Data quality

Quality statement summary:Help on this term

All states and territories provide the AIHW with Home Purchase Assistance (HPA) data from their administrative systems. The AIHW compiles this data for annual national reporting on the National Affordable Housing Agreement and internal publications and bulletins.

Care should be taken when comparing data across jurisdictions, given differences in the types of HPA programs run and differences in the broader jurisdictional housing systems.

Care should also be taken when comparing data across time due to changes in the underlying HPA programs and how they are classified.

All states and territories provide HPA and maintain administrative data sets about these programs. These data sets are provided annually to the AIHW. This collection contains data about HPA received during 2011–12 financial year and repayable forms of HPA provided prior to the 2011-12 financial year for which monies remain outstanding at the commencement of the 2011-12 financial year.

Institutional environment:Help on this term

The 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 statutory authority established in 1987, governed by a management Board, and accountable to the Australian Parliament through the Health and Ageing 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, (Cth) 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 HPA data in collaboration with jurisdictions, which retain ownership of the data and must approve any jurisdiction level output before it is released. The finalised data sets are used by the AIHW for collation, reporting and analysis.

Timeliness:Help on this term

The reference period for the HPA data collection is based on the financial year (ending 30 June). Data are collected and published annually. The specific reference period for these data is 2011–12.

Summary data items from the 2011-12 HPA data collection were first published in the National Agreement Performance Information 2011-12: National Affordable Housing Agreement (Steering Committee for the Review of Government Service Provision) in December 2012.

Accessibility:Help on this term

Annual data are reported in National Agreement Performance Information 2011-12: National Affordable Housing Agreement http://www.pc.gov.au/__data/assets/pdf_file/0008/123893/affordable-housing-2011-12.pdf and in AIHW publications including Housing Assistance in Australia and Australia’s Welfare.

Relevance:Help on this term

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

HPA for the purpose of this collection relates to the provision of financial assistance to enable households to improve their access to home ownership and includes:

  • direct lending (including government loans, shared equity loans and bridging loans)
  • deposit assistance
  • interest rate assistance
  • mortgage relief
  • other assistance grants.

It excludes:

  • non-financial assistance, e.g. home purchase advisory and counselling services
  • home renovation/maintenance services
  • sale to tenant programs.

In-scope households are those that received HPA assistance in the 2011-12 financial year and those that received repayable forms of HPA provided prior to the 2011-12 financial year for which monies remain outstanding at the commencement of the 2011-12 financial year.

Not all jurisdictions collect or update all data items for every household so data item substitutions are made in some cases. Data collected are appropriate for reporting outputs from the HPA programs of state and territory governments.

Accuracy:Help on this term

There are some 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 and data coding or recording errors.

Care should be taken in interpreting the number of households assisted by each type of assistance with respect to inferring a total number of households assisted by each jurisdiction. Some households received multiple types of assistance. Thus, a simple sum of the number of households assisted across each assistance type would overstate the total number of households assisted due to double counting. Where households receive multiple types of home purchase assistance, the total number of households assisted by a jurisdiction will be less than the sum of the number of households assisted by each type of assistance.
Coherence:Help on this term

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.

Specific State/Territory issues are:

Victoria

A change in Victoria’s accordance with the scope of the collection in 2011-12 has led to a change in the reported number of households assisted under ‘Other’ assistance. The change in accordance with the scope is constituted by the exclusion of a home renovations scheme that, prior to the 2011-12 collection, had been included under ‘Other’ assistance. 

Queensland

A change in Queensland’s accordance with the scope of the collection in 2011-12 has led to a change in the reported number of households assisted under direct lending. The change in accordance with the scope is constituted by the exclusion of aspects of sale to tenant programs that were not direct lending that prior to the 2011-12 collection, were reported under direct lending.  Thus, data is not comparable with data from 2010-11 and earlier reference periods.

Western Australia

A change in Western Australia’s accordance with the scope of the collection in 2011-12 has led to changes in the reported number of households assisted by direct lending, interest rate assistance and ‘Other’ assistance.  Thus, data is not comparable with data from 2010-11 and earlier reference periods. The changes in Western Australia’s accordance with the scope are detailed below.

  • Prior to the 2011-12 collection, ‘Other’ assistance was exclusively constituted by loans that funded the state’s share of equity in shared equity dwellings, and thus, was not financial assistance to households. These loans funding the state’s share of equity in shared equity dwellings have been excluded from the 2011-12 collection. In the 2011-12 collection, ‘Other’ assistance is constituted by waived mortgage insurance on direct lending.
  • In the 2011-12 collection, the number of households reported as assisted by direct lending included those households that were issued loans in the 2011-12 financial year and those households that held loans that were issued in a previous reference period.  In the 2010-11 collection, this number included only those households that were issued loans in the 2010-11 financial year.
  • Loans issued after October 2009 received a variable rate 0.78%above loans issued prior to October 2009. In the 2010-11 collection the jurisdiction included households with loans on the lower variable interest rate, those issued prior to October 2009, as in receipt of interest rate assistance. In the 2011-12 collection these households were included under direct lending, since they held loans issued in a previous financial period; the relative interest rate discount was, however, footnoted (Table NAHA.e.1 in the National Agreement Performance Information 2011-12: National Affordable Housing Agreement), rather than included in the table under interest rate assistance.
Australian Capital Territory

A change in accordance with the scope of the collection in 2011-12 has led to a change in the reported number of households assisted under direct lending. Prior to the 2011-12 collection, the ACT did not report households that held loans on home purchase assistance provided prior to the collection year. This information provided under direct lending for 2011-12 pertains to a program that closed to new entrants in 1996. Thus, data is not comparable with data from 2010-11 and earlier reference periods.
