SURVEY METHODOLOGY
The 2013-14 Work-Related Injuries TableBuilder dataset is compiled from the 2013-14 Multipurpose Household Survey (MPHS) which is conducted as a supplement the monthly Labour Force Survey (LFS). The scope of the LFS is restricted to people aged 15 years and over and excludes the following:
- members of the permanent defence forces;
- certain diplomatic personnel of overseas governments, customarily excluded from the census and estimated resident populations;
- overseas residents in Australia; and
- members of non-Australian defence forces (and their dependants).
The 2013-14 MPHS also excluded:
- people living in remote Aboriginal and Torres Strait Islander communities in Australia; and
- people living in non-private dwellings such as hotels, university residences, students at boarding schools, patients in hospitals, residents of homes (e.g. retirement homes, homes for people with disabilities, women's shelters), and inmates of prisons.
The coverage of the 2013-14 MPHS was the same as the scope, however for operational reasons it also excluded persons living in non-very remote Aboriginal and Torres Strait Islander communities.
Each month one eighth of the dwellings selected in the LFS sample are rotated out of the survey. These dwellings are called 'the outgoing rotation group'. In these dwellings, after the LFS had been fully completed for each person in scope and coverage, a person aged 15 years or over was randomly selected and asked the MPHS questions in a personal interview.
Proxy interviews are conducted for persons aged 15-17 years if an adult member of the household does not grant permission to allow the 15-17 year old respondent to personally respond to the interview. If permission is not granted, the adult member of the household responds to the interview on behalf of the 15-17 year old. For some questions which call for personal opinions, such as self-assessed health status, responses from proxy interviews are not collected.
The number of completed interviews obtained for the 2013-14 work-related injuries topic was 27,300.
More information about the concepts and methods particular to the 2013-14 MPHS work-related injuries topic is available in the publication Work-Related Injuries, Australia (cat. no. 6324.0). The concepts and methods described in Labour Force, Australia (cat. no. 6202.0) are also relevant to the MPHS.
DIFFERENCES BETWEEN THE TABLEBUILDER DATASET AND PREVIOUSLY PUBLISHED STATISTICS
ABS microdata are released under the Census and Statistics Act 1905 which has provision for the release of data in the form of unit records where the information is not likely to enable identification of a particular person or organisation. Steps taken to protect the confidentiality of respondents also maintain the integrity of the data and optimise the content of the TableBuilder file. One of the steps includes perturbation, which alters values to reduce the risk of identification of respondents.
Due to perturbation, estimates in the Work-Related Injuries TableBuilder dataset will not directly match the estimates published in the summary publication. The statistical validity of aggregate data is not affected.
