6 The coverage of the survey was the same as the scope except that the following populations were not enumerated for operational reasons:
7 The estimates in this publication relate to persons covered by the survey. In the LFS, coverage rules are applied which aim to ensure that each child is associated with only one dwelling, and hence have only one chance of selection in the survey. See Labour Force, Australia (cat. no. 6202.0) for more details.
8 Information was collected from any responsible adult in the household who was asked to respond on behalf of the children in the household. In each selected household, information on cultural, sporting and selected recreational activities was sought for a maximum of three children. The response rate for the survey was approximately 96%. In total, fully responding records were collected about the activities of 7,300 children living in the selected households. In households with four or more children aged 5-14 years, three children were randomly selected for the survey. For the additional children in these households only selected demographic information was collected.
9 Data were collected on children's cultural and sporting activities undertaken outside of school hours over a 12 month period. Data on the frequency of participation relates to the 12 months before interview, while data on the number of hours of participation refers to the last two weeks of school (the most recent two school weeks prior to the interview, including weekends and public holidays). School weeks are weeks during the school term (i.e. not school holidays) including weekends and public holidays. Data were also collected on children's participation in selected recreational activities during the last two weeks of school.
10 In a small number of households where a child was not living with a parent, information on the country of birth of parent and employment status of parent was collected for the person aged 15 years or over living in the household who was most closely related to the child.
11 All interviews were conducted using computer assisted interviewing (CAI) over a two week period during April 2012.
12 Supplementary surveys are not always conducted using 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.
13 Weighting is the process of adjusting results from a sample survey to infer results for the total population. To do this a 'weight' is allocated to each enumerated person. The weight is a value which indicates how many persons in the population are represented by the sample person. The first step in calculating weights for each unit is to assign an initial weight, which is the inverse of the probability of the unit being selected in the survey. For example, if the probability of a person being selected in the survey was 1 in 300, then the person would have an initial weight of 300 (that is, they represent 300 people).
14 The initial weights are then calibrated to align with independent estimates of the population, referred to as benchmarks. The population included in the benchmarks is the survey scope. This calibration process ensures that the weighted data conform to the independently estimated distribution of the population described by the benchmarks rather than to the distribution within the sample itself. Calibration to population benchmarks helps to compensate for over or under-enumeration of particular categories of persons which may occur due to either the random nature of sampling or non-response.
15 The survey was benchmarked to the estimated resident population (ERP) in each state and territory at April 2012 subject to scope exclusions as outlined above.
16 Survey estimates of counts of persons are obtained by summing the weights of persons with the characteristic of interest.
RELIABILITY OF THE ESTIMATES
17 All sample surveys are subject to error which can be broadly categorised as either sampling error or non-sampling error.
18 Sampling error is the difference between the published estimates, derived from a sample of children, and the value that would have been produced if all children in scope for the survey had been included. For more information refer to the Technical Note.
19 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 include non-response, errors in reporting by respondents or recording answers by interviewers, and errors in coding and processing data. Every effort was made to reduce the non-sampling error by careful design and testing of the questionnaire, training and supervision of interviewers, follow-up of respondents, and extensive editing and quality control procedures at all stages of data processing.
20 Information recorded in this survey is essentially ‘reported’ by respondents and hence may differ from that which might be obtained from other sources or via other methodologies. This factor should be considered when interpreting the estimates in this publication.
21 The Children's Participation in Cultural and Leisure Activities Survey was previously conducted in 2000, 2003, 2006 and 2009 as supplements to the Labour Force Survey. Computer assisted telephone interviewing was introduced during 2003 and while information was collected using a paper form for the majority of households in 2003, computer assisted interviewing was used for all survey interviews in the 2006, 2009 and 2012 surveys. This change in the methodology is not expected to impact on the comparability of the data between the surveys.
22 Changes between the 2000, 2003 and 2006 surveys are described in 'Comparability with previous ABS surveys' of the Explanatory Notes in Children's Participation in Cultural and Leisure Activities, April 2006 (cat. no. 4901.0). Changes between the 2006 and 2009 surveys are described in 'Comparability with previous ABS surveys' of the Explanatory Notes in Children's Participation in Cultural and Leisure Activities, April 2009 (cat. no. 4901.0). Changes between the 2009 and 2012 surveys are described below.
23 Data collected about information technology have changed between each iteration of this survey. In 2009 data were collected on children's personal safety and security in using mobile phones and the Internet as well as whether a child uses a mobile phone for contacting family or friends more. This information was not collected in 2012, and instead data on specific devices used to access the internet at home were collected.
24 For the 2012 survey data on organised art and craft were collected separately to recreational art and craft. In previous surveys, participation in art and craft activities were collected together, with no separation between the type of participation. As art and craft has been split into two different categories for 2012, no time series comparisons with previous versions of this survey should be made. For further information on recreational art and craft and organised art and craft see the Glossary.
25 For 2012, data collected for participation in cultural activities have changed. Data were not collected on the number of times a child participated in playing a musical instrument, singing, dancing, or drama in the last 12 months. Instead, information on participation in organised art and craft activities was included.
26 The scope of sports included in the 2012 survey has changed from previous years, with the focus now on organised sports. Physical activities that are not sports, such as jogging for exercise and gym workouts, are now excluded.
27 Numerous sports have had changes to their definitions compared with previous survey iterations, including: Australian Rules football; Gymnastics; Indoor soccer; Martial arts; Athletics, track and field; and Touch football. The combined total categories 'Other organised sport', 'At least one organised sport' and 'Organised sports and/or dancing' are therefore different in 2012 compared with previous years, and time series comparisons should not be made. For further information see the Glossary.
28 Country of birth data are classified according to the Standard Australian Classification of Countries (SACC), Second Edition, 2008 (cat. no. 1269.0).
PRODUCTS AND SERVICES
29 Summary results from this survey, compiled separately for each state and territory, will be available in a Datacube (spreadsheet form) from the ABS website www.abs.gov.au or on request to the ABS.
30 Special tabulations are available on request. Subject to confidentiality and sampling variability constraints, tabulations can be produced from the survey incorporating data items, populations and geographic areas selected to meet individual requirements. These can be provided in printed or electronic form.
31 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.
32 The ABS plans to conduct this survey again in April 2015.
