Data Integration: Combining data for a broader perspective

Australian Institute of Health and Welfare (AIHW) are Accredited Integrating Authorities that are funded to build on their existing data integration and linkage capabilities. They ensure integrated data is de-identified, confidentialised and analysed in safe, secure and controlled environments.

DIPA supports a coordinated national approach to the development of integrated data assets to build enduring longitudinal data about populations and businesses.

The ABS is continuing to expand key data assets, including the Multi-agency Data Integration Project (MADIP) and Business Longitudinal Analytical Data Environment (BLADE) with more recent data and new datasets to meet the policy needs of government and the DIPA data analytical units. This expansion includes new data (from a range of sectors and sources, including surveys) as well as longitudinal information to enable insights into trends over time.

The ABS, in collaboration with the Department of the Environment and Energy, CSIRO, GeoScience Australia, the Department of Agriculture and Water Resources and the Department of Industry, Innovation and Science, is also developing the Location Index to provide a standard, repeatable system to integrate data across the economy, society and environment based on location.

A Longitudinal Linked Employer and Employee Dataset (L-LEED) is also being developed under DIPA. The prototype is led by the Treasury and Department of Education and Training, and is being built by the Australian Taxation Office and Data61.

The ABS and AIHW are building interoperability to increase efficiency in creating integrated data products between the two agencies, and to facilitate better use of person-centred data. ABS-AIHW interoperability will enable data assets held at the ABS to be combined with data either held centrally at the AIHW or in state agencies where the AIHW has created linkage keys.

AIHW is developing technical infrastructure and tools to provide consistency across the high quality data integration system which underpins DIPA, and will ensure interoperability with state and territory data integration resources.
