The level of concern about security problems at the University of Maryland at College Park and the use of available security measures and services were investigated in May 1983. A randomly-selected sample of 764 students, 571 employees, and 31 campus police were surveyed. Higher response rates were obtained from women than from men, and from on-campus students than from commuters. Among employees, the estimated response rates were highest for associate staff (64 percent), followed by faculty (30 percent), and classified employees (25 percent). More women than men respondents and more student than employee respondents were concerned for personal safety, and the greatest concern was for night hours. The primary areas of concern were walking in or near parking lots and walking elsewhere outdoors. Substantial proportions of students expressed concern about their safety in the residence halls, the libraries, classroom buildings, and other campus buildings. Awareness and use of the following security services were also determined: campus police vehicle patrols and escort service, the residence hall security program, crime prevention programs, and police assistant patrols at doors to buildings.
