MADIP data and legislation

Multi-Agency Data Integration Project (MADIP) data is used to support government decision making and academic research. It provides evidence to undertake research and evaluation activities, improve the efficiency and targeting of government services, and make policy decisions. Authorised researchers also use this information to undertake research and provide policy advice.

MADIP information is protected by the Census and Statistics Act 1905, which ensures that no information is released in a way that is likely to enable an individual to be identified. There are two broad types of information shared for MADIP: 

  • Linkage information, which usually includes personal identifiers such as name and address, is only used to link the datasets together; it is not used for analytical purposes. For more information about the use of name and address information, please see Keeping integrated data safe.
  • Analytical information may be also used to link datasets, but is primarily used for analysis by authorised researchers. Such information includes age, sex, country of birth, languages spoken, housing tenure, educational qualifications, employment information, income and financial information, and use of healthcare and government support services.

For more detail on what data is available for analysis by authorised researchers, see the MADIP Modular Product.

Legislative Authority

The Australian Bureau of Statistics (ABS) is authorised to collect, compile, analyse, and publish statistics under the Australian Bureau of Statistics Act 1975 and the Census and Statistics Act 1905. In particular, the ABS is authorised by these laws to undertake surveys and the Census, to collect information from other government entities, to link Census data and other information, to produce statistics for analysis, and to publish statistical outputs. The ABS also complies with the Privacy Act 1988 and handles personal information in accordance with the Australian Privacy Principles. Data collected by the ABS (including information used in MADIP) is protected by the secrecy provisions of the Census and Statistics Act 1905. 

Each agency involved in MADIP is authorised by law to collect personal information as part of its core functions, to share that information with the ABS for MADIP, and to use it for policy analysis, research, and statistical purposes. 

This table summarises the various legislative authorities for agencies to share information with the ABS forming an enduring linkage to MADIP for datasets related to income and taxation, education and training, health, migration, government payments, disability and deaths. Further detailed information is available in the report on the 2019 MADIP Privacy Impact Assessment Update, More information about enduring linkages to MADIP can be found on the Data Integration Project Register

Data in MADIP

MADIP evolves to include new and updated sources of data to meet policy and research priorities. Only data that are reasonably necessary for an approved purpose are shared and used. MADIP can also be integrated with selected Business Longitudinal Analysis Data Environment (BLADE) datasets for approved projects. 

The Data Integration Project Register includes a description of the datasets that have an enduring link to MADIP, which allows them to be regularly updated for ongoing research. 

Other datasets have been integrated with MADIP for “once-off” purposes. Once-off data linkages are integrated with MADIP for a specific project or projects and accessed by approved researchers. Once-off data is retained for as long as required for approved projects and typically removed after project completion. In some circumstances, the MADIP Board may review and approve once-off linkages to become an enduring linkage. Data custodians may also approve access to once-off linkages for further projects.
