Criminal Sexual Assault reports in Chicago

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.

Share of the Chicago extract

At 2,796 reports, this type is much smaller than theft or battery in the 410,083-incident index and remains one of the types readers search by name. Small share is not small harm. Statistical rank and human impact are different questions; only the rank is a packet fact here (about 0.7 percent of indexed city incidents).

Do not combine Criminal Sexual Assault with Sex Offense, Offense Involving Children, or Battery to build an unofficial "sex crime" total unless you list every type included. CPD's labels are the ones this site keeps.

If a prosecutor later files a different charge, the public incident row may still say Criminal Sexual Assault. The 2,796 total follows CPD's published primary type in this harvest. LocalCrimeVault does not reclassify charges from court dockets.

What 2,796 is not

It is not a hospital forensic-exam count, not a rape-crisis hotline count, and not a court caseload. Those systems overlap imperfectly with CPD reports. Quote the open-data primary type if your question is how many incident rows CPD labeled Criminal Sexual Assault.

CPD and the City of Chicago publish the incidents. LocalCrimeVault indexes IUCR primary types as filed. Survivors are not named here. The respectful use of the table is aggregate: date, community area, report volume.

Chicago hub placement

The criminal sexual assault type hub is the overlay for these 2,796 rows. The Chicago hub shows the type beside the rest of the 410,083-incident mix. A cross-city page follows other agencies' labels, which may use different statute names. Cite CPD when you quote 2,796.

Cite 2,796 as Chicago Police Department incident rows with IUCR primary type Criminal Sexual Assault among 410,083 city reports (about 0.7 percent). Keep Sex Offense on its own hub. LocalCrimeVault does not reclassify charges and does not add graphic case detail. Survivors are not named here.

Victimization surveys consistently find underreporting for this class of events. That literature is not a packet fact, and this page does not estimate a "true" total from 2,796. The honest open-data claim is 2,796 public rows. Some reports are later unfounded or recoded; some events never appear.

Citing a sensitive type at aggregate level only

Hospital forensic exams, rape-crisis hotlines, and court caseloads overlap imperfectly. They are not merged into 2,796. If your question is service volume, use those systems. If your question is how many incident rows CPD labeled Criminal Sexual Assault, 2,796 is the packet fact.

Geography must stay coarse. Block-level ranges and official community area names (77 areas) are privacy-preserving on purpose. Do not treat a pin as a household or workplace. Record the 2,796 / 410,083 harvest pair. The overlay table is for aggregate date and area, not for reconstructing events.

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.
