An Analysis of Robbery in Oklahoma Using Incident-Based Reporting Data (SIBRS)

By Kara Miller, Monique Mogilka,

The Oklahoma Statistical Analysis Center (SAC) is co-located with the state’s criminal history repository, the state’s Uniform Crime Reporting (UCR) Program, and the State Incident Based Reporting (SIBRS) Program. The purpose for studying robbery in Oklahoma is to increase access to and understanding of National Incident-Based Reporting System (NIBRS) enhanced data. By analyzing NIBRS compatible data, the SAC strives to demonstrate the value SIBRS data can have for local agencies and government planners, as well as its utility for problem solving and understanding larger aspects of crimes reported in Oklahoma. The SAC and the Oklahoma State Bureau of Investigation (OSBI) demonstrate the value and utility of SIBRS data to encourage all local law enforcement agencies (LEAs) in Oklahoma to commit to SIBRS reporting and to report quality data. Key Findings:    The number of robberies reported varied nearly every month during the year, although the overall trend was an increase in reports between January and August. The number of reported robberies then fluctuated significantly between August and November. During this time period, reported robberies: o decreased 41.0% from August to September, o Increased 95.7% from September to October, and o Decreased 42.2% from October to November. The majority of robbery victims did not know the offender, as 60.9% of Victim to Offender Relationships were classified as Not Known to Victim. 33.9% of robberies were at a residence, with 40.5% of residential robberies occurring between 21:00-03:00. 1  61.1% of arrestees were arrested “On-View”, and only 25.0% were armed.  Money was the most commonly reported property type stolen (26.3%). However, automobiles which accounted for only 3.9% of the types of property stolen, accounted for 38.8% of the total value of stolen property.
