Data quality

Quality statement summary:Help on this term

Description
All states and territories provide a range of public housing programs and maintain administrative data sets about these programs. These data sets are provided annually to the AIHW. The data in this collection contains information about public rental housing (PH) dwellings, households assisted and households on the waiting list for the following two reference periods: 2014-15 financial year and point in time at 30 June 2015.

Summary

  • The data collected are an administrative by-product of the management of PH programs run by the jurisdictions 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data sets from which this collection is drawn have inaccuracies to varying degrees, including missing data, out-of-date data and data coding or recording errors.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 jurisdictions. Differences in the data collected and which records are included or excluded from a calculation can affect the coherence of the outputs. Coherence over time has also been affected by changes in methodology.
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 Institute 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 Institute 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 jurisdictions. The finalised data sets are signed off by the jurisdictions and used by the AIHW for reporting and analysis.

Timeliness:Help on this term

The reference period for the Public Housing (PH) collection is based on the financial year (ending 30 June). The specific reference period for these data is 2014–15.

Accessibility:Help on this term

Annual data are reported in Housing Assistance in Australia 2016, which is available publicly on the AIHW website and the Report on Government Services 2016.
 
Users can request additional disaggregation of data which are not available online or in reports (subject to jurisdiction approval) via the AIHW’s online data request system at https://datarequest.aihw.gov.au/_layouts/AdHocDataRequest/LodgeRequest.aspx/. Requests that take longer than half an hour to compile are charged for on a cost-recovery basis.

Relevance:Help on this term

The data collected are an administrative by-product of the management of public rental housing programs run by the jurisdictions and conform well in terms of scope, coverage and reference period.

Classifications used for income, greatest need and vacancy reason are not consistent across the jurisdictions and are mapped to a common 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 jurisdictions capture all data items so substitution is required to calculate some outputs of this collection. Data items affected are gross income and assessable income. In addition, disability status is derived using the receipt of a disability pension as a proxy in some jurisdictions.
  • For some jurisdictions, information about disability is not mandatory to report under program eligibility requirements.
  • Indigenous status is self-identified and not mandatory to report under program eligibility requirements.
  • Most jurisdictions do not update income information for non-rebated householdsoutputs produced that require income information therefore may not be complete and accurate.
  • Estimates produced using the Accessibility/Remoteness Index of Australia (ARIA) are rounded and this may cause discrepancies between estimates produced for regions and those produced for the total of the regions.
  • Waitlist data are reported separately for each social housing program. Where jurisdictions have an integrated waitlist (ACT, NSW, NT, QLD, WA), applicants may be counted for each program for which they are applying. In some jurisdictions, CHOs may additionally maintain and allocate housing to households on their own waiting list.

Specific State/Territory issues:

New South Wales

  • Data on ‘number of Indigenous households at 30 June’ are incomplete and unreliable. These are substituted with estimates based on data from the 2011 census.

Western Australia

  • The Housing Authority WA changed core systems during 2014-15 resulting in a number of differences in recording practices; this means any comparisons with previous years for WA data should be undertaken with caution.

South Australia

  • Housing SA has not supplied the Dwelling History file for the current reporting period.

Tasmania

  • For the 2014-15 reporting period, 1,196 public housing dwellings were transferred to the community sector. This resulted in a 14 per cent decrease in the number of public housing households.
Coherence:Help on this term

Data for individual jurisdictions may not be comparable to previous years due to differences in the accuracy of the data over time. Differences between jurisdictions concerning incomplete or missing information, out-of-date information and coding errors can affect the coherence of the outputs.

Coherence over time has 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 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 2014-15 data with previous years.
  • Measurements of overcrowding cannot be directly compared with figures produced prior to 2009-10 due to a change in methodology.
  • Measurements of underutilisation cannot be directly compared with figures produced prior to 2011-12 due to a change in methodology.

State and Territory Government housing authorities' bedroom entitlement policies may differ from the Canadian National Occupancy Standard (CNOS) which is used in dwelling utilisation calculations.

Specific State/Territory issues:
 

South Australia

  • Housing SA did not supply the Dwelling History file for the current reporting period.

Tasmania

  • For the 2014-15 reporting period, 1,196 Public Housing dwellings were transferred to the community sector. This resulted in a 14 per cent decrease in the number of public housing households.

Northern Territory

  • A total of 5,025 remote dwellings are not currently reported in either the ICH data collection or the public housing data collection, as at 30 June 2015. The NT government has advised that they are aiming to report on these dwellings as part of the Public Housing collection from 2015-16.
