Context
How CrimeAtlas is organized
Additional reading notes to help interpret the statistics on this page.
Chicago crime-type pages currently cover categories such as homicide, each linked from the same underlying yearly and monthly aggregates.
Community area pages are linked directly from the homepage so local trend context remains crawlable and tied to the same aggregate refresh cycle as the city overview.
Year pages currently span 2001 through 2026, making it possible to compare calendar-year totals without recalculating the raw incident table on each request.

Credibility
Official sources and clear attribution
CrimeAtlas cites the source portal, dataset IDs, publishers, and latest import dates so pages can be traced back to the underlying public records.
The current Chicago build relies on official open datasets published by the City of Chicago, including the main incidents feed and geography reference datasets used for community area pages.
Source notes stay visible because public-records data can lag, be revised later, or use classifications that differ from how residents describe local conditions.
