QUALITY DECLARATION - SUMMARY


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.

Confidentialised Unit Record Files (CURFs) and TableBuilder files are released in accordance with the conditions specified in the Statistics Determination section of the Census and Statistics Act 1905. This ensures that confidentiality is maintained whilst enabling micro level data to be released. More information on the confidentiality practices associated with CURFs can be found on the About CURF Microdata page. More information on the confidentiality practices associated with TableBuilder can be found on the Confidentiality page of the User Manual: TableBuilder.

Relevance

Microdata from the 2014–15 National Aboriginal and Torres Strait Islander Social Survey (NATSISS) provides information on a range of demographic, social, environmental and economic indicators, including: personal and household characteristics; geography; language and cultural activities; social networks and support; health and disability; education; employment; stressors; income; housing; and crime, law, and justice. Information from the NATSISS contributes to existing data on Aboriginal and Torres Strait Islander people and the formulation of government policies and legislation.

This is the fourth social survey of Aboriginal and Torres Strait Islander Australians conducted by the ABS. The previous surveys were conducted in 2008 and 2002, and the first survey, the National Aboriginal and Torres Strait Islander Survey (NATSIS), was conducted in 1994.

The level of detail provided for selected data items are available within the Data Item List in the Downloads page.

Timeliness

Data from the survey are released within twelve months of the completion of enumeration.


Accuracy

The NATSISS was designed to produce reliable estimates at the national and state/territory levels, as well as by remoteness at the national level.

Estimates from the NATSISS are subject to sampling and non-sampling errors. Information on sampling and non-sampling errors is provided in the Technical Note in the summary publication.

Microdata contains finer levels of detail of data items than what is otherwise published in other formats. For more information on the level of detail provided, please see the Data Item List in the Downloads page of this product.

Steps to confidentialise microdata are taken in such a way as to maximise the usefulness of the content while maintaining the confidentiality of respondents selected in the survey. As a result it may not be possible to exactly reconcile all the statistics produced from the microdata with other published statistics. Further information about the steps taken to confidentialise the microdata is available through the following links:
