|Quality statement summary:|
The Australian Institute of Health and Welfare (AIHW) is an independent corporate Commonwealth entity under the Australian Institute of Health and Welfare Act 1987 (AIHW Act), governed by a management Board, and accountable to the Australian Parliament through the Health portfolio.
The AIHW is a nationally recognised management agency. Its purpose is to create authoritative and accessible information and statistics that inform decisions and improve the health and welfare of all Australians.
The AIHW enables other organisations to improve their policies and services and achieve their goals by making better use of evidence—a fundamental requirement for good decision making. It collects and reports on a wide range of topics and issues, including health and welfare expenditure, hospitals, disease and injury, mental health, ageing, homelessness, disability and child protection.
The AIHW also plays a role in developing and maintaining national metadata standards. This work contributes to improving the quality and consistency of national health and welfare statistics. The AIHW works closely with governments and non-government organisations to achieve greater adherence to these standards in administrative data collections to promote national consistency and comparability of data and reporting.
One of the main functions of the AIHW is to work with the states and territories to improve the quality of administrative data and, where possible, to compile national data sets based on data from each jurisdiction, to analyse these data sets and disseminate information and statistics.
Compliance with confidentiality requirements in the AIHW Act, Privacy Principles in the Privacy Act 1988 (Cth), and its data governance arrangements ensures that the AIHW is well positioned to release information for public benefit while protecting the identity of individuals and organisations. It also ensures that data providers can be confident that the AIHW will adhere to data supply terms and conditions.
For further information see the AIHW website www.aihw.gov.au.
The AIHW receives, compiles, edits and verifies the data in collaboration with states and territories. The finalised data sets are signed off by the states and territories and used by the AIHW for reporting, analysis and approved ad hoc data requests. Requests for jurisdiction-level data releases must be signed off by the relevant state or territory.
The reference period for the PH collection is based on the financial year (ending 30 June). The specific reference period for these data is 2018–19.
Users can request additional disaggregation of data which are not available online or in reports (subject to the AIHW's confidentiality policy and state and territory approval) via the AIHW’s online data request system at https://www.aihw.gov.au/our-services/data-on-request. Depending on the nature of the request, requests for access to unpublished data may also incur costs or require approval from the AIHW Ethics Committee.
General enquiries about the AIHW publications can be directed to firstname.lastname@example.org.
Metadata and definitions relating to this data source can be found in the Public Housing and State Owned and Managed Indigenous Housing (PH & SOMIH) data set specification 2018-.
Supplementary information can be found in the housing collection data manuals which are available upon request.
The data collected are an administrative by-product of the management of public housing programs run by the states and territories and conform well in terms of scope, coverage and reference period.
Classifications used for income, disability status, greatest need and vacancy reason are not consistent across the states and territories, however, the states and territories map these data to an AIHW standard.
There are known accuracy issues with the data collected:
State- and territory-specific issues:
New South Wales
Australian Capital Territory
States and territories may publish their own analysis of public housing data which may vary in scope from this collection.
Data for individual states and territories may not be comparable to previous years due to changes in systems and processes which have led to differences in the accuracy and completeness of the data over time. Differences between states and territories concerning social housing management systems, incomplete or missing information, out-of-date information and coding errors can affect the coherence of the outputs.
Coherence over time has also been affected by changes in methodology:
State and Territory Government housing authorities’ bedroom entitlement policies may differ from the CNOS which is used in dwelling utilisation calculations.
In 2017–18, letters of first and surname and a date of birth accuracy indicator were added to the collection in order to produce a statistical linkage key (SLK). Not all components were provided by all jurisdictions. See the state- and territory-specific information in the ‘accuracy’ section for details.
The locality of the dwelling was included in the collection for the first time in 2017–18.
