This request for what is traditionally called calls for service data covers the year 2020. This data is generated every time someone calls 911 seeking police services. The Office of Emergency Management and Communications (OEMC) receives these calls and generates the data.
We have been engaged with the Office of Emergency Management & Communications (OEMC) since 2016 trying to open their data. Our data warehouse now has meta data on calls for service dating back to 1999.. We won access to this data through a settlement with OEMC in Cook County Circuit Court.
We have obtained data on millions of additional calls for police service from the Chicago Police Department who maintains historical data from OEMC dating back to 1999. We are still fighting the CPD in court as the amount of calls turned over to us in the 18 years we requested from them has ranged from as little as 13% of what is listed in their annual report to almost 190% of what was listed. Much work remains to get a cohesive and legitimate data set from the CPD.
