Data were collected and compiled from the files of the Wichita Police Department from January 1, 1977, to December 31, 1977. There were 159 cases of actual and attempted rape reported to the police. Most of the victims were 25 years and under, and 79 women were raped in their own homes. A content analysis was conducted on these 79 cases in order to understand the population that are at-risk for domestic intrusion and its implications for crime control programs. Two victim profiles emerged: (1) a woman who lives alone and (2) a woman who has a special relationship with the offender, who is her ex-boyfriend, a relative, or a friend. For the first victim profile, a crime prevention program can be developed to increase security and reduce the offender's opportunity. However, in the second profile, having a secure home is not the problem, but rather attention must be focused on those who live in the home. Thus, by identifying at-risk populations, police can develop target populations for crime prevention programs and develop effective tools to evaluate their operations. The at-risk crime population technique can permit increased efficiency in the use of an agency's resources through improved evaluation of services and programs. About 20 references are included.
