Public sector use of data and algorithms

Building evidence on how data-driven technologies are shaping public services, and supporting approaches to public-sector algorithm accountability

The context

Governments around the world are increasingly turning to data-driven technologies and algorithms to automate or support decision-making and deliver public services. These tools are being used in the delivery of social-care and welfare provision, the detection of fraud, policing and surveillance, and urban planning. 

Increased data collection and linkage is also being used to shape more targeted, predictive public services and streamline decision-making, as governments seek to improve service provision, increase efficiency or lower costs. Such approaches were accelerated during the coronavirus pandemic, and are being posited as a key mechanism for recovery and growth in the aftermath of COVID-19. 

While new data-driven tools have the potential to transform how public services are run and how citizens interact with them, they also pose several political, economic, legal and ethical questions. And growing evidence suggests that algorithmic systems in public-service delivery frequently lack accountability and transparency in their implementation, as well as around decisions about whether and why to use them.

While a handful of examples, such as the 2020 Ofqual A-Level algorithm, which triggered protests and a rallying cry to ’fuck the algorithm’, little is authoritatively known about how data and algorithmic decision-making systems are evolving in public services and government. New measures to track, examine and assess the impact of data-driven tools in public service provision are starting to emerge, as exemplified by AlgorithmWatch’s authoritiative study of automated decison-making tools across Europe. We are also seeing attempts to improve accountability in the use and provision of algorithms in the public sector, as evidenced in our joint global study with AI Now and the Open Government Partnership. However, we remain in the nascent ‘first wave’ stage of transparency and accountability measures. 

Ada’s approach

Our research aims to increase the visibility of public sector use of data and algorithms with a view to encouraging informed scrutiny of such systems. We also aim to co-create and pilot potential novel approaches to improve transparency, assess impact, increase public participation, and improve accountability. Through primary research with public-sector partners, secondary analysis and synthesis of emerging trends, and engagement with the public, this programme aims to support greater understanding of the uses and impacts of data-driven tools in the public sector, and develop recommendations for policymakers and public-sector practitioners on how to use and govern data and data-driven technologies. Examples of our work include: 

Building evidence and case studies

  • We are undertaking ethnographically-informed case study research of the use of predictive analytics by one London local authority, with a view to isolating key lessons, best practices and concerns about the deployment of algorithmic decision-making tools in public service provision. 

Defining key terms, synthesis and conducting high-level surveys of the field

  • We examined key terms such as ‘transparency’ and ‘explainability’, and have produced an explainer on a range of transparency mechanisms available in the public sector domain. 
  •  In collaboration with AI Now and the Open Government Partnership, we co-published a survey of the first wave of algorithmic accountability policy mechanisms in the public sector.  

Public engagement and deliberation to understand public expectations about the use of data and algorithms in the public sector

  • We have collaborated with the Geospatial Commission to deliver a public dialogue on the use of location data for public-service delivery. 
  • In 2022 we will explore possible public engagement around justice system data. 

The impact we seek

Our Public sector use of data and AI programme enables us to achieve our strategic goals in the following ways: 

  • We are rebalancing power over data and AI through exploring tools and mechanisms to improve public-sector algorithmic accountability. 
  • We are amplifying the voices of people by creating participatory mechanisms for citizens to contribute to the design of public-sector algorithmic and data-driven approaches.
