Each Australian Government agency involved in the 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 the MADIP, and to use it for policy analysis, research, and statistical purposes. Only data that is necessary for the project is shared and used in the MADIP.
MADIP information is used to support decision making by governments at all levels. It enables them to undertake their own information and evaluation activities, improve the efficiency and targeting of government services, and make policy decisions based on evidence. 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 types of information shared for the MADIP:
- Personal information such as name, geocoded address, and date of birth 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 the MADIP Frequently Asked Questions
- Demographic information may be used to link datasets, and are 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.
The 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 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 the MADIP) is protected by the secrecy provisions of the Census and Statistics Act 1905.
