MADIP data and legislation

Each agency involved in the Multi-Agency Data Integration Project (MADIP) is authorised by law to collect personal information as part of its core functions, to share that information with the Australian Bureau of Statistics (ABS) for MADIP, and to use it for policy analysis, research, and statistical purposes.

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.

Data in MADIP

Only data that are reasonably necessary for an approved purpose are shared and used. The
Data Integration Project Register includes a description of the datasets that have an enduring link to MADIP, which allows them to be updated for ongoing research.

MADIP will evolve to include new and updated sources of data to meet policy and research priorities. This includes supporting Australia's response to the COVID-19 pandemic, by the expansion of social security data to include the JobSeeker payment and exploring the addition of 2020 JobKeeper and Single Touch Payroll data to inform research into labour market impacts and outcomes. MADIP can also be integrated with selected Business Longitudinal Analysis Data Environment datasets for approved projects.

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 use of name and address information, please see Keeping integrated data safe.
  • Analytical information may be also used to link datasets, but is primarily also 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.
