Frequently asked questions

What does this Cook County crime map show?
It shows 37,715 public-safety calls-for-service recorded by the responsible law-enforcement agency in Cook County. Each call records that an officer was dispatched to a location — not that a crime was confirmed.
Are these confirmed crimes?
No. A call-for-service is a dispatch record. Many calls resolve as unfounded, civil matters, or routine community contact. Only an investigation and prosecution determines whether a crime occurred.
When is Cook County busiest for police calls?
In the current snapshot, the busiest hour is around 20:00 with 2,148 dispatches recorded in that hour. The 22:00–06:00 overnight window accounts for 8,414 calls.
What types of incidents are most common in Cook County?
In the current snapshot the three most frequent types are battery — domestic battery simple, battery — simple, assault — simple. These are not necessarily the most serious — most calls are service or traffic-related, and our category bar lets you filter by violent, property, medical, traffic, disorder, drugs, suspicious, or service.
How often is the data updated?
We re-ingest each upstream refresh and republish here within minutes. The exact cadence depends on the originating agency.
Where does the data come from?
From the public open-data feeds of the relevant US law-enforcement agencies. Each place page credits its source.
Does this map show names of people involved?
No. Even if the upstream feed includes names, we strip them on ingest and never display them. We never republish booking photos. If you need verified record information, contact the originating agency.
Is Cook County a safe place to live?
That question depends on far more than dispatch counts — neighbourhoods within the same county can vary widely, and call volume reflects police activity as much as underlying conditions. Use this map as one signal among many, alongside Illinois and statewide statistics, local news, and direct agency contact. We do not characterise places as "safe" or "dangerous".
Can I get an alert when a call happens at my address?
Saved-address alerts are coming with our Pro plan. Until then, this page will always update automatically when the upstream feed refreshes.
How do I request a correction or removal?
Use our correction request page. The originating agency remains the system of record — if the agency corrects or suppresses a record at the source, our next ingestion reflects the change automatically.
