandoned vehicle complaints.

If a vehicle is towed it remains as open, work in progress until it is redeemed, transferred or disposed of. The service request is not closed until there is a final disposition for the vehicle.

Requests that have been labeled as Duplicates are in the same geographic area and have been entered into 311 Customer Service Requests (CSR) system at around the same time as a previous request.

All open and completed tree trim requests made to 311 since January 1, 2011. The Department of Streets and Sanitation maintains all trees growing in the public way and performs regular maintenance trimming in response to 311 requests. Crisis trimming is performed on an emergency basis in response to hazardous conditions such as broken or hanging branches. Requests that have been labeled as Duplicates are in the same geographic area and have been entered into 311’s Customer Service Requests (CSR) system at around the same time as a previous request. Duplicate requests are labeled as such in the Status field, as either "Open - Dup" or "Completed - Dup." Data is updated daily.

The Chicago Department of Transportation (CDOT) oversees the patching of potholes on over 4,000 miles of arterial and residential streets in Chicago. CDOT receives reports of potholes through the 311 call center and uses a computerized mapping and tracking system to identify pothole locations and efficiently schedule crews. One call to 311 can generate multiple pothole repairs. When a crew arrives to repair a 311 pothole, it fills all the other potholes within the block. Pothole repairs are generally completed within 7 days from the first report of a pothole to 311. Weather conditions, particularly frigid temps and precipitation, influence how long a repair takes. On days when weather is cooperative and there is no precipitation, crews can fill several thousand potholes.

If a previous request is already open for a buffer of 4 addresses the request is given the status of "Duplicate (Open)". For example, if there is an existing CSR for 6535 N Western and a new request is received for 6531 N Western (which is within four addresses of the original CSR) then the new request is given a status of "Duplicate (Open)".

Once the street is repaired, the status in CSR will read “Completed” for the original request and "Duplicate (Closed)" for any duplicate requests. A service request also receives the status of “Completed” when the reported address is inspected but no potholes are found or have already been filled. If another issue is found with the street, such as a “cave-in” or “failed utility cut”, then it is directed to the appropriate department or contractor.

This dataset is historical. For recent data, we recommend using https://chicagotraffictracker.com. -- Average Daily Traffic (ADT) counts are analogous to a census count of vehicles on city streets. These counts provide a close approximation to the actual number of vehicles passing through a given location on an average weekday. Since it is not possible to count every vehicle on every city street, sample counts are taken along larger streets to get an estimate of traffic on half-mile or one-mile street segments. ADT counts are used by city planners, transportation engineers, real-estate developers, marketers and many others for myriad planning and operational purposes.
Data Owner: Transportation.
Time Period: 2006.
Frequency: A citywide count is taken approximately every 10 years. A limited number of traffic counts will be taken and added to the list periodically.

All open reports of "Street Lights - All Out" (an outage of 3 or more lights) made to 311 and all requests completed since January 1, 2011.The Chicago Department of Transportation (CDOT) oversees approximately 250,000 street lights that illuminate arterial and residential streets in Chicago. CDOT performs repairs and bulb replacements in response to residents’ reports of street light outages.

Whenever CDOT receives a report of an “All Out” the electrician assigned to make the repair looks at all the lights in that circuit (each circuit has 8-16 lights) to make sure that they are all working properly. If a second request of lights out in the same circuit is made within four calendar days of the original request, the newest request is automatically given the status of “Duplicate (Open).” Since CDOT's electrician will be looking at all the lights in a circuit to verify that they are all working, any “Duplicate (Open)” address will automatically be observed and repaired.

Once the street lights are repaired, the status in CSR will read “Completed” for the original request and “Duplicate (Closed)” for any duplicate requests. A service request also receives the status of “Completed” when the reported lights are inspected but found to be in good repair and functioning; when the service request is for a non-existent address; or when the lights are maintained by a contractor. Data is updated daily.
