While the vast majority of research on the causes and consequences of fear of crime has been focused on personal fears, Warr and Ellison have suggested that fears for one’s family are both more common and more important in explaining protective actions like gun ownership. The present work not only provides new evidence supporting these findings but also expands our understanding of altruistic fears in two important directions: by exploring the potential sources of such fears in exposure to crime and by exploring new potential responses to such fears, including residential mobility decisions. The results suggest that altruistic fears are rooted in personal experiences with victimization and personal evaluations of the local danger posed by crime—though the ways that people react to victimizations depend on their opportunities for personal versus altruistic fears. In turn, altruistic fears are associated with taking protective measures, withdrawing from local organizational participation, and the desire and intent to flee neighborhoods altogether. However, the article also acknowledges important independent roles for personal fears and cognitive evaluations of danger, ultimately recommending a more holistic perspective on reactions to crime.
