The term 'elderly victim syndrome' is proposed for the group of victimizations and predispositions to victimization to which the elderly seem vulnerable. Much of the lack of awareness regarding victimization of the elderly is due to a paucity of data, but a number of recent victim studies have begun to shed light on this problem. For the most part, these studies show that the elderly are generally undervictimized, especially with regard to crimes of violence. However, they are overvictimized with respect to burglary and purse snatching. In spite of this, the fear of the elderly is directed especially toward crimes of personal violence -- murder, aggravated assault, and rape. To explain the patterns of victimization of the elderly, a concept of differential vulnerability has been espoused. Passive vulnerability refers to a condition whereby a victim's status is recognized as exploitable; active vulnerability refers to a condition whereby a victim's behavior contributes interactionally to a crime. Victimization of the elderly is not as great as one would suppose because vulnerability of the aged is, for the most part, unobtrusive in nature. Much more research needs to be conducted in this area of differential vulnerability of the elderly if rational strategies are to be developed to protect elderly citizens from victimization.
