Where these figures come from

Every figure on this page is read from the record file monthly_by_type.json, downloaded from the City of Chicago Open Data Portal and fetched on 2026-10-30. Period covered by these rows: each page covers one calendar month, December 2021 to December 2021.

All figures are counts of incident reports submitted to the Chicago Police Department. The arrest count is the number of those reports the same records flag as resulting in an arrest. These are reports, not proven offences, and an arrest is not a conviction.
