Objectives: To conduct a systematic review examining the extent to which there is crime displacement or a diffusion of crime control benefits in social control interventions implemented in medium sized or large geographic areas.
Methods: A number of search strategies were used to identify and code eligible experimental or quasi-experimental studies that measured displacement in areas larger than crime hot spots. A total of 33 publications covering 43 quasi-experimental studies were identified as eligible. Nineteen of these publications covering 20 studies were included in a meta-analysis.
Results: The narrative results overall suggest that displacement is not a common occurrence in interventions implemented at larger units of geography and a diffusion of crime control benefits is somewhat more likely to occur. The effect sizes from the meta-analyses suggest that, while the interventions, on average, were associated with a significant decline in crime, displacement was not likely to occur. The meta-analyses found no significant overall evidence of displacement or a diffusion of benefits.
Conclusions: These findings are in line with previous reviews that have focused on displacement at smaller geographic units. When examining larger geographic scales and a broader array of interventions, spatial displacement is still a fairly unlikely occurrence.
