EXPLANATORY NOTES


INTRODUCTION

1 The statistics in this publication were compiled from data collected in the Queensland Water and Energy Use and Conservation Survey that was conducted in Queensland in October 2009 as a supplement to the Australian Bureau of Statistics (ABS) monthly Labour Force Survey (LFS). The major aim of the survey was to collect data on how households use and conserve water and energy.

2 The publication Labour Force, Australia (cat. no. 6202.0) contains information about survey design, sample redesign, scope, coverage and population benchmarks relevant to the monthly LFS, which also applies to supplementary surveys. It also contains definitions of demographic and labour force characteristics, and information about telephone interviewing.


SCOPE

3 The scope of this supplementary survey was restricted to people aged 18 years and over who were usual residents of private dwellings and excludes the following:

  • members of the Australian permanent defence forces
  • certain diplomatic personnel of overseas governments, customarily excluded from censuses and surveys
  • overseas residents in Australia
  • members of non-Australian defence forces (and their dependents)
  • residents of other non-private dwellings such as hospitals, hotels and motels
  • people living in very remote areas.

4 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.

5 The exclusion of people living in very remote areas will have only a minor impact on any aggregate estimates.


COVERAGE

6 The estimates in this publication relate to households covered by the survey in October 2009. In the LFS, coverage rules are applied 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.


METHODOLOGY

Concepts, sources and methods

7 More information about the Labour Force Survey and Labour Force supplementary surveys can be found in Labour Statistics: Concepts, Sources and Methods (cat. no. 6102.0.55.001) which is available on the ABS website <http://www.abs.gov.au>. Comprehensive discussion and description of the concepts and definitions underpinning Australian labour statistics and the data sources and methods used in the collection and compilation of these statistics are included.

Data collection

8 Information was collected from any responsible adult (ARA) in the household who was asked to respond on behalf of the household and on behalf of the randomly selected person aged 18 years and over for questions regarding public transport usage.

9 Information was sought from 4,230 private dwellings, of which 96.8% fully responded.

Survey Vehicle

10 The Labour Force Survey is based on a multi-stage area sample of private dwellings (houses, flats, etc.) and a list sample of non-private dwellings (hotels, motels, etc.).

11 This supplementary survey comprised a series of additional questions asked at the end of each Labour Force Survey interview. The interviews were conducted over a two-week period during October 2009.

12 Most interviews were conducted by telephone, with the remainder conducted face-to-face.

Estimation

13 The estimation process for this survey ensures that estimates calibrate exactly to independently produced population totals at broad levels. The known population totals, commonly referred to as 'benchmarks', are produced according to the scope of the survey. The same is true for estimates of households produced in this survey. However, in these cases the household benchmarks are actually estimates themselves and not strictly known population totals.


LABOUR FORCE REGIONS

14 The Labour Force Statistical Regions used within this publication are based on the 2006 Australian Standard Geographical Classification system. For further information please see Chapter 5 Statistical Region Structure in the Statistical Geography Volume 1 - Australian Standard Geographical Classification (ASGC), Jul 2006 (cat. no. 1216.0).

15 It is this classification that details the regions within Queensland, for example the Brisbane City Inner Ring and the Brisbane City Outer Ring.


DATA COMPARABILITY

16 Time series comparisons between the Queensland Water and Energy Use and Conservation Survey and the national environmental publications (listed below) are not recommended due to differences in sampling methodologies.
RELIABILITY OF THE ESTIMATES

17 Estimates in this publication are subject to sampling and non-sampling errors. For further information refer to the Technical Note.


ACKNOWLEDGEMENTS

18 ABS surveys draw extensively on information provided 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.


ROUNDING

19 Estimates have been rounded so discrepancies may occur between sums of the component items and totals. Published percentages are calculated prior to rounding of the figures and therefore some discrepancy may occur between these percentages and those that could be calculated from the rounded figures.
