What is the Global Policing Database?

The Global Policing Database (GPD) is a web-based and searchable database designed to capture all published and unpublished experimental and quasi-experimental evaluations of policing interventions conducted since 1950. There are no restrictions on the type of policing technique, type of outcome measure or language of the research.

What types of interventions are in the GPD?

The lack of restrictions on type of policing intervention distinguishes the GPD from other policing research repositories. The GPD captures a wide variety of evaluation research where police are the primary implementers, an intervention partner, or recipients of an intervention.

The GPD includes interventions to:

What types of outcomes are in the GPD?

There are no limits on the type of outcome measures used to evaluate the interventions. The GPD expands beyond crime and disorder outcomes to include other measures such as:

Who can use the GPD?

The GPD will provide a comprehensive database of robust evaluation research for use by police, other social welfare practitioners, policy makers and researchers to inform evidence-based policy and practice.

How can I use the GPD for College of Policing evidence maps?

There are several ways that researchers can extract data for College of Policing evidence mapping projects.

How is the database compiled?

Using innovative systematic review technologies developed at The University of Queensland, the GPD research team are compiling the GPD by systematically searching, retrieving and screening published and unpublished literature that reports on impact evaluations of policing interventions from 1 January 1950.

When was the GPD launched?

Version 1.0 of the GPD was launched in June 2015.

How far back does the GPD go?

The GPD currently contains eligible records dating back to 2014.

The GPD will be updated regularly as more studies are screened and coded.

Who compiled the database?

The Global Policing Database was developed by researchers at The University of Queensland, Australia. The project was funded by the Mayor's Office for Policing and Crime (via The College of Policing) and an Australian Research Council Laureate Fellowship awarded to Professor Lorraine Mazerolle at the University of Queensland.
