Data quality

Institutional environment:

The National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) and Survey of Education and Work (SEW) were collected, processed and published by the Australian Bureau of Statistics (ABS). The ABS operates within a framework that includes the Census and Statistics Act 1905 and the Australian Bureau of Statistics Act 1975. These ensure the independence from political influence and impartiality of the ABS and the confidentiality of respondents.

For more information on the institutional environment of the ABS, including the legislative obligations of the ABS, financing and governance arrangements, and mechanisms for scrutiny of ABS operations, see ABS Institutional Environment.

Timeliness:

The NATSIHS is conducted approximately every six years. The 2018‑19 NATSIHS was conducted between July 2018 to April 2019. Previous NATSIHS was collected in 2012-13 and 2004-05. Results from the 2018‑19 NATSIHS were released in December 2019.

The SEW is conducted annually in May as a supplement to the monthly Labour Force Survey (LFS). Results from the 2018 survey were released in November 2018.

Accessibility:

See National Aboriginal and Torres Strait Islander Health Survey, 2018‑19 (ABS 2019) and Education and Work, Australia, May 2018 (ABS 2018a) for an overview of results.

Data from these surveys are also be accessible in the DataLab and TableBuilder environment. For further details, refer to the Microdata Entry Page on the ABS website.

Other information from these surveys may also be available on request from the ABS.

Interpretability:

Information to aid interpretation of the data is available from the National Aboriginal and Torres Strait Islander Health Survey, 2018-19 (ABS 2019) and Education and Work, Australia, May 2018 (ABS 2018).

Relevance:

The NATSIHS and SEW collects information on level of highest non-school qualification and level of current study. The classification of qualifications used is the Australian Standard Classification of Education (ASCED) 2001 (ABS 2001).

For some respondents, information is supplied by another household resident (referred to as 'Any Responsible Adult'), such as a parent, partner or unrelated adult. While this is a standard survey methodology, answers to some questions may occasionally differ from those that would have been supplied in a personal interview.

While Indigenous status is collected in the SEW, the survey sample and methodology are not designed to provide output that separately identifies Aboriginal and/or Torres Strait Islander people. The SEW can, however be used for providing non-Indigenous comparisons.

Accuracy:

The NATSIHS was conducted in all states and territories, including very remote areas. Non-private dwellings such as hotels, motels, hospitals, nursing homes and short-stay caravan parks were excluded from the survey. The final response rate was 73.4%. Results are weighted to account for non-response.

The SEW was conducted in all states and territories, including very remote areas (except discrete Indigenous communities). The scope of the SEW is restricted to persons aged 15-74 years who were usual residents of private dwellings. The 2018 SEW response rate was 92% from the Monthly Population Survey. The data for the SEW are collected from an Any Responsible Adult on behalf of other members of the household and are weighted for nonresponse.

As they are drawn from a sample survey, data for the indicator are subject to sampling error. Sampling error occurs because only a small proportion of the population is used to produce estimates that represent the whole population. Sampling error can be reliably estimated as it is calculated based on the scientific methods used to design surveys. Rates should be considered with reference to their Relative Standard Error (RSE). Estimates with RSEs between 25% and 50% should be used with caution. Estimates with RSEs greater than 50% are generally considered too unreliable for general use.

Proportions should be considered with reference to their corresponding 95% margin of error (MOE) of proportion (or 95% confidence interval). The proportion combined with the MOE of proportion defines a range which is expected to include the true population value with a given level of confidence. This is known as the confidence interval. Proportions with an MOE of proportion greater than 10 percentage points indicate that the range in which the true population value is expected is relatively wide and are subject to high sample variability. Particular consideration should be given to the MOE of proportion when using them. Depending on how the proportion is to be used, an MOE of proportion greater than 10 percentage points may be considered too large to inform decisions. In addition, proportions with a corresponding standard 95% confidence interval that includes 0% or 100% are usually considered unreliable for most purposes.

Coherence:

Both the numerator and the denominator for Aboriginal and Torres Strait Islander persons come from the NATSIHS. Measures based on the 2018-19 NATSIHS are consistent with those supplied from previous cycles of this survey.

Both the numerator and denominator for non-Indigenous persons come from the SEW. Measures based on the 2018 SEW are consistent with those supplied from previous cycles of this survey.

The SEW excludes people living in Indigenous communities. Since 2009, SEW has included people living in 'very remote' areas who are not in Indigenous communities. Prior to SEW 2009, all persons living in 'very remote' parts of Australia were excluded.

Persons who are permanently unable to work were included in the scope of SEW for the first time in 2013. There were an estimated491,170 people who reported being permanently unable to work in May 2014.

The ASCED has been used in all surveys with education items since 2001 and allows the education and training items between different surveys to be compared.

The Census of Population and Housing and the Survey of Qualifications and Work (ABS 2016) also provide information on educational attainment.

The data items used to construct the measures in the NATSIHS and the SEW are consistent and comparable, and support assessment of change over time. While there are a range of differences between the scope, coverage, timing and collection methodologies of the collections, these issues do not affect their broad consistency for this measure.
