| Summary: | We describe the temporal and spatial patterns of crime at unique addresses over a 15-year period, 1998-2012, in a medium-sized Midwestern city. Group-based trajectory analysis of police incidents recorded by the Cincinnati Police Department are combined with geographic analysis for the entirecity, while also highlighting individual address points in one high-crime neighborhood. We find that six trajectories adequately describe the city-wide data, with the low-stable crime trajectory comprising the majority of the places, while the high-stable crime trajectory is just 2.5% of addresses yet consistently has one-third of crime, which accounts for a disproportionate amount of crime. Similar to previous research at the street-block level, small differences in city-wide trends from 1998-2012 obscure large differences within trajectories. Places with very different trajectories of crime are very often located on the same street segment. Nearly allhigh-crime addresses exist among a cloud of low-crime places. This suggests that characteristics of individual addresses are of importance both to crime theory and crime prevention practice. |
