Tactical Response Reports: Levels of Force

What will you find here? 

This dashboard provides information on the subject actions which the Chicago Police Department (CPD) reports as having led to a use of force. Users can analyze the kind of subject actions correlated to specific outcomes and compare the severity of actions to the level of force reported by CPD members.  

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

• What percent of armed subjects were met with less than lethal force? 
• What is the most common level of force for subjects who are not under the influence of drugs or alcohol? 
• Which age range is subject to the highest level of force? 

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.
