Assault in Chicago — Crime Statistics 2026

Assault versus battery on IUCR rows

CPD's public extract uses Assault for threat or attempt events that are not filed as Battery. Battery is the contact/harm primary type; assault is the threat-or-attempt primary type as CPD applied IUCR on the report. Readers who collapse "assault and battery" into one phrase will overstate either table. This page is only the 37,107 assault rows.

Aggravated versus simple distinctions, when they exist, appear in IUCR codes or descriptions on the incident table. The packet facts supply a single primary-type count, so this narrative does not invent an aggravated subtotal. Weapons, injury, and relationship fields belong on the row if CPD published them. They are not inferred here.

Volume in the 410,083-incident extract

At 37,107 reports, about 9.0 percent of indexed Chicago incidents carry IUCR primary type Assault. That share describes the feed of 410,083 reports, not the share of all threats that occurred in the city. Unreported events never enter the 37,107. The type is still large enough to appear on almost any city-wide chart of this extract.

Person-crime maps attract more attention than property maps. The same privacy rules apply: block-level locations, official community area names, no street-number victim addresses. A dense cluster of assault reports can reflect nightlife, transit, schools, or household calls. The table does not assign a cause.

Questions

How many assault reports are in the Chicago CPD extract?

This index includes 37,107 Chicago incidents with primary type Assault, about 9.0 percent of 410,083 city reports. Source: Chicago Police Department incidents on the city open-data portal. The total counts police reports, not convictions or unique people. LocalCrimeVault does not reclassify CPD charges. Assault is 37,107 of 410,083 indexed Chicago incidents in this harvest.

Is Chicago assault the same as battery?

No. CPD files Assault and Battery as different IUCR primary types. Assault on this page is the 37,107 rows labeled Assault. Battery is a separate type for completed contact or harm as CPD coded it. Combining them without saying so mixes two official labels and inflates either series.

Does an assault incident mean a felony conviction?

No. Public incident rows are reports. They can remain on the open-data feed without an arrest or after charges are not filed. The 37,107 count is report volume. Court case numbers and verdicts are not what this page totals. Read the table as CPD's published labeling of events.

Where should I compare assault to other Chicago crime types?

Use the Chicago hub to see assault next to the other types that make up 410,083 indexed city incidents. The assault type hub holds the row-level table. Cross-city assault pages use other agencies' feeds and may not follow IUCR. Always name CPD as the Chicago source.
