1 This publication presents results from the Australian Bureau of Statistics (ABS) Environmental Views and Behaviour Survey, conducted throughout Australia as part of the 2007-08 Multi-Purpose Household Survey (MPHS), a supplement to the monthly Labour Force Survey (LFS). This is the first time that data about environmental views and behaviour have been collected in the MPHS.
2 The Environmental Views and Behaviour Survey collected information from individuals aged 18 years and over about their views and practices on environmental issues, over a twelve month period from the date of interview. Of the 15,800 private dwellings surveyed for the MPHS, 13,527 persons responded to the Environmental Views and Behaviour Survey. After discounting private dwellings where 15-17 year old persons were interviewed, the estimated Environmental Views and Behaviour Survey response rate is 88%.
3 Further information about data collection is provided in the Section below on Data Collection.
4 The scope of the LFS is restricted to people aged 15 years and over (18 years and over for the Environmental Views and Behaviour Survey) who were usual residents of private dwellings, except:
5 The 2007-08 MPHS also excluded:
6 The 2007-08 MPHS was conducted in both urban and rural areas in all states and territories, but excluded people living in very remote parts of Australia. The exclusion of these people is expected to have only a minor impact on any aggregate estimates that are produced for individual states and territories, except the Northern Territory where such people account for around 23% of the population.
7 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. 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 the MPHS. It also contains definitions of demographic and labour force characteristics, and information about telephone interviewing relevant to both the monthly LFS and the MPHS.
8 The MPHS is conducted as a supplement to the monthly Labour Force Survey (LFS). One eighth of the LFS sample is rotated out of the survey each month, called the 'outgoing rotation group'. One third of the dwellings in this outgoing rotation group are selected for the MPHS. In each of these dwellings, after the LFS has been fully completed for each person in scope and coverage, a person (usual resident) aged 18 years and over is selected at random (based on a computer algorithm) and asked the additional MPHS Environmental Views and Behaviour questions in a personal interview. Data are collected using Computer Assisted Interviewing (CAI), whereby responses are recorded directly onto an electronic questionnaire in a notebook computer generally during a telephone interview.
Environmental Views and Behaviour
9 The usual MPHS sample is accumulated over a twelve month period (July 2007 to June 2008). Refer above to paragraph 2 in the Introduction for the final sample size.
RELIABILITY OF ESTIMATES
10 The estimates provided in this publication are subject to sampling and non-sampling error.
11 Sampling error is the difference between the published estimates, derived from a sample of persons, and the value that would have been produced if all persons in scope of the survey had been included. For more information refer to the Technical Note.
12 Non-sampling error may occur in any collection, whether it is based on a sample or a full count such as a census. Sources of non-sampling error included non-response, errors in reporting by respondents or recording of answers by interviewers, and errors in coding and processing data. Every effort is made to reduce the non-sampling error to a minimum by careful design of questionnaires, intensive training and supervision of interviewers and effective processing procedures.
IMPUTATION FOR NON-RESPONSE
13 Certain data items such as estimates of income had significant non-response for the 2007-08 MPHS. The ABS has not applied any imputation methodology for estimation of values for non-responses.
COMPARABILITY WITH MONTHLY LFS STATISTICS
14 Due to differences in the scope and sample size of the MPHS 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.
2007-2008 MPHS OUTPUTS
15 The MPHS is designed to collect statistics for a number of small, self-contained topics. These include both labour topics and other social and economic topics. The topics collected in 2007-08 were:
16 The MPHS also collects other socio-demographic information such as educational attainment, labour force status and personal and household income.
17 Data for other MPHS topics collected in 2007-08 is released in separate publications. In addition, data from the 2007-08 MPHS will be released as an expanded Confidentialised Unit Record File (CURF) in early 2009.
CONFIDENTIALISED UNIT RECORD FILE
18 Confidentialised Unit Record Files (CURF) release confidentialised microdata from surveys, thereby facilitating interrogation and analysis of data. For all MPHS topics covered in the 2007-08 survey, an expanded CURF will be available in 2009. For more information on expanded CURFs refer to ABS information paper Multi-Purpose Household Survey, Expanded Confidentialised Unit Record File, Technical Manual (cat. no. 4100.0).
19 ABS 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.
