A sensitive IUCR type, counted as reports
Criminal Sexual Assault on the CPD extract is the primary type CPD assigned when the report was written. Sex Offense is a separate IUCR primary type on the same city feed; the two should not be added together without saying so. The 2,796 figure is a row count. It is not a count of unique survivors, unique suspects, or prosecuted cases.
Sexual assault is widely underreported in victimization research. That research is not a packet fact, and this page does not invent an "true total." The honest statistic is 2,796 public CPD incident rows among 410,083 indexed Chicago reports. Many events never appear in police files; some reports are later unfounded or recoded.
Sex Offense is a separate hub. Do not add that type to 2,796 without listing both labels. Among 410,083 Chicago incidents, Criminal Sexual Assault is about 0.7 percent. Small share is not small harm; only the report count is a packet fact.
How to read the public table respectfully
The type hub lists reports with the fields CPD shares: date, block-level location, community area, and related attributes. Block ranges are not street-number addresses of survivors. Official community area names are the city's 77-area geography. Do not treat a pin as identifying a household or a workplace.
Description fields on open-data crime files can be sparse by design. This page will not reconstruct events. If a row includes an arrest flag, that flag is still not a conviction. Missing geography is left blank. LocalCrimeVault does not impute a community area.
Public description fields are often sparse by design. This page will not reconstruct events from those fields. The overlay is for date, official community area, and report volume. Survivors are not named. Block ranges are not street-number addresses.

Questions
- How many criminal sexual assault reports are in Chicago CPD data?
- This extract lists 2,796 Chicago incidents with IUCR primary type Criminal Sexual Assault, about 0.7 percent of 410,083 city reports. The source is Chicago Police Department open data. The figure counts police reports, not convictions, unique people, or a victim survey. LocalCrimeVault does not reclassify CPD charges.
- Is criminal sexual assault the same as sex offense in this data?
- No. CPD files Criminal Sexual Assault and Sex Offense as separate IUCR primary types. This page covers only the 2,796 criminal sexual assault rows. Adding the types without disclosure mixes official labels. Use each type hub if you need both series. Keep 2,796 separate from the Sex Offense type hub.
- Does a report mean a conviction?
- No. Public incident rows are reports. They can exist without an arrest, after a case is declined, or if a report is later updated. The 2,796 count is report volume among 410,083 indexed Chicago incidents. Court outcomes live in other systems. This page does not describe individual cases.
- Are survivor addresses shown on the map?
- CPD's public extract uses block-level ranges and official community areas, not street-number addresses of survivors. Treat geography as coarse on purpose. The type table and Chicago hub should be used for aggregate report location as published, not to identify people. The 2,796-row map uses CPD block ranges, not survivor street addresses.
Offense types are CPD IUCR primary categories on the public incident feed. LocalCrimeVault does not reclassify charges.

What is criminal sexual assault in Chicago?
Criminal sexual assault is sexual penetration accomplished by force, threat of force, or against a victim unable to give knowing consent. Under Illinois law (720 ILCS 5/11-1.20) it is a Class 1 felony, rising to aggravated criminal sexual assault — with weapons, bodily harm, or other aggravating factors — a Class X felony. Illinois abolished its statute of limitations for major sex crimes in 2017.
Chicago PD files these under criminal-sexual-assault IUCR codes, split into non-aggravated and aggravated descriptions with the means of force noted. Reporting is victim-initiated and the category is widely understood to undercount actual incidence.
LocalCrimeVault has 3,105 criminal sexual assault reports indexed in Chicago — 0.7% of all tracked incidents. The most recent full month on record (August 2026) logged 25 reports, down from 130 in July 2026.
