The Global Policing Database (GPD) is a web-based and searchable database designed to capture all published and unpublished experimental and quasi-experimental evaluations of policing interventions conducted since 1950.



The GPD is distinct from other policing repositories. It captures evaluations of interventions conducted by police, with police and on police.

The GPD includes all types of policing interventions. It includes interventions that target problem people, situations and places; assist victims; develop organizational capacities (including technologies); improve interviewing techniques; enhance police wellbeing, and more.

The GPD has no limits on intervention outcomes. The GPD goes beyond crime and disorder outcomes, collecting studies that include outcomes such as fear of crime, perceptions of police, organizational effectiveness, physical and mental wellbeing, and more.

The GPD is a comprehensive database of robust evaluation research. It can be used by police, researchers, social welfare practitioners, and policy makers to inform evidence-based policy and practice.


The Global Policing Database was developed by researchers at The University of Queensland (UQ), and Queensland University of Technology (QUT), Australia.

Development of the GPD was funded by the UK College of Policing (including via the Mayor's Office for Policing and Crime) and an Australian Research Council Laureate Fellowship awarded to Professor Lorraine Mazerolle at the University of Queensland.
