Two major conclusions can be drawn from research on behavioral responses to crime. First, types of behavioral response tend to occur independently of one another. Since each type of response is a function of a different set of factors, strategies to encourage one type of response may be ineffective in promoting others; e.g., producing fear of crime may produce avoidance behavior but may diminish collective crime prevention activities. Second, approaches to crime prevention must be tailored to the community. Generally, collective crime prevention approaches are more difficult to establish in lower income, heterogeneous neighborhoods, where residents are more likely to fear and mistrust one another and there is a lower rate of participation in formal organizations. Organized approaches to crime prevention must reflect the social structure of the targeted neighborhoods. 73 references.
