Tactical Response Reports: Map and Census Data

What will you find here? 

To understand which communities may be impacted more by the Chicago Police Department’s (CPD) use of force than others, this dashboard compares the number of incidents resulting in a Tactical Response Reports (TRR)to the population of each CPD district. This interactive map also presents the demographic breakdown of TRRs and residents in each district. Users can toggle through years and data by incidents and population. 

Some questions that can be answered using data in this dashboard are: 

• What is the total number of TRR incidents compared to the total population? 
• Which districts are subject to higher rates of physical response by CPD members? 
• How has the total number of incidents by district changed over time? 

Data Sources 

All information presented in these dashboards is based on data stored in CPD databases and Chicago Integrated Personnel and Payroll Systems (CHIPPS), the City’s human resources information system. Records begin January 1, 2015, and the data is typically refreshed weekly on Sundays. Data represents the information that is in the CPD databases as of the date of last update (listed in the top right corner of the dashboards). TRRs provide details of incidents as reported by CPD members. The information in these dashboards only includes data from completed TRRs that indicate an individual was involved as a subject and that have a status of Approved, Submitted, or Preliminary. Incidents with multiple TRRs are identified by matching CPD Records Division (RD) Numbers, incident locations, and incident times across TRRs. Population data is from US Census Bureau 2017-2021 American Community Survey estimates and is aggregated by geographic area based on each area’s geographic intersection with census tracts.
