Data from a variety of sources about crime in schools and colleges and characteristics of the people who commit these offenses provide key input in developing theories and operational applications that can help combat crime in this nation's schools, colleges, and universities. Given the myriad of data available, the objective of this study is to particularly analyze data submitted to the FBI's (Federal Bureau of Investigation) UCR (Uniform Crime Reporting) Program by law enforcement agencies. It examines specific characteristics of offenders and arrestees who participated in criminal incidents at schools and colleges from 2000 through 2004. In summary, this study, over the 5-year period, found that 3.3 percent of all incidents reported via NIBRS (National Incident-Based Reporting System) involved school locations. The number of crime in school-related incidents was highest in October. Offense records were also most likely to include the use of personal weapons (hands, fists, feet, etc.), while reports of the offender's use of alcohol, computers, and/or drugs were minimal. Reported offenders of crime in schools were most likely 13-15 year old white males who the victims reportedly knew; however, there was nearly an equally large number of 16-18 year old reported offenders. More than half of the arrestees associated with crime at school locations were arrested for simple assault or drug/narcotic violations. Arrestees had similar characteristics to the reported offenders, most likely being reported as 13-15 year old white non-Hispanic males who were residents of the community of the school location where the incident was reported.
