Data for this study came from a special one-time supplement conducted in conjunction with the National Crime Victimization Survey. Findings of the study support the routine activity theory by showing that factors related to exposure to risk, proximity to potential offenders and target attractiveness are stronger predictors of the perception of risk at the workplace than demographic and socioeconomic variables. Results also indicate that the perception of the workplace as unsafe is very similar for males and females and fairly similar for people in different age categories. There are differences in the factors that trigger the perception of risk in the workplace among Caucasians, African Americans and Hispanics. This research suggests the need for studies on different social domains such as homes and schools. In addition, it is important that future studies include persons from different racial and ethnic backgrounds because variables not included in this study, such as language barriers, immigration and cultural barriers, may all influence the way people react to crime.
