911 Calls by Geography

What will you find here? 

This dashboard allows users to visualize the concentration and frequency of dispatched 911 calls in different community areas, wards, and police districts. The information in these dashboards only includes service calls where a public safety unit was dispatched to the incident. Priority levels of calls are designated by 911 dispatchers at the OEMC. There are three main priority levels for calls resulting in a unit dispatch:

• Level 1: Immediate Dispatch for life-threatening emergencies
• Level 2: Rapid Dispatch for situations where timely public safety action has the potential to affect the outcome of an incident
• Level 3: Routine Dispatch when calls do not involve an immediate threat to life or bodily harm 

Some questions that this dataset can answer are: 

• What is the most common 911 call type?
• What types of calls are typically designated as a level 1 priority?
• Which district has the highest call rate?
