This chapter discusses the Association of Police and Crime Commissioners’ (APCC) role in enabling and supporting Police and Crime Commissioners (PCCs) and their offices to use data to monitor performance, strengthen accountability, support partnerships, and commission evidence-based services, as well as in ensuring that data is being used ethically. It highlights the role of data sharing agreements in partnership working and the limited availability of specialist data analysts and issues with data literacy in PCCs’ offices, focusing on the APCC’s role in addressing both these issues. It considers how PCCs appropriately balance engagement with data analysis with their role as elected politicians and ‘the public’s voice in policing’, concluding that while data has a critical role in framing public engagement and enabling more effective and efficient delivery against the public’s priorities, it is no substitute for the community engagement and the responsiveness to local context and priorities that is at the heart of the PCC’s role. A blend of evidence-based approaches and real-world input allows PCCs to implement balanced, responsive, and inclusive community safety and crime reduction measures, ensuring that evidence-informed policing remains accountable to the public and responsive and relevant to local needs, priorities, and resources.
