Following the release of a study exploring the feasibility of linking three community-sector data collections, the Australian Institute of Health and Welfare was funded to link available child protection, juvenile justice and Supported Accommodation Assistance Program data. Analysis of the linked data shows that children and young people who are involved in one of these three sectors are more likely to be involved in another of the sectors than the general population. While the results are limited by data availability, the project highlights the valuable information that can be gained by data linkage.
