Data Description: Emergency Communications Center Calls are records captured for each call. The call data does not contain the nature of the emergency or dispatched resources. For dispatch data reference Police Calls for Service (CAD) or Cincinnati Fire Incidents (CAD).

Data Creation: This dataset includes both emergency (911) and administrative calls to the center. To obtain just emergency (911) calls filter for Call Type = 911.

Data Created By: The source of this data is the City of Cincinnati's Call System that was provided by Cincinnati Bell.

Refresh Frequency: This dataset contains calls from January 1, 2013 through December 14, 2017. On December 14, 2017 the Emergency Call Center transferred to a new phone system and the remainder of 2017 was captured in that system. Additionally, for a portion of 2014, around May, operations were temporarily transferred to the back-up location and call records were not captured.

Data Dictionary: A data dictionary providing definitions of columns and attributes is available as an attachment to this dataset.

In that pursuit the Office of Performance and Data Analytics facilitates standard processing to most raw data prior to publication. Processing includes but is not limited: address verification, geocoding, decoding attributes, and addition of administrative areas (i.e. Census, neighborhoods, police districts, etc.).

Disclaimer: In compliance with privacy laws, all Public Safety datasets are anonymized and appropriately redacted prior to publication on the City of Cincinnati’s Open Data Portal. This means that for all public safety datasets: (1) the last two digits of all addresses have been replaced with “XX,” and in cases where there is a single digit street address, the entire address number is replaced with "X"; and (2) Latitude and Longitude have been randomly skewed to represent values within the same block area (but not the exact location) of the incident.
