|Quality statement summary:|
The Australian Institute of Health and Welfare (AIHW) is a 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, (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.
Data are not collected annually. Surveys for PH and CH were conducted in 2001, 2003, 2005, 2007, 2010 2012, and 2014. Surveys for SOMIH were conducted in 2005, 2007, 2012, and 2014. For SOMIH tenants in 2014, surveys were completed via mail-out for two jurisdictions (South Australia and Tasmania) and face-to-face interview in the other two jurisdictions (New South Wales and Queensland).
The fieldwork for 2014 was conducted from 6 May–22 July for the ACT. For all other jurisdictions, fieldwork was conducted from 14 May–14 August 2014.
Fieldwork for the SOMIH face-to-face component was undertaken in NSW from the 19 May-5 June and in QLD from 3 June-2 July.
Data on the characteristics of the household and its members relate to the time of the survey. Data on tenant satisfaction relate to the 12 months up to the time of the survey.
Published results from the 2014 NSHS are available on the AIHW website, see National Social Housing Survey 2014: national report. Access to the confidentialised unit record file may be requested through the AIHW Ethics Committee.
Users can request additional disaggregations 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.
General enquiries about AIHW publications can be made to the Digital & Media Communications Unit on (02) 6244 1032 or via email to firstname.lastname@example.org.
|Interpretability:||Information to aid in interpretation of 2014 NSHS results are available on the AIHW website including the 2014 NSHS Technical Report, code book and other supporting documentation.|
|Relevance:||The 2014 NSHS includes tenants from PH, CH and SOMIH. The Indigenous Community Housing (ICH) sector was excluded from the survey. All states and territories participated in the survey if the relevant program operated in their jurisdiction. The data were collected via a mail-out self-completed paper questionnaires and face-to-face interviews. All remoteness areas were included in the sample. For the postal component of the survey, the speed of delivery to, and returns from, more remote locations may have affected the number of responses received from tenants in these areas.|
Response rates and contact rates
Overall, 42,827 questionnaires were sent to tenants in PH, CH and SOMIH (South Australia and Tasmania only), of which 12,594 questionnaires were categorised as being complete and useable, representing a response rate for the 2014 survey of 32.4%; considerably higher than the 2012 survey of 16.3%.
For the two SOMIH jurisdictions where the respondents completed the survey completed the survey face-to-face (New South Wales and Queensland), a total of 1,723 interviews were attempted and 1,001 interviews were completed with an overall response rate of 58.1%.
A low response rate does not necessarily mean that the results are biased. As long as the non-respondents are not systematically different in terms of how they would have answered the questions, there is no bias. Given the relatively low response rates for this survey, it is likely there is some bias in the estimates. No adjustments have been made to any potential non response bias.
Scope and coverage
The 2014 NSHS was designed to meet minimum reliability objectives for key variables for each housing program.
To produce reliable estimates, minimum sample sizes were set for each housing collection: PH (500), CH (350) and SOMIH (500). An additional overall 5350 booster sample was included: NSW PH (4,000) NSW CH (750) and WA PH (600).
The over-sampling of lesser populated states and territories produced a sample that was not proportional to the jurisdiction/housing programs distribution of the social housing population. Weighting was applied to adjust for imbalances arising from execution of the sampling and differential response rates, and to ensure that the results relate to the social housing population.
The weighting for the 2014 survey was calculated as the number of households in each jurisdiction (population) divided by the number of usable surveys (responses). All population counts were provided by the AIHW.
The survey findings are based on self-reported data.
For the 2014 NSHS, caution should be used when comparing trend data or data between jurisdictions due to differences in response rates and non-sampling error.
The 2014 NSHS sampling and stratification methods were similar to the 2012 survey i.e. a sample was randomly selected of each jurisdiction’s PH, SOMIH and CH tenants. As requested by NSW stratified sampling by region/area was undertaken for NSW PH tenancies.
In 2014, the data collected for SOMIH was sourced using two methodologies (via mail-out in two jurisdictions and via face-to-face interview in two jurisdictions). Trend data and comparisons between jurisdictions should therefore be interpreted with caution.
Surveys in this series commenced in 2001. Over time, modifications have been made to the survey’s methodology and questionnaire design. As noted above, the sample design and the questionnaire of the 2014 survey differs in a number of important respects from previous versions of the survey.
Please refer to data quality statements and technical reports for the relevant surveys before comparing data across surveys.
