Sex Offense in Chicago — Crime Statistics 2026

A separate IUCR type from criminal sexual assault

CPD files Sex Offense and Criminal Sexual Assault as two primary types. Combining them into an unofficial total without listing both labels will confuse anyone comparing to CPD's own tables. This page is only the 2,148 Sex Offense rows. The other type has its own hub and its own count (not repeated here as a second headline because it is not in this packet's facts beyond the shared city total of 410,083).

Underlying IUCR codes inside Sex Offense vary. This narrative does not invent those subtotals. Use the table's code and description fields. Public extracts often keep descriptions short.

Criminal Sexual Assault has its own count on its own hub. This page's 2,148 rows are only Sex Offense among 410,083 Chicago incidents (about 0.5 percent). Combining them without disclosure mixes official CPD labels.

Cite 2,148 with the 410,083 Chicago incident denominator (about 0.5 percent). Keep the IUCR name Sex Offense in the citation so it is not confused with Criminal Sexual Assault. The overlay table is the place for code-level detail. Geography stays block-level. LocalCrimeVault does not reclassify charges.

Share of the Chicago index

At 2,148 reports, Sex Offense is about 0.5 percent of 410,083 indexed Chicago incidents. It is a small share of the city feed and still a type people look up by name. Rank order is a packet fact; severity ranking is not.

Block-level geography and official community area names apply. Pins are not street-number addresses of victims or accused persons. Do not treat a map cluster as identifying a household.

Public extracts often keep descriptions short. That is a privacy and records practice, not missing analysis. This narrative does not fill those descriptions. Filter IUCR codes on the 2,148-row table if you need a narrower statute cut.

If a later harvest recodes rows, 2,148 can move. Record the extract. Public description fields are often short on purpose. This page will not expand them. Official community area names are the city's 77 areas. An arrest flag is not a conviction.
