Institutional environment:![]() | For information on the institutional environment of the Australian Bureau of Statistics (ABS), including the legislative obligations of the ABS, financing and governance arrangements, and mechanisms for scrutiny of ABS operations, please see ABS Institutional Environment. |
Timeliness:![]() | Survey of Income and Housing (SIH) The biennial SIH is enumerated over a twelve month period to account for seasonal variability in its measures. Results for 2007-08 were released in August 2009. National Aboriginal and Torres Straist Islander Social Survey (NATSISS) The NATSISS is conducted every six years. The 2008 NATSISS was conducted from August to April 2008. Results from the 2008 survey were released in October 2009. |
Accessibility:![]() | The unit record data used to compile this measure are available to other users through the Confidentialised Unit Record File (CURFs) released by ABS. |
Interpretability:![]() | Information is available for both collections to aid interpretation of the data. See the Survey of Income and Housing User Guide and Explanatory Notes in National Aboriginal and Torres Strait Islander Social Survey 2008 on the ABS web site. The 2008 NATSISS Users’ Guide will be released in 2010. |
Relevance:![]() | Survey of Income and Housing (SIH) The SIH collects data on tenure from usual residents of private dwellings in Australia. Owners (i.e households that own their dwelling outright, have a mortgage outstanding on their dwelling or are in a rent-buy or shared equity scheme) are separately identified. Disaggregation is provided for several geographic and socio-demographic variables. The SIH excludes the 0.8 per cent of the Australian population living in very remote areas. This exclusion impacts on comparability of data for the Northern Territory, where these people are around 23 per cent of the population. As a consequence of this exclusion, comparisons between Indigenous and non-Indigenous households in remote areas are not available. Household disability status cannot be obtained from the 2007-08 SIH. It will be available from the 2009-10 survey. National Aboriginal and Torres Strait Islander Social Survey (NATSISS) An Indigenous household is a household where at least one usual resident of any age identifies as being of Aboriginal or Torres Strait Islander origin. In the NATSISS, an adult provides information on tenure, which separately identifies households that are owners with and without a mortgage. In the 2008 NATSISS, household income was either not stated or not known for 19 per cent of households. Therefore income quintiles are based on the 81 per cent of households for which this information was available. The 2008 NATSISS did not collect information on: a reference person; dwelling type; household income type; the number of employed persons in the household. |
Accuracy:![]() | Survey of Income and Housing (SIH) The total sample take in 2007-08 was 9345 households, with a response rate was 84.0 per cent. Most of the non-response was due to householders that were not able to be contacted, and only one-sixth of the non-response was due to households refusing to participate in the survey. To account in part for non-response, SIH data are weighted by: state, part of state, age, sex, labour force status, number of households and household composition. At the national level this Performance Indicator for 2007-08 has a relative standard error (RSE) of less than 1 per cent. RSEs are higher for state and territory measures, and for other disaggregations. In 2009-10 the SIH sample has been doubled to 18 000 households. While this will reduce national RSEs on average by 30 per cent, the improvements will be larger for estimates for some of the smaller states and territories. National Aboriginal and Torres Strait Islander Social Survey (NATSISS) The NATSISS is conducted in all states and territories and includes remote and non-remote areas. The 2008 sample was 13 300 persons/6900 households, with a response rate of 82 per cent of households. In the absence of a comprehensive sampling frame, the 2008 NATSISS adopted a screening approach for locating its target population (compared to the more common approach of using a dwelling from for general population surveys). Potential bias due to undercoverage in this screening approach was addressed by the application of adjustments to the initial weights, including adjustment based on the density of the Indigenous population in different areas. As undercoverage can result in variances across population characteristics, as well as across data items, caution should be exercised when interpreting the survey results. For more information see the 2008 NATSISS Quality Declaration. Overall, this indicator has an RSE of 4 per cent at the national level, and between 5 per cent and 12 per cent for each state or territory. Finer levels of disaggregation (e.g. by the inclusion of other cross classifying variables) may result in higher levels of sampling error. |
Coherence:![]() | The data items used to construct the measures are consistent between cycles within each data source and support assessment of change over time. While there are a range of differences in the scope, coverage, timing and collection methodologies of the SIH and the NATSISS, these issues do not affect their broad consistency for this measure. |
