We are conducting a population-based case-control study in the City of Philadelphia to investigate how the nature and whereabouts of adolescents’ daily activities relate to the likelihood of being shot in an assault. Each subject is interviewed using portable, computerized mapping technology, to create a dynamic graphic that provides a minute-by-minute record of how, when, where, and with whom the subject spent time over the course of the past 24 hours as he or she walked or otherwise traveled from location to location and activity to activity. Afterward, characteristics of streets, buildings, and neighborhood populations are linked into each subjects’ space-time activity path. The ultimate goal is to inform communities of place-based risk factors and to identify opportunities to make communities safer. Implications of the methodologic approaches to this innovative space-time analysis will be presented.
