CCSO Joins FBI Data Collection Standard Via National Incident Reporting System (NIBRS) | |

CHARLES COUNTY, Maryland – In accordance with mandatory federal data collection standards, the Charles County Sheriff’s Office, along with police departments across the country, began implementing the FBI’s National Incident Reporting System (NIBRS). With a mandatory start date of January 1, 2021, law enforcement agencies nationwide have started to transition from the Summary Reporting System (SRS) to Unified Crime Reporting. (UCR) to the NIBRS, which offers significant improvements in the collection of statistical data, the classification of offenses, and the management of criminal incidents.

Although the UCR has served our country for many decades, the NIBRS is a more modern system with a number of advantages. The most important difference between the NIBRS and the traditional UCR system is the level of detail of the reports. NIBRS is more complete and detailed.

Unlike data reported through the UCR’s traditional SRS, which is an aggregated monthly crime tally and counts only one violation per incident, the NIBRS digs deeper into each incident to provide information on the circumstances and background of the crimes, such as the location, time of day and whether the incident has been resolved.

The NIBRS captures more details about victims, known offenders, victim-offender relationships, arrested persons, property and drugs involved in crimes. Additional detailed crime data is entered in a standardized format, which provides greater analytical capacity and makes NIBRS a more in-depth crime reporting standard.

The NIBRS counts 58 categories of offenses compared to the 10 categories of offenses collected by the DUC. The longer list includes offenses such as extortion and kidnapping, as well as many other common or serious offenses not included in the UCR.

Data submitted represents when an incident was reported to OHCC and does not include municipalities or Maryland State Police.
