Institutional environment:Help on this term

The Census of Population and Housing ('the Census') is collected by the Australian Bureau of Statistics (ABS) under the Census and Statistics Act 1905.

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

Timeliness:Help on this termThe Census is conducted every five years in August. Results from the 2011 Census are being released in three phases – two took place on 21 June and 30 October 2012; the release of highly specialised products will take place progressively in 2013.

Interpretability:Help on this term

The 2011 Census Dictionary (ABS cat. no. 2901.0) is a comprehensive reference guide designed to assist users to determine and specify their data requirements, and to understand the concepts underlying the data. It provides details of classifications used and a glossary of definitions of Census terms.

A number of other resources can be accessed from the Data quality page, including data quality statements for these data items and Fact sheets.

Tables describing the population of Indigenous and non-Indigenous persons included in and excluded from this indicator, in both 2006 and 2011, are available via this link.

Relevance:Help on this term

Census data are available by state/territory and by statistical areas. The Census collects data from all people in Australia on Census night, except foreign diplomats and their families. Norfolk Island is outside the scope of the Census.

The Census collects information on the highest year of school completed and highest level of non-school qualification for each individual aged 15 and over. The classification of qualifications used is the Australian Standard Classification of Education (ASCED) (ABS cat. no. 1272.0).

Accuracy:Help on this term

The 2011 Post Enumeration Survey, which is run by the ABS a month after each Census is completed, found a net undercount for the 2011 Census of 1.7 per cent. This means over 98 per cent of all people in Australia on Census night were counted; this was an improvement of 1 per cent on the undercount from 2006. The Census is self-enumerated; respondents sometimes do not return a Census form or fail to answer every applicable question. While some data is imputed, the majority of output classifications include a 'Not Stated' category to record the level of non-response for that data item.

This indicator uses two Census data items – 'Highest Year of School Completed' (for Year 12) and 'Non-School Qualification: Level of Education' (for AQF Certificate level II or above). Non-response rate for 'Highest Year of School Completed' in the 2011 Census was 8.4 per cent (down from 9.9 per cent in 2006). An estimated 1 per cent of responses were incorrect; in these cases responses are accepted in the order they appear on the form and extra responses are rejected. 'Non-response rate for the Non-School Qualification: Level of Education' variable in the 2011 Census was 2.6 per cent (down from 3.8 per cent in 2006).

The 'Indigenous Status' item is used to ascertain the Indigenous status of persons. The non-response rate for this variable was 4.9 per cent (down from 5.7 per cent in 2006). Additional data on not stated responses for this indicator by 'Indigenous Status' for 2006 and 2011 are provided in the Appendix tables below. For further information see specific data quality statements and the non-response rate quality statement.

Coherence:Help on this term

It is important for Census data to be comparable and compatible with previous Censuses and also with other data produced by the ABS and wider community. The ABS, and the Census, uses Australian standard classifications, where available and appropriate, to provide data comparability across statistical collections.

The Australian Standard Classification of Education (ASCED) (ABS cat. no. 1272.0) 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 National Aboriginal and Torres Strait Islander Social Survey, National Aboriginal and Torres Strait Islander Health Survey and Survey of Education and Work (ABS cat. no. 6227.0) and the Survey of Learning and Work (ABS cat. no. 4235.0) also provide information on educational attainment for this indicator.
