Performance Metrics NIBRS Crime

Arlington has historically reported crime data using the Uniform Crime Report or ( UCR ) in Summary format . In 2017 , the Arlington Police Department transitioned from Summary format to the National Incident-Based Reporting System or NIBRS . While the department still publishes Summary UCR reports , the Police Department also began publishing NIBRS reports in 2018 . Texas DPS mandated all agencies to transition to NIBRS reporting by 2021 . Due to the distinct differences outlined below , it is important for the audience to know that the two cannot be compared to one another .
Summary Reporting System
Summary UCR consists of eight Part I Offenses which are divided into two categories : Violent and Property Crime . Violent Crime includes aggravated assault , forcible rape , murder , and robbery . Property Crime includes arson , burglary , larceny-theft and motor vehicle theft .
UCR Summary Facts :
• Provides monthly aggregate crime counts for eight index crimes called Part I Crime .
• Records crimes against persons and property .
• Records one offense per incident .
• Does not distinguish between attempted and completed crimes .
• Typically records the most serious offense in an incident ( known as the hierarchy rule ).
National Incident-Based Reporting System
NIBRS has 46 Group A Offenses compared to Summary UCR ’ s eight Part I Offenses . NIBRS is structured to improve the methodology used in compiling , analyzing , auditing , and publishing collected crime stats . Like Summary UCR , NIBRS reports crime against persons and crime against property . However , NIBRS has a third category , crime against society .
NIBRS Facts :
• Provides individual incident records for eight index crimes and 38 other offenses , which are called Group A Offenses .
• Records crimes against persons , property , and society .
• Records each offense occurring within an incident .
• Distinguishes between attempted and completed crimes .
• Does not use the hierarchy rule .
• Dynamic reporting , can change as case evolves .
