Memo ID# 2023100
This memorandum provides City Council with information related to the California Incident-
Based Reporting System (CIBRS) which will be used to collect and report crime data.
Background
The Federal Bureau of Investigation (FBI) has used the Uniform Crime Reporting (UCR) system
to collect crime data since it was created in 1929. In 1989, the National Incident-Based
Reporting System (NIBRS) was developed to create a more accurate method of collecting crime
data about victims, offenders, property, and arrests.
In January 2021, NIBRS became the FBl's national standard for law enforcement crime data
reporting in the United States. Because California has several crime classifications that are not
federally recognized, the California Department of Justice (CA DOJ) created the CIBRS for
California agencies.
The Automated Regional Justice Information System (ARJIS) transmits crime data to the CA DOJ
for local law enforcement agencies in San Diego County. ARJIS began transmitting CIBRS data
to the CA DOJ in 2021 while simultaneously collecting UCR data for statistical comparison. As of
December 31, 2023, ARJIS will no longer collect UCR data, and the San Diego Association of
Governments (SAN DAG) will only release annual and mid-year crime rate reports using CIBRS
data. As a result, the Carlsbad Police Department will only collect and report data using the
CIBRS crime classifications.
Discussion
The benefits of collecting CIBRS data include:
• Collecting more accurate data
• Arrests and clearances are linked to specific incidents
• Addition of crimes against society
• Documents animal cruelty, extortion, and identity theft offenses

• Gives context to crimes, including the relationship between victims and offenders, types
and quantities of drugs involved, and types of property that were damaged or stolen
• Provides greater analytical flexibility
Key Differences
CIBRS
22 crime classifications and 58 offenses reported : 8 crime classifications reported
Up to 10 offenses per incident are reported i Employs a hierarchy rule and only reports the
I highest offense
Date of offense is reported (statistics are counted i Date of report taken is reported (statistics are
I
in the month of the incident); crime rates will ' counted in the month the report was taken and
change as crimes are reported uploaded); crime rates are static
Sprees counted as one incident I One crime report for each victim in a spree
Co-conspirators: Offenders must admit to Co-conspirators: All offenders were assumed to
knowingly participate in each event . have knowledge of each event --
Auto theft: Commercial victims are not counted; Auto theft: All victims of auto theft are included
embezzled vehicles from commercial victims are
counted as fraud or embezzlement. Attempted
thefts are not counted

dangerous weapon or great bodily injury; all 1 weapons and intimidation

*Group B: Reported only if an arrest is made *Part II: Reported even if no arrest was made _
*The below referenced Attachment shows the different classifications of crimes under both
CIBRS and UCR.
Impact on Crime Statistics
• The crime index report using CIBRS data will look much different than what was previously
reported using UCR.
• Possible increases in crime rates due, in part, to the elimination of the hierarchy rule and the
allowance of reporting up to 10 offenses in a single incident.
• Possible decreases in crime rates due, in part, to the change in definition of victims for certain
crimes (i.e. auto theft) or separation of crime classification (i.e. sex offenses).
• Monthly crime statistics are expected to be more accurate because they are reported based
on the incident date, as compared to the report date.

Next Steps
The Police Department will produce crime index comparisons using CIBRS. There is minimal
impact on daily police operations.
