Other Offense in Chicago — Crime Statistics 2026

A residual IUCR bucket, not a crime wave

CPD's IUCR list includes a primary type labeled Other Offense for reports that do not land in theft, battery, narcotics, or the other named types on this site. Telephone threats, violation of orders of protection, and miscellaneous ordinance-adjacent events can appear here when that is how the report was coded. The 28,178 figure is the size of that leftover category in the extract, not evidence that 28,178 identical crimes occurred.

Researchers who chart "top crimes" sometimes drop Other Offense because the label is opaque. That choice should be explicit. Omitting 28,178 rows from a 410,083-incident city total changes every remaining share. Including them without explaining the residual nature implies a single offense that IUCR does not define that way.

Researchers who inherit a spreadsheet of Chicago incidents should leave Other Offense visible until they have a documented recode. Silent deletion of 28,178 rows from 410,083 city incidents is a methodological choice, not a default. If a grant report needs "Part I" style groups, say that IUCR Other Offense was excluded and that the remaining shares no longer sum to the city extract.

How large the residual is

At about 6.9 percent of 410,083 Chicago incidents, Other Offense is a large residual. Volume does not mean homogeneity. Two rows in this type can describe unrelated statutes. The incident table's IUCR code and description fields are the only honest way to see what CPD wrote.

This page does not invent a ranking of those codes because the packet facts give one primary-type count. If you need a specific statute, filter the live table and keep CPD's wording. LocalCrimeVault will not relabel Other Offense as harassment, ordinance violation, or any other name.

Telephone-threat, violation-of-order, and miscellaneous codes can share this primary type. Two adjacent rows on the overlay can describe unrelated statutes. That is why this page refuses a single-behavior headline. The 28,178 figure is a bucket size, not a crime wave with one motive.

Questions

What is Other Offense in Chicago police data?

Other Offense is a CPD IUCR primary type for incidents that are not filed under a more specific named type on the public feed. This extract contains 28,178 such Chicago rows, about 6.9 percent of 410,083 city incidents. It is a residual label, not one behavior. LocalCrimeVault does not reclassify CPD charges.

Should I exclude Other Offense from crime charts?

Only if you say so. Dropping 28,178 rows from 410,083 Chicago incidents changes every other type's share. Including them without a note implies a single crime IUCR does not define. The accurate approach is to keep the residual visible and read IUCR codes on the table for detail.

Does Other Offense mean convictions?

No. Like every type on LocalCrimeVault, these 28,178 rows are police reports from the city open-data portal. They can exist without arrest or prosecution. Do not treat the residual bucket as a court caseload or as a count of unique offenders. The 28,178 count is reports, not a single crime and not convictions.

Where do I see what each Other Offense row actually is?
