As the use of administrative data in social research continues to grow, linking survey data to external data sources offers major opportunities to improve data quality, reduce respondent burden, and expand analytical potential. However, obtaining informed consent for data linkage remains a key methodological challenge—particularly in online and self-completion surveys, where consent rates are often substantially lower than in interviewer-administered modes.
This online workshop will explore current evidence and practice around collecting consent to data linkage. We will begin with an overview of the latest research and methodological insights, drawing on the Survey Futures evidence review on consent to data linkage. This will be followed by showcasing ongoing work and practical experiences from research on mode differences in consent to data linkage in Understanding Society.
The session will conclude with an open discussion, providing an opportunity for participants to reflect on challenges, share experiences, and identify priorities for future research and practice.
