According to this perspective, the probability of criminal victimization varies by time, space, and social setting and by the extent to which routine activities increase target suitability and reduce effective guardianship. The patterns and correlates of conventional crimes are consistent with this approach. Crimes against property tend to be committed disproportionately against those whose lifestyle leave their possessions least effectively guarded. Crimes against persons have some different correlates than do crimes against property, but most of these differences are consistent with the lifestyle/exposure theory. For typical crimes, victims (and offenders) are most likely to be young, male, and engage in evening activities away from home. Thus, their lifestyles place them in social settings with a higher risk of criminal victimization. Strategies for crime control consistent with this theory would include those to increase effective guardianship and reduce the availability of motivated offenders. 1 figure and 7 annotated references.
