6 Students at boarding schools, patients in hospitals, residents of homes (e.g. retirement homes, homes for persons with handicaps), and inmates of prisons are excluded from all supplementary surveys.
7 This supplementary survey was conducted in both urban and rural areas in all states and territories, but excluded approximately 80,000 persons living in remote and sparsely settled parts of Australia who would otherwise have been within the scope of the survey. The exclusion of these persons will have only a minor impact on any aggregate estimates that are produced for individual states and territories, except the Northern Territory where such persons account for over 20% of the population.
8 Persons aged 70 years and over were also excluded from this survey.
9 The estimates in this publication relate to persons covered by the survey in September 2002. 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. 6203.0).
RELIABILITY OF THE ESTIMATES
10 Estimates in this publication are subject to sampling and non-sampling errors:
11 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.
12 Occupation data are classified according to the ASCO - Australian Standard Classification of Occupations, Second Edition, 1997 (cat. no. 1220.0).
13 Country of birth data are classified according to the Standard Australian Classification of Countries (SACC), 1998 (cat. no. 1269.0).
REVISION TO HISTORICAL DATA
14 Historical estimates of the civilian population for reference periods 1996 to 1999 were revised in the 2000 publication to exclude institutionalised persons, sparsely settled and remote parts of Australia.
COMPARABILITY OF TIME SERIES
15 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 1999 to take account of the results of the 1996 Census of Population and Housing. Estimates from supplementary surveys conducted from and including February 1999 are therefore based on revised population benchmarks.
16 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. Since it was introduced, this survey has been conducted on various proportional samples. Therefore, sampling errors associated with previous surveys may vary from the sampling error for this survey.
17 Persons Not in the Labour Force Surveys conducted up to and including September 1987 included all persons aged 15 years and over. From September 1988, the survey excluded all persons aged 70 years and over.
18 Comparability of 2002 and 2001 estimates with previous years, for persons who wanted to work, including discouraged jobseekers, may have been affected by the following:
COMPARABILITY WITH MONTHLY LFS STATISTICS
19 Due to differences in the scope and sample size of this supplementary survey and that of the LFS, the estimation procedure may lead to some small variations between labour force estimates from this survey and those from the LFS.
20 The difference between the estimates appearing in this publication and Labour Force, Australia (cat. no. 6203.0) is chiefly the result of excluding persons aged 70 years and over from the sample of this supplementary survey. Over one-quarter (30%) of the civilian population aged 15 years and over who were not in the labour force were excluded from answering questions from this supplementary survey because they were aged 70 years and over.
21 Core LFS series from April 1986 to March 2001 have been revised on the basis of the redesigned LFS questionnaire. Supplementary survey data have not been revised.
22 Further information on persons not in the labour force is available in Labour Force, Australia (cat. no. 6203.0). Note that such information refers to all persons aged 15 years and over.
23 The Persons Not in the Labour Force Survey was first conducted in May 1975 and again in May 1977. From 1979 to 1987 the survey was collected twice a year (March and September). Since then it has been conducted annually. Results of previous surveys were published in:
24 The ABS will conduct this survey again in September 2003.
25 Australian Bureau of Statistics publications draw 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.
