It describes the nature and extent of campus crime, presents a preliminary model of the correlates of crime on these campuses, and presents a framework for further research based in ecological theory and theories of the community. The data set consists of crimes known to campus police or campus security at 481 institutions, which all had at least 3,000 students and on-campus housing, during the 1989-90 academic year. Data were also provided on crime prevention measures at all 546 campuses. Findings revealed that most crime did not involve violence. Most campus crime involved theft offenses. Findings paralleled earlier findings indicating that certain characteristics of the campuses, the students, and the locations were significantly related to campus crime.
