Using the Ohio Incident-based Reporting System (OIBRS), a modified version of the FBI's National Incident-based Reporting system, this analysis of Youngstown's 2009 crime data focuses on murder, robbery, aggravated assault, burglary, motor-vehicle theft, and drug crimes (drug possession and trafficking in particular). With OIBRS, law enforcement has the option to include geographic information (e.g., street addresses and XY coordinates) in order to allow for mapping crime incidents. For many reasons, not all 2009 crime data were amenable to being mapped. The percentage of incidents able to be mapped is noted throughout the report. One of the maps shown in this report provides an overview of high-frequency crime locations in Youngstown in 2009. It denotes specific locations in which multiple crimes were reported. The map shows that some types of crimes tended to be concentrated in certain locations within the city; for example, although motor-vehicle thefts were reported throughout the city, high-frequency motor-vehicle thefts were especially pronounced in the south-central area of the city. High frequency locations for robberies and thefts were evident along Mahoning Avenue on the west side and Market Street on the south side. Addresses were reported for 14 of 20 murders. They were scattered across several police beats. There were 329 robberies reported to OIBRS in 2009. Of these, 211 were mappable. Robberies were more frequent in the south and west sides of Youngstown. Two police beats reported the most robberies. A total of 1,815 assaults were reported in 2009. Of these, 1,314 were mappable. Analysis identified four hotspots in which multiple assaults were reported. These hotspots were scattered across the city. Map data are also presented for motor-vehicle thefts, burglaries, and drug arrests. Maps and tabular data
