Data Analytics and Algorithmic Bias in Policing

Download PDF(1MB)

This paper summarises the use of analytics and algorithms for policing within England and Wales, and explores different types of bias that can arise during the product lifecycle.

The use of data analytics and algorithms for policing has numerous potential benefits, but also carries significant risks, including those relating to bias. This could include unfair discrimination on the grounds of protected characteristics, real or apparent skewing of the decision-making process, or outcomes and processes which are systematically less fair to individuals within a particular group. These risks could arise at various stages in the project lifecycle.

Algorithmic fairness cannot be understood solely as a matter of data bias, but requires careful consideration of the wider operational, organisational and legal context, as well as the overall decision-making process informed by the analytics.

While various legal frameworks and codes of practice are relevant to the police’s use of analytics, the underlying legal basis for use must be considered in parallel to the development of policy and regulation. Moreover, there remains a lack of organisational guidelines or clear processes for scrutiny, regulation and enforcement. This should be addressed as part of a new draft code of practice, which should specify clear responsibilities for policing bodies regarding scrutiny, regulation and enforcement of these new standards.
