Influenza Vaccination Coverage, Citywide

Chicago residents who are up to date with influenza vaccines, based on the reported address, race-ethnicity, sex, and age group of the person vaccinated, as provided by the medical provider in the Illinois Comprehensive Automated Immunization Registry Exchange (I-CARE).

“Up to date” refers to individuals aged 6 months and older who have received 1+ doses of influenza vaccine during the current season, defined as the beginning of July (MMWR week 27) through the end of the following June (MMWR week 26). 

Data Notes:

Weekly cumulative counts and coverage percentages of people up to date are shown for each combination of race-ethnicity, sex, and age group. Note that race-ethnicity, age, and sex all have an option for “All” so care should be taken when summing rows. Weeks begin on a Sunday and end on a Saturday. 

Coverage percentages are calculated based on the cumulative number of people in each race-ethnicity/age/sex population subgroup who are considered up to date as of the week ending date divided by the estimated number of people in that subgroup. Population counts are obtained from the 2020 U.S. Decennial Census. Actual counts may exceed population estimates and lead to coverage estimates that are greater than 100%, especially in smaller demographic groupings with smaller populations. Additionally, the medical provider may report incorrect demographic information for the person receiving the vaccination, which may lead to over- or underestimation of vaccination coverage. All coverage percentages are capped at 99%.

The Chicago Department of Public Health (CDPH) uses the most complete data available to estimate influenza vaccination coverage among Chicagoans, but there are several limitations that impact our estimates. Influenza vaccine administration is not required to be reported in Illinois, except for publicly funded vaccine (e.g., Vaccines for Children, Section 317). Individuals may receive vaccinations that are not recorded in I-CARE, such as those administered in another state, or those administered by a provider that does not submit data to I-CARE, causing underestimation of the number individuals who received an influenza vaccine for the current season. 

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.

Respiratory Virus Wastewater Surveillance

Concentrations of respiratory viruses in the Chicago sewer system as measured at seven sewershed sites since February 2022. In addition to SARS-CoV-2 (the virus that causes COVID-19), concentration data is also available for Respiratory Syncytial Virus (RSV), and influenza virus (types A and B). 

Generally, two samples are collected from each site during each week of the year. Concentration data reflect within-site and overall averages of this data each week. Because respiratory viruses are shed in human feces, tracking this data can help predict changes in disease trends and better understand the epidemiology of these common respiratory viruses in Chicago.

Please note that one of the "sites" listed is "All sites," which combines the individual sites. Care should be taken when summing or otherwise aggregating rows to avoid double counting.

These data are updated weekly and displayed on the Chicago Department of Public Health’s <a href="https://www.chicago.gov/city/en/depts/cdph/supp_info/infectious/respiratory-illness/respiratory-illness-data.html" target="_blank">Respiratory Illness Dashboard</a>.

Food Inspections

This information is derived from inspections of restaurants and other food establishments in Chicago from January 1, 2010 to the present. Inspections are performed by staff from the Chicago Department of Public Health’s Food Protection Program using a standardized procedure. The results of the inspection are inputted into a database, then reviewed and approved by a State of Illinois Licensed Environmental Health Practitioner (LEHP). For descriptions of the data elements included in this set, please click <a href="https://data.cityofchicago.org/api/assets/BAD5301B-681A-4202-9D25-51B2CAE672FF">here</a>.

Note about 7/1/2018 change to food inspection procedures that affects the data in this dataset: http://bit.ly/2yWd2JB

Disclaimer: Attempts have been made to minimize any and all duplicate inspection reports. However, the dataset may still contain such duplicates and the appropriate precautions should be exercised when viewing or analyzing these data. The result of the inspections (pass, pass with conditions or fail) as well as the violations noted are based on the findings identified and reported by the inspector at the time of the inspection, and may not reflect the findings noted at other times.

Chicago Traffic Tracker - Historical Congestion Estimates by Segment - 2024-Current

This dataset contains the historical estimated congestion for over 1,000 traffic segments, starting 6/11/2024 (except for a single time slice on 3/8/2024). Older records are in https://data.cityofchicago.org/d/sxs8-h27x.

The most recent estimate for each segment is in https://data.cityofchicago.org/d/n4j6-wkkf.

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.

Micro-Market Recovery Program - Permits

The City of Chicago launched the Micro-Market Recovery Program (MMRP), a coordinated effort among the City, not-for-profit intermediaries, and non-profit and for-profit capital sources to improve conditions, strengthen property values, and create environments supportive of private investment in targeted markets throughout the city. The goal of MMRP is to improve conditions, strengthen property values, and create environments supportive of private investment in targeted areas by strategically deploying public and private capital and other tools and resources in well-defined micro-markets.  This MMRP Permits dataset contains all Department of Buildings (DOB) Permits that have occured at properties falling within any MMRP Zone.  Permits, Cases and Violations can be linked to the MMRP Geographies dataset using ADDRKEY or ADDRGRPKEY.  To link Violations and Inspections to their Permits and Cases use Violation PERMITORCASEKEY to link to Permits APKEY_PERMIT and Cases APKEY_CASE.  For more information on the MMRP program, please see http://www.regionalhopi.org/content/city-chicago-micro-market-recovery-program-overview.

Bus Lanes - Local Streets

Bus lanes are travel lanes that are restricted to buses during certain hours of the day. All bus lanes have signs posted along the route with specific regulations; lanes marked "Bus Only" and /or painted red. Bus lanes help to keep buses from getting stuck in traffic, generally making travel for bus riders faster and reliable and improving the overall traffic flow of a corridor. Each record represents a segment of a bus lane based on the LION geographic base file of NYC streets. User may use the SegmentID field in this dataset to join with the LION data for more information.
