Labour Statistics: Concepts, Sources and Methods was originally released in 2001 in both electronic and paper versions (cat. no. 6102.0). The paper publication will not be rereleased. However, the web version (cat. no. 6102.0.55.001) is being updated on an ongoing basis.
3.6 The notion of formal attachment applies only in respect of absences from jobs involving paid employment. Persons in self-employment who are 'with an enterprise but not at work' (i.e. temporarily absent from work for some specific reason) are considered employed. The international standards do not set out formal criteria for temporary absence from self-employment because of the diverse working patterns of the self-employed. However, guidelines for the self-employed recognise that the continued existence of the enterprise and an acceptable duration of absence (indicated, for example, by the reason for absence) may be sufficient. The treatment of absent contributing family workers in the guidelines is consistent with this view; as they are not considered to have an enterprise of their own, they cannot be 'with an enterprise but not at work', and should not be included among the employed.
DEFINITIONS USED IN ABS SURVEYS
3.7 The ABS produces estimates of employment from both household and business surveys. The definitions of employment used in household surveys are designed to be consistent with the international standards. The definition of employment used in business surveys relates more closely to paid employment.
DEFINITIONS USED IN ABS HOUSEHOLD SURVEYS
3.8 Three different definitions of employment are used in ABS household surveys. The Labour Force Survey is designed to produce precise estimates of employment (and unemployment), and the definition used aligns closely with international standards and guidelines. In other household surveys where employment is an explanatory variable or classificatory variable, it is generally not practical to determine employment as precisely as in the Labour Force Survey. While estimates of employment produced from these surveys are designed to be consistent with the international concept of employment, the definition used is slightly broader than that used in the Labour Force Survey. Two alternative questionnaire modules are used to produce estimates of employment in these surveys - a reduced questionnaire module (for use in personal interviews), and a self-enumerated questionnaire module.
Labour Force Survey
3.9 The definition of employment used in the Labour Force Survey aligns closely with the concepts and international definitions outlined above. Employed persons are defined as all persons 15 years of age and over who, during the reference week:
3.10 For employees absent from work, a condition of formal job attachment is considered to exist in any of the following circumstances:
3.12 Of the self-employed, employers and own account workers absent from work during the reference week are defined as employed without further testing of 'formal job attachment'. Contributing family workers who are absent from work in the reference week are not considered to be employed. This is consistent with the international guidelines discussed above.
Other ABS household surveys
3.13 Most other ABS household surveys use one of the two alternative questionnaire modules (the reduced questionnaire module used for personal interviews, or the self-enumerated questionnaire module) to produce employment estimates. As discussed above, employment is more broadly defined in these modules than in the Labour Force Survey:
3.14 Estimates of employment produced from the reduced questionnaire module for personal interviews are slightly higher (around 0.1%) than those produced from the Labour Force Survey. This results from differences in the treatment of persons temporarily away from work. In the reduced questionnaire module all persons away from work are classified as employed. In comparison, the Labour Force Survey classifies persons away from work as employed if:
3.15 The self-enumerated questionnaire module also produces different estimates of employment from the Labour Force Survey. Some differences result from the shortened set of questions, which cannot determine employment as precisely as the Labour Force Survey (as the latter uses a longer set of questions to determine whether persons are employed). The self-enumeration nature of the questions also causes some differences, due to differences in interpretation among respondents. As a result, employment estimates from the self-enumerated questionnaire module are best used as explanatory or classificatory variables to explain other phenomena, rather than for detailed analysis of the labour force itself.
DEFINITION OF EMPLOYMENT USED IN ABS BUSINESS SURVEYS
3.16 Concepts of employment used in ABS business surveys are narrower than the concept used in ABS household surveys. While estimates of employment from household surveys are of persons engaged in economic activity, estimates from business surveys are of jobs involving paid employment. There are two important distinctions between these estimates: the first relates to the statistical unit being measured, i.e. persons versus jobs; and the second to the concept being measured, i.e. (total) employment versus paid employment. These are discussed further below.
3.17 First, estimates of employment from business surveys refer to jobs rather than persons. For example persons holding jobs with different employers would be counted in ABS household surveys as employed once, but in ABS business surveys would be counted once for each job held.
3.18 Second, estimates of employment from business surveys mainly relate to paid employment. Paid employment is a component of total employment; when combined with self-employment, it would provide a concept of employment that is consistent with the international concepts. However, the coverage of paid employment applied in ABS business surveys is narrower than that outlined in the international guidelines. It excludes:
3.19 Some industry and economy-wide ABS business surveys, however, do include a component of self-employment as well as paid employment in their surveys. For example, working proprietors and partners are included in the Economic Activity Survey.
3.20 Estimates of the number of paid employment jobs (also referred to as employee jobs) from ABS business surveys are most commonly compared to estimates of the number of persons in paid employment jobs (also referred to as employees) from ABS household surveys. However, estimates of employees from household surveys are not equivalent to estimates of employee jobs from business surveys and, when comparing estimates, the differences outlined above should be considered. Conceptual and methodological reasons for differences between estimates of employees from the Labour Force Survey and estimates of employee jobs from the Survey of Employment and Earnings (a business survey) are discussed in the ABS Information Paper: Comparison of Employment Estimates from the Labour Force Survey and the Survey of Employment and Earnings (cat. no. 6263.0).
3.21 Estimates of employment are available from the following ABS household surveys:
3.22 Estimates of employee jobs are produced from the following ABS business surveys:
LABOUR FORCE SURVEY
3.23 The monthly Labour Force Survey is the official source for Australian employment and unemployment statistics. The definition of employment used in the Labour Force Survey is outlined above. The survey uses a comprehensive and detailed set of questions to precisely measure the numbers and certain characteristics of persons in employment and unemployment as well as persons not currently economically active. Estimates from the Labour Force Survey are available by State/Territory, capital city/rest of State, and 67 sub-State regions (see Chapter 16 for more information on geographic classifications available from ABS household surveys). For more detail on the content and methodology of the Labour Force Survey see Chapter 20.
CENSUS OF POPULATION AND HOUSING
3.24 As discussed above (paragraphs 3.13-3.15), the Census of Population and Housing uses the self-enumerated questionnaire module to produce employment estimates consistent with the international standards. However, because the self-enumerated questionnaire module defines employment less precisely than the Labour Force Survey, estimates produced are not strictly comparable with those from the Labour Force Survey. For these reasons, employment estimates from the Census should be used with caution in analyses where labour force activities are a major focus. When comparing estimates of employment from the Census of Population and Housing with those produced from the Labour Force Survey, users should also note differences between the two surveys in scope (for example, the inclusion of permanent defence forces in Census employment data) and methodology. Employment estimates from the Census are available down to the statistical local area level (footnote 1). Refer to Chapter 19 for further information on the Census of Population and Housing.
SPECIAL SOCIAL SURVEYS
3.25 As discussed above (paragraphs 3.13-3.15), most Special Social Surveys use the reduced questionnaire module for personal interviews to produce employment estimates that are consistent with the international standards. However, because the reduced questionnaire module defines employment less precisely than the Labour Force Survey, estimates produced are not strictly comparable with those produced from the Labour Force Survey. When comparing employment estimates from Special Social Surveys with estimates from the Labour Force Survey, users should also note differences in scope and methodologies across the surveys.
3.26 The labour-related Special Social Surveys - the Survey of Employment Arrangements and Superannuation (Chapter 23) and the Survey of Employment and Unemployment Patterns (Chapter 24) - both produced estimates of employment. Unlike most Special Social Surveys, neither of these surveys used the reduced questionnaire module to produce measures of employment as described above. Instead, both surveys used questions asked in the Labour Force Survey. However, the questions used in the Survey of Employment Arrangements and Superannuation were modified slightly from those used in the Labour Force Survey and collected information about two jobs where appropriate. For more information on these surveys, refer to the chapters listed above.
SURVEY OF EMPLOYMENT AND EARNINGS
3.27 The Survey of Employment and Earnings is a business survey producing estimates of employee jobs. There are conceptual reasons (as discussed in paragraphs 3.16-3.20) as well as methodological reasons for differences in estimates of employment produced from business and household surveys. For further information on the scope and collection methodology of this survey refer to Chapter 31.
ECONOMIC ACTIVITY SURVEY
3.28 The Economic Activity Survey is a business survey producing employment estimates. There are conceptual as well as methodological reasons for differences in estimates of employment produced from business and household surveys. For further information on the scope and collection methodology of this survey refer to Chapter 33.

1. Statistical local areas (SLAs) consist of one or more Census collection districts. In aggregate, SLAs cover the whole of Australia without gaps or overlaps. An SLA consists of a single local government area, or part thereof, or any unincorporated area. For further information refer to Chapter 16 <back
