5 Students at boarding schools, patients in hospitals, residents of homes (e.g. retirement homes, homes for people with disabilities), and inmates of prisons are excluded from all supplementary surveys.
6 This supplementary survey was conducted in both urban and rural areas in all states and territories but excluded people living in Indigenous communities in very remote parts of Australia.
7 The estimates in this publication relate to people covered by the survey in September 2009. In the LFS, coverage rules are applied which aim to ensure that each person is associated with only one dwelling and hence has only one chance of selection in the survey. See Labour Force, Australia (cat. no. 6202.0) for more details.
8 Supplementary surveys are not always conducted on the full LFS sample. Since August 1994, the sample for supplementary surveys has been restricted to no more than seven-eighths of the LFS sample.
9 The LFS sample size in September 2009 was approximately 9% higher than the sample size in September 2008. This is due to re-instated sample that was cut from the Labour Force Survey (LFS) and supplementary surveys from July 2008. Detailed information about the sample reduction/re-instatement is provided in Information Paper: Labour Force Survey Sample Design, Nov 2007 (Third edition) (cat. no. 6269.0).
10 The re-instated sample will still be representative, with selections made across all parts of Australia.
11 The initial sample for the September 2009 LFS consisted of 29,283 private dwelling households and special dwelling units. Of the 23,512 private dwelling households and special dwelling units that remained in the survey after sample loss (e.g. households selected in the survey which had no residents in scope for the LFS, vacant or derelict dwellings and dwellings under construction), approximately 22,362 or 95.1% were fully responding to the Underemployed Workers Survey. The number of completed interviews obtained from these private dwelling households and special dwelling units (after taking into account scope, coverage and subsampling exclusions) was 24,376.
RELIABILITY OF THE ESTIMATES
12 Estimates in this publication are subject to sampling and non-sampling errors:
13 The estimates are based on information collected in the survey month and, due to seasonal factors, may not be representative of other months of the year.
14 Country of birth data are classified according to the Standard Australian Classification of Countries (SACC), 2008 (cat. no. 1269.0).
15 Educational attainment data are classified according to Australian Standard Classification of Education (ASCED) (cat. no. 1272.0).
COMPARABILITY OF TIME SERIES
16 In September 2008 there was a substantial increase in the number of part-time workers who preferred more hours and underemployed workers. This was due to a change in the question being asked of part-time workers. From September 2008, part-time workers were asked "Would you prefer to work more hours than you usually work?". In previous surveys part-time workers were asked "Would you prefer a job in which you worked more hours a week?". The question was altered to be consistent with the LFS and is now broader and more inclusive of people's situations as it relates to a preference for more hours of work.
17 This change contributed to an additional 115,800 people who were classified as part-time workers who preferred more hours and an additional 131,500 people who were classified as underemployed workers in 2008. Users need to exercise care when comparing the number of part-time workers who preferred more hours and underemployed workers from 2008 onwards with previous releases because of this break in series.
18 From July 2004, a change was made to the category 'considered too young or too old by employers' for the items 'all difficulties in finding work with more hours' and 'main difficulty in finding work with more hours'. The category has been split into 'considered too young by employers' and 'considered too old by employers'.
19 Revisions are made to population benchmarks for the LFS after each five-yearly Census of Population and Housing. The last such revision was made in February 2009 to take account of the results of the 2006 Census of Population and Housing. Estimates from supplementary surveys conducted from and including February 2009 are based on these 2006 population benchmarks.
20 Prior to September 1994, part-time workers who would prefer more hours of work were asked whether they were available to start work with more hours within the subsequent four weeks. From September 1994, an additional question was added to determine their availability to start work with more hours during the reference week. This question was added to the survey so that estimates of underemployment could be more easily aligned with the then current International Labour Organisation (ILO) recommendations on underemployment.
21 As part of the 2001 LFS questionnaire redesign, people who were on short-term unpaid leave initiated by the employer, are now classified as employed. This approach is consistent with ILO recommendations on formal job attachment. Analysis of data from the LFS shows that many of these people usually worked part time, and that a number of these had a preference to work more hours. However, overall, these people contribute only marginally to the change in part-time workers who would prefer more hours.
COMPARABILITY WITH MONTHLY LFS STATISTICS
22 Due to differences in the scope and sample size of this supplementary survey and that of the monthly LFS, the estimation procedure may lead to some small variations between labour force estimates from this survey and those from the monthly LFS.
COMPARABILITY WITH ILO GUIDELINES
23 The ABS definition of underemployment is consistent with the International Labour Organisation (ILO) guidelines of time-related underemployment adopted in 1998. According to these guidelines, time-related underemployment exists when the hours of work of an employed person are below a threshold, and are insufficient in relation to an alternative employment situation in which the person is willing and available to engage. More specifically, people in time-related underemployment comprise all employed people (as defined) who satisfy the following three criteria:
24 A more detailed discussion is included in Labour Statistics: Concepts, Sources and Methods (cat. no. 6102.0.55.001), Chapter 5.
25 The Underemployed Workers Survey was conducted in May 1985, 1988 and 1991. In 1994, the survey became an annual survey, collected each September. Results of previous surveys were published in: Underemployed Workers, Australia (cat. no. 6265.0); and the standard data service Underemployed Workers, Australia (cat. no. 6265.0.40.001) for 1994 and 1995.
26 The ABS plans to conduct this survey again in September 2010.
27 The ABS draws extensively on information provided freely by individuals, businesses, governments and other organisations. Their continued cooperation is very much appreciated: without it, the wide range of statistics published by the ABS would not be available. Information received by the ABS is treated in strict confidence as required by the Census and Statistics Act 1905.
28 ABS publications which may be of interest include:
29 Current publications and other products released by the ABS are available free of charge from the Statistics Page on the ABS website. The ABS also issues a daily Release Advice on the web site which details products to be released in the week ahead.
