Quality statement summary:Help on this term

Description

Four states and territories—New South Wales, Queensland, South Australia and Tasmania—provide a range of State Owned and Managed Indigenous Housing (SOMIH) programs and maintain administrative data sets about these programs. Extracts of these data sets are provided annually to the Australian Institute of Health and Welfare (AIHW).

This collection contains information about SOMIH dwellings, households assisted and households on the waiting list. Data are provided for the following two reference periods: 2015–16 financial year and point in time at 30 June 2016.

Summary

  • The data collected are an administrative by-product of the management of SOMIH programs and conform well in terms of scope, coverage and reference period.
  • The administrative data sets from which this collection is drawn have inaccuracies to varying degrees, including missing data, out-of-date data and data coding or recording errors.
  • Care is required when comparing outputs across states and territories. Differences in the data collected, including which records are included or excluded from a calculation can affect the coherence of the outputs. Coherence over time has been affected by changes in methodology (see ‘coherence’ section for details).
Institutional environment:Help on this term

The Australian Institute of Health and Welfare (AIHW) is a major national agency set up by the Australian Government under the Australian Institute of Health and Welfare Act 1987 to provide reliable, regular and relevant information and statistics on Australia's health and welfare. It is an independent corporate Commonwealth entity established in 1987, governed by a management Board, and accountable to the Australian Parliament through the Health portfolio.

The AIHW aims to improve the health and wellbeing of Australians through better health and welfare information and statistics. It collects and reports information on a wide range of topics and issues, ranging from health and welfare expenditure, hospitals, disease and injury, and mental health, to 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.

The Australian Institute of Health and Welfare Act 1987, in conjunction with compliance to the Privacy Act 1988, (Commonwealth of Australia), ensures that the data collections managed by the AIHW are kept securely and under the strictest conditions with respect to privacy and confidentiality.

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 and analysis.

Timeliness:Help on this term

The reference period for the SOMIH collection is based on the financial year (ending 30 June). The specific reference period for these data is 2015–16.

Accessibility:Help on this term

Data are reported in the AIHW's annual Housing assistance in Australia reports and the Productivity Commission's annual Report on government services.

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://datarequest.aihw.gov.au. 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 AIHW publications can be made to the Digital & Media Communications Unit on (02) 6244 1026 or via email to info@aihw.gov.au.

Interpretability:Help on this term

Metadata and definitions relating to this data source can be found in the National housing and homelessness data dictionary (AIHW Cat no. HOU269).

Supplementary information can be found in the housing collection data manuals which are available upon request.

Relevance:Help on this term

The data collected are an administrative by-product of the management of SOMIH programs and conform well in terms of scope, coverage and reference period. SOMIH programs are delivered in only 4 states and territories—New South Wales, Queensland, South Australia and Tasmania.

Classifications used for income, 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.

Accuracy:Help on this term

There are known accuracy issues with the data collected:

  • The administrative data sets from which this collection is drawn have inaccuracies to varying degrees including missing data, out-of-date data and data coding or recording errors.
  • Not all states and territories capture all data items. For those outputs that are calculated using gross income, New South Wales and South Australia use assessable income instead. In addition, disability status is derived using the receipt of a disability pension as a proxy in some states and territories.
  • Information about disability is not reported under eligibility requirements for some programs.
  • Indigenous status is self-identified and not reported under eligibility requirements for some programs.
  • Most states and territories do not update income information for non-rebated households. Outputs produced that require income information do not include households with missing income and therefore may not be complete.
  • Estimates for Accessibility/Remoteness Index of Australia (ARIA) regions and those produced for the total of the regions may differ due to rounding.
  • Waitlist data are reported separately for each social housing program. Where jurisdictions have an integrated waitlist (New South Wales and Queensland), applicants may be counted once irrespective of the number of programs for which they are applying.

 

State- and territory-specific issues:

New South Wales

  • Since a system change in 2010, New South Wales continues to report problems encountered when linking files containing date variables within their system. This may occur when linking ‘Dwelling history’, ‘Household’ and ‘Waitlist’ files. Where date variables contradict between files, they are recoded as missing.

Queensland

  • Individual Indigenous status of SOMIH tenants is not collected. SOMIH households are assumed to be Indigenous households.

South Australia

  • For the current reporting period, Housing SA did not supply the ‘Dwelling history’ file which includes the variables necessary for the calculation of turnaround time

Tasmania

  • The introduction of the new Housing Assessment Prioritisation System (HAPS) in June 2015 has meant that ‘reasons for greatest need’ are unavailable.
Coherence:Help on this term

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 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:

  • Measurements using low income cannot be directly compared with low income figures produced prior to 2009–10 due to a change in methodology. Low income cut-offs were again revised for 2014–15 data based on ABS 2013–14 Survey of Income and Housing results. This led to substantial increases in the number of households considered to be receiving a low income. Care is therefore also required when comparing data from 2014–15 onwards with previous years.
  • Measurements of overcrowding cannot be directly compared with figures produced prior to 2009–10 due to a change in methodology. Prior to 2009–10, overcrowding was measured using a proxy standard of ‘2 or more bedrooms are required’. From 2009–10 onwards, overcrowding was measured using the Canadian National Occupancy Standard (CNOS) of ‘1 or more bedrooms are required‘.
  • Measurements of underutilisation cannot be directly compared with figures produced prior to 2011–12 due to changes in methodology. Prior to 2009–10, underutilisation was measured using a proxy standard of ‘2 or more spare bedrooms’. From 2009–10 to 2010–11, underutilisation was measured using the CNOS of ‘1 or more spare bedrooms‘. From 2011–12 onwards, underutilisation was measured using the revised CNOS of ‘2 or more spare bedrooms‘.

State and Territory Government housing authorities’ bedroom entitlement policies may differ from the CNOS which is used in dwelling utilisation calculations.

 

State- and territory-specific issues:
South Australia

  • Since 2012–13, Housing SA has been unable to provide the ‘Dwelling history’ file which includes the variables necessary for the calculation of turnaround time.

Tasmania

  • Reasons for ‘greatest need’ data are unavailable due to the introduction of new systems.
