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The Global Policing Database (GPD) is a web-based and searchable database designed to capture all published and unpublished experimental and quasi-experimental evaluations of policing interventions conducted since 1950.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

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 a selection of eligible records between 2004 - 2018.
The GPD will be updated regularly as more studies are screened and coded.

How do I cite the database?

If you use the Global Policing Database in your research, please acknowledge the database by using the following citation:

What is the GPD search strategy?

The GPD’s systematic search covers 42 academic databases from 1950 to 2018. The search identified more than 200,000 unique records. Searches of grey literature and non-English sources are currently in progress.

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the GPD research team are compiling the GPD by systematically searching, retrieving and screening published and unpublished literature that reports on impact evaluations of policing interventions from 1 January 1950.

Where do I find the GPD protocol?

The full GPD protocol can be downloaded here.    

How is the GPD screened?  

Each title and abstract from the search is screened for relevance to policing. The full text for all eligible records is then re-screened for research design and quality assurance.  

How confident can I be in the GPD?   

The GPD search strategy was rigorously piloted. All screeners complete standardised training and testing, and all screening is subject to extensive fidelity checks.

Does the database contain full-text documents that I can read?

The full-text version of research in the Global Policing Database are not accessible via the website, unless there is an open-access version of the document. However, the GPD will provide the full citation and abstract for each eligible record.

How can the GPD save me time and money?

Using the GPD as a primary search location can save weeks of searching and information retrieval. Screening time can also be reduced for research between 2002 and 2018, because these abstracts have already been assessed for relevance to policing.  

How can I access the GPD data?

There are two ways to use the GPD:  
Option 1. Search the free online GPD database. This option provides access to all fully screened records currently uploaded to the GPD.
Option 2. Engage with the GPD researchers to access the systematic search data. We can help develop and pilot SQL search queries to extract records into your preferred format, for any time frame between 1950 and 2018.
