Administrative data is always been a potentially important resource for the social and health sciences; the opportunity to analyse population data across a wide range of domains is an exciting one. The slow but gradual build of infrastructure to support access to such data and the advent of data science to link data together and support the complex analysis both within academia and beyond means that the potential is gradually being realised.

The International Conference for Administrative Data Research is a growing annual event aimed at researchers who use administrative data to better understand populations and societies. This year’s conference attracted over 130 submissions; with a mixture of substantive research, methodology and policy. The gradual maturation of this genre of social and health data sciences means that we are, collectively, beginning to understand more fully the complexities of analysing data which have not been collected for research.

This collection of abstracts from the conference reflects both the growing maturity and the diversity of the field. I hope that you enjoy them and they encourage those of you who are not yet engaged with this growing field to do so.
