Data Integration: Combining data for a broader perspective

The Australian Bureau of Statistics (ABS) and Australian Institute of Health and Welfare (AIHW) are Accredited Integrating Authorities that were 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 supported a coordinated national approach to the development of integrated data assets to build enduring longitudinal data about populations and businesses.

The ABS continued 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 included 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 Agriculture, Water and the Environment, CSIRO, Geoscience Australia and the Department of Industry, Science, Energy and Resources, also developed the Location Index to provide a standard, repeatable system to integrate data across the economy, society and environment based on location.

The ABS and AIHW built 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 enables data assets held at the ABS to be combined with data either held centrally at the AIHW or in state agencies where AIHW has created linkage keys.

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

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