Place-randomized trials are an important vehicle for generating evidence about “what works” in criminology. Place-based randomized trials are a form of cluster randomization that involves identifying a sample of places (for instance, crime hot spots) and randomly allocating these locations to different police or community interventions. Random allocation assures a fair comparison among the interventions, and when the analysis is correct, a legitimate statistical statement of confidence in the resulting estimates of their effectiveness can be made.
This entry provides basic definitions and practical counsel about the use of such trials in generating evidence in crime prevention. It also identifies issues, ideas, and challenges that might be addressed by future research. Finally, it discusses the special analytic difficulties that may occur in the development of place-randomized trials as opposed to more traditional trials where individuals are the units of allocation and analysis.
