Homicide reports in Chicago

CPD incident rows, not a death-certificate file

Homicide on the open-data crime extract is the primary type CPD assigned to an incident. Cook County medical examiner records, FBI UCR homicide tables, and news tallies can differ because they use different rules, dates, and jurisdictions. This page quotes 797 CPD incident rows in the LocalCrimeVault harvest. It does not reconcile those other series.

Clearance, suspect age, and weapon detail may appear on some public homicide files. This packet facts object gives incidentCount 797 and cityIncidents 410083 only. No clearance rate or firearm share is stated here. If those fields exist on the table, they are CPD's, not invented subtotals.

News tallies often use a calendar year and a victim count. This page uses CPD incident rows: 797 among 410,083 indexed Chicago reports. If a row structure ever differs from one victim per row, read the table. This narrative does not invent a victim total separate from 797.

Share of the Chicago extract

Among 410,083 indexed Chicago incidents, 797 homicide rows are a small fraction. Most of the city feed is theft, battery, and other high-volume types. That arithmetic does not rank human loss. It only locates homicide inside the IUCR mix on this site.

Maps use block-level geography and official community area names (77 areas). Pins are not a named victim's address. This page will not list case names. Aggregate location and date are the public-record use.

Clearance is not a packet fact. Do not attach a clearance rate to 797. If a column on the overlay shows clearance, that value is CPD's published field, not a LocalCrimeVault calculation.

Reading the homicide table

Filter the 797 rows by date and community area. Treat each row as a CPD report as published. Do not assume one row equals one victim if the extract structure ever differs; read the table. Arrest or clearance flags, when present, are not convictions.

LocalCrimeVault does not add graphic description. Battery, robbery, and weapons violation are separate types in the same 410,083-row file. Do not fold them into 797.

Medical examiner death dates and CPD report dates can fall in different months. That is one reason series diverge. Quote the system. Official community area names are the 77-area list. Pins are not named victims. This page does not narrate individual deaths.

What 797 is not

It is not a conviction tally, not a sentencing tally, and not automatically equal to a calendar-year medical examiner homicide total. Date rules (incident date versus report date versus death date) differ across systems. Quote CPD IUCR primary type Homicide when you use 797.

CPD and the City of Chicago publish the incidents. LocalCrimeVault indexes them without reclassifying charges.

Chicago hub placement

The homicide type hub holds the live table for these 797 rows. The Chicago hub places homicide beside the rest of the 410,083-incident mix so the type is visible without crowding out larger IUCR categories. A cross-city homicide page follows other agencies' labels and year rules, which may not match this extract.

Cite 797 as Chicago Police Department incident rows with IUCR primary type Homicide among 410,083 city reports. Say which system you mean. Cook County medical examiner files, FBI tables, and news tallies can differ on dates, jurisdiction, and what counts as a homicide incident. This page does not reconcile those series.

Clearance, weapon, and victim-count fields may appear on some public homicide files. This packet facts object gives 797 and 410,083 only. No clearance rate is stated here. If a table column shows clearance, that value is CPD's, not an invented subtotal.

Citing CPD homicide rows without mixing death files

Do not fold battery, robbery, or weapons violation into 797. Those types have their own hubs in the same extract. This page will not list case names. Aggregate location and date are the public-record use.

Block-level geography and official community area names (77 areas) are not a named victim's address. Record the harvest. Date rules (incident versus report versus death) differ across systems. Quote CPD IUCR primary type Homicide when you use 797. LocalCrimeVault does not reclassify charges.

Questions

How many homicide reports are in the Chicago CPD index?

This extract lists 797 Chicago incidents with IUCR primary type Homicide, in a city file of 410,083 reports. The source is Chicago Police Department open data. The figure counts incident rows, not convictions and not automatically a medical examiner total. LocalCrimeVault does not reclassify CPD charges.

Is 797 the same as the medical examiner homicide count?

Not necessarily. Medical examiner files, FBI tables, and CPD incident extracts can differ on dates, jurisdiction, and what counts as a homicide incident. This page quotes 797 CPD rows in LocalCrimeVault's index of 410,083 Chicago reports. Cite the system you mean. This site does not reconcile other tallies.

Does a homicide row mean a conviction?

No. Public incident rows are reports. Investigations can continue for years. Clearance, if shown on a row, is not a guilty verdict. The 797 count is CPD report volume. Court outcomes live in other systems. This page does not narrate individual deaths. The 797 count is report volume among 410,083 city incidents, not convictions.

Are victim addresses shown on the map?

CPD's public extract uses block-level ranges and official community areas, not street-number addresses. Treat geography as coarse. Use the type table and Chicago hub for aggregate location as published. Do not treat a pin as identifying a household. The 797-row map uses CPD block ranges, not victim street-number addresses.
