City of Concord 2022 Crime Statistics

The following table provides a summary of crimes in the City of Concord for the calendar year. More detailed offense reporting is also available on this page.

Changes in Crime Reporting

Since its earliest days, the Federal Bureau of Investigation (FBI) has collected national crime data.

Before 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. On January 1, 2021 the National Incident-Based Reporting System (NIBRS) replaced UCR as the nationwide data collection method. The implementation of NIBRS will provide consistency in crime reporting across the United States. In addition, it will support law enforcement’s ability to report reliable information to optimize law enforcement management, training, planning, and research to strategically and effectively reduce crime.

Differences between UCR and NIBRS

It is essential to highlight the differences between UCR and NIBRS, as the Concord Police Department’s crime statistics will change due to this new reporting method.

UCR

• Consists of monthly aggregate crime count for 8 Index crimes
• Records one offense per incident as determined by the hierarchy rule
• The hierarchy rule suppresses counts of lesser offenses in multiple-offense incidents
• It 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 the definition of assault
• Collects weapon information for all violent offenses

NIBRS can produce more detailed, accurate, and meaningful data because it collects data on when and where crime takes place, what form it takes, and the characteristics of its victims and perpetrators.

NIBRS Crime Categories and Offenses

Concord Police Department’s Transition to NIBRS

The Concord Police Department (CPD) transition to a new Computer Aided Dispatch (CAD) and Records Management System (RMS) on December 15, 2020, to facilitate the transition to NIBRS.

CPD began submitting NIBRS data to the California Department of Justice in February 2021. 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.

Result of the Change from UCR to NIBRS

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 Concord’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 are reported.

Examples of how crime is reported under UCR and NIBRS

NIBRS crime data are electronically reported after the last day of each month. The NIBRS data is collected from the offenses and associated details contained in a police report; therefore, the NIBRS data is only submitted once 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. 

Reporting to NIBRS Workflow

 *** To provide crime statistic data to the public as expeditiously as possible, the crime statistics 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 statistics for police reports submitted to NIBRS are tallied based on the date of incident occurrence. For example, if a crime is reported to CPD 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 and NIBRS until the end of the March submission period. Once the March NIBRS submission is accepted, the crime statistic data from January will be adjusted to include the newly submitted offenses. Thus, NIBRS crime 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 Records and NIBRS.
