4 This supplementary survey also excluded people living in special dwellings (such as hotels, university residences, students at boarding schools, patients in hospitals, residents of homes (e.g. retirement homes, homes for persons with disabilities), and inmates of prisons).
5 This supplementary survey was conducted in both rural and urban areas in all states and territories of Australia, but excluded people living in very remote parts of Australia. The exclusion of these people will have only a minor impact on any aggregate estimates that are produced for individual states and territories, with the exception of the Northern Territory where such persons account for about 19% of the population.
6 The estimates in this publication relate to households covered by the survey in March 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.
7 The response rate for the survey was 97%. In total, information was collected from 9,422 persons aged 18 years and over, and 9,362 households.
8 Information was collected through interviews conducted over a two-week period during March 2009. Information was collected from any responsible adult in the household aged 18 years and over who was asked to respond on behalf of the household for the waste management and motor vehicle ownership topics and for a randomly selected person in the household for the transport use topic.
9 Data was collected on the randomly selected person's use of transport on their usual trip to work, full-time study or day-to-day travel. Data on motor vehicle usage relates to details on the number of registered motor vehicles kept at the home and the vehicle driven most often, and includes details on use and ownership in the last 12 months. Information was also collected on bicycle ownership. Data on waste management relates to the recycling and re-using of household waste in the last 12 months.
RELIABILITY OF THE ESTIMATES
10 Estimates in this publication are subject to sampling and non-sampling errors.
11 Sampling error is the difference between the published estimate and the value that would have been produced if all dwellings had been included in the survey. For further information refer to the Technical Note.
12 Non-sampling errors are inaccuracies that occur because of imperfections in reporting by respondents and interviewers, and errors made in coding and processing data. These inaccuracies may occur in any enumeration, whether in a full count or a sample survey. Every effort is made to reduce the non-sampling error to a minimum by the careful design of questionnaires, intensive training and supervision of interviewers and efficient data processing procedures.
13 A set of changing environment supplementary survey topics rotate over a period of three years. Previously these have been released in the same publication Environmental issues: People's Views and Practices (cat. no. 4602.0).
14 From 2008 the three separate topics under Environmental issues: People's Views and Practices (cat. no. 4602.0) are now three separate publications with different catalogue numbers. The 2009 publication is now titled Environmental Issues: Waste Management and Transport Use (cat.no. 4602.0.55.002). The information contained in this publication compare with most of the data collected in 1996, 2000, 2003 and 2006. Where applicable, the data have been included in this publication for comparison.
CHANGES IN THIS ISSUE
15 While the ABS seeks to maximise consistency and comparability over time by minimising changes to the survey; sound survey practise requires ongoing development to maintain the integrity of the data. A few minor changes were made to the survey between 2006 and 2009. These changes are outlined below.
16 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.
17 The ABS plans to conduct this survey again in March 2012.
