The Evidence-Based Policing Matrix is a research-to-practice translation tool that categories and visualizes all experimental and quasi-experimental research on police and crime reduction according to three common dimensions of crime prevention – the nature of the target, the extent to which the strategy is proactive or reactive, and the specificity or generality of the strategy. This categorization and visualization of policing evaluation studies reveals three-dimensional clusters of effective studies, which we refer to as "realms of effectiveness." These realms of effectiveness provide insights into the nature and commonalities of effective police strategies and can be used by police agencies to guide various aspects of their operations.
