Crime Statistics, Calls for Service & Arrest Data

Important Changes in Crime Reporting

Since its earliest days, the Federal Bureau of Investigation (FBI) has collected national crime data.
Prior to 2021, California utilized the Summary Uniform Crime Reporting (UCR) method, often referred to as “Part I & PART II Crimes”, to report crime statistics to the FBI. In 2018, it was determined by the US Department of Justice that the National Incident Based Reporting System (NIBRS) would replace UCR as the nationwide data collection method effective January 1, 2021. The implementation of NIBRS is expected to provide consistency throughout the U.S. for quantifying crime. It will also support the mission to generate reliable information to optimize law enforcement management, training, planning and research to strategically and effectively reduce crime.

What are the Differences Between UCR and NIBRS?

It is important to highlight the differences between UCR and NIBRS, as the Antioch Police Department’s crime statistics will change as a result of this new reporting method.

UCR

  • Consists of monthly aggregate crime counts for 8 Index Crimes
  • Records one offense per incident as determined by hierarchy rule
  • Hierarchy rule suppresses counts of lesser offenses in multiple-offense incidents
  • Does not distinguish between attempted and completed crimes
  • Collects weapon information for murder, robbery, and aggravated assault
  • Provides counts on arrests for the 8 Index crimes and 21 other offenses

NIBRS

  • NIBRS collects data about victims, known offenders and relationships for offenses reported in 23 categories with 52 offenses. It also presents arrest data for those crimes, as well as 10 additional categories for which only arrest data is collected
  • Records each offense occurring in an incident
  • Distinguishes between attempted and completed crimes
  • Restructures definition of assault
  • Collects weapon information for all violent offenses

In short, NIBRS is capable of producing more detailed, accurate, and meaningful data because data is collected about when and where crime takes place, what form it takes, and the characteristics of its victims and perpetrators.

Current UCR Reporting vs NIBRS

Current UCR Reporting vs. NIBRS UCR NIBRS
Collects data on homicide, rape, robbery, aggravated assault, burglary, motor vehicle theft, larceny theft, and arson X X
Employs a Hierarchy Rule that only recognizes the most extreme crime within a particular incident X
Collects data on as many as 10 criminal offenses within a particular incident X
Collects incident and arrest data on 52 Group A offenses and arrest data on 10 Group B offenses X
Documents animal cruelty, extortion, and identity theft offenses X

When did the Transition to NIBRS Take Place?

The Antioch Police Department (APD) transitioned to a new Computer Aided Dispatch (CAD) and Records Management System (RMS) on December 1, 2021, to facilitate the transition to NIBRS.

APD began submitting NIBRS data to the California Department of Justice in February 2022. Once a NIBRS report is submitted to the DOJ, the data goes through an extensive compliance and validation process to check for errors such as incomplete or unfilled mandatory fields, ensuring proper coding of offenses, and reviewing high-level data accuracy. Law enforcement agencies are required to submit three (3) separate monthly crime report submissions, with a 4% or less margin of error, in order to achieve NIBRS certification. APD hopes to achieve certification by the Fall of 2022.

What Changes Should Residents Expect as a Result of this Change?

These changes will bring improved detail and a more transparent approach to crime reporting for the public. It will also make comparing crime statistics between communities more meaningful by ensuring consistency throughout the U.S. The availability of NIBRS data is also an opportunity for law enforcement to improve the way data is used to measure agency workload, outcomes and performance.

The perception may be that the City of Antioch’s lower-level crime statistics have increased. This change in reporting is not expected to reflect an actual increase in crime, but rather a change in the way crimes will be reported.

Examples of incidents of crime and how they are reported under each system:

Crime How the Item Would be Reported Under UCR How the Item Will be Reported in NIBRS
A bank robbery followed by a vehicle pursuit and a hit and run collision Robbery Robbery
Vehicle pursuit
Hit and run collision
A domestic violence incident in which a phone is vandalized and a purse is stolen Domestic Violence Domestic violence
Vandalism
Theft
A kidnapping followed by a vehicle theft Kidnapping Kidnapping
Vehicle theft

NIBRS crime data are electronically reported at the conclusion of the last day each month. The NIBRS data are collected from the offenses and associated details contained in a police report, therefore the NIBRS data is not submitted until the police report is completed and has gone through the audit and approval process. The progression from responding to an incident to submitting NIBRS data involves numerous steps and, depending on the extent of the investigation, can take a significant amount of time.

REPORT WRITING WORKFLOW

nibrs workflow 800

**To provide crime stat data to the public as expeditiously as possible, the crime stats presented on this page are based on UNAUDITED RMS data gathered from police reports throughout all steps of the report writing process and are therefore subject to change until Records Audit and NIBRS validation is complete.**

Crime stats for police reports submitted to NIBRS are tallied based on the date of incident occurrence. For example, if a crime was reported to APD in January, but the comprehensive investigation and report approval process did not conclude until March, the data would not be submitted to the CA DOJ/NIBRS until the end of March submission period. Once the March NIBRS submission is accepted, the crime stat data from January would be adjusted to include the newly submitted offense. Thus, NIBRS crime stat data is fluid and subject to change as additional NIBRS information is provided to the DOJ. The annual crime data is not static until all the police reports for the year have been audited, submitted, and validated by NIBRS.

This is Fascinating- Where can I Learn More?
