Big Data in Social Welfare: The Development of a Critical Perspective on Social Work's Latest “Electronic Turn”

“Big data” initiatives that aim to bring together and mine data from multiple databases across government and non-government agencies promise new insights into the delivery of social services. However, as debates in other disciplines have shown, big data poses challenges as well as opportunities. This article provides an overview of the ethical issues in relation to big data, which extends into an examination of the practice issues for big data applied to the social welfare sector. In particular, the claims for objectivity made for big data are problematised through an exploration of what data are available in social welfare and the processes of big data collection and analysis, which are different from, but related to, data integrity. The aim is to stimulate debate within the sector in order to contribute to the development of a critical, cautious, but open approach to social work's latest “electronic turn”.
