CHAPTER 22. MULTI-PURPOSE HOUSEHOLD SURVEY


INTRODUCTION

22.0.1 The Multi-Purpose Household Survey (MPHS) was introduced in 2004–05. This survey vehicle is designed to provide statistics annually for a number of small, self contained topics, including a number of labour related topics:

    • Barriers and Incentives to Labour Force Participation (conducted every two years, commencing with 2004–05);
    • Retirement and Retirement Intentions (conducted every two years, commencing with 2004–05); and
    • Work Related Injuries (conducted every four years, commencing with 2005–06).

22.0.2 This chapter describes the broad survey methodology of the MPHS. For information on the three labour related MPHS topics that have been conducted to date, see
Chapter 22.1 (Barriers and Incentives to Labour Force Participation), Chapter 22.2 (Retirement and Retirement Intentions) and Chapter 21.15 (Work-Related Injuries).


OBJECTIVES OF THE MULTI PURPOSE HOUSEHOLD SURVEY

22.0.3 The MPHS topics are an important part of the ABS's household surveys program, which aims to:
    • provide a range of statistics needed to monitor the social and economic wellbeing of Australians with particular reference to important sub-groups of the population; and
    • support the development, implementation and evaluation of policies and programs of key Commonwealth and State government agencies.

22.0.4 The information requirements of MPHS topics are determined on the basis of submissions from users on their needs for, and uses of, household survey data. They also reflect ABS deliberations on what is required of a national statistics program in the various subject fields, based on user contact and consultation.

22.0.5 The MPHS is a flexible multi-topic survey vehicle which is used to collect and output data in a timely fashion. The MPHS includes a number of topics that require personal interview (rather than using the any responsible adult (ARA) method) and are therefore unsuited to the monthly supplementary program. The MPHS has a shorter development and output time than the special social surveys to achieve flexibility in responding to user demands as they arise and to allow the ABS to respond to emerging demand and contemporary priorities in a timely way (publications are usually available within six months of the completion of data collection).

22.0.6 In addition to the labour-related topics outlined in paragraph 22.0.1, the MPHS program also includes other social topics not related to labour statistics, such as household use of information technology, patient experience, family transitions and people's attitudes to the environment.


SURVEY OUTPUT

22.0.7 Estimates from each MPHS topic are released in separate publications. Expanded Confidentialised Unit Record Files (CURFs) are made available from each MPHS via the Remote Access Data Laboratory (RADL). Information on CURFs and the RADL can be found on the ABS web site, under
Services – Microdata - CURFs and TableBuilder.


SCOPE

22.0.8 As with the Labour Force Survey (LFS) the scope of the MPHS is restricted to people aged 15 years and over and excludes:
    • members of the permanent defence forces;
    • certain diplomatic personnel of overseas governments, customarily excluded from census and estimated population counts;
    • overseas residents in Australia; and
    • members of non-Australian defence forces (and their dependants) stationed in Australia.

22.0.9 In addition, the following people are excluded from most MPHS topics (see paragraphs
18.2 to 18.4 of Chapter 18 for further information):
    • people living in very remote parts of Australia;
    • 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), and inmates of prisons; and
    • for 2004–05 only, people aged 15–17 years.

22.0.10 Depending on the topic, there may be further exclusions from scope. For example, some MPHS topics collect information only from a certain population or interest group (e.g. information on retirement is collected from people aged 45 years or over).


COLLECTION METHODOLOGY

22.0.11 The MPHS is conducted in conjunction with the monthly Labour Force Survey (LFS). Approximately one third
of the dwellings in the LFS out-going rotation group (one eighth of the sample is rotated out each month) are selected for enumeration in the MPHS. For 2008–09, half of the dwellings in the LFS out-going rotation group were selected for enumeration to compensate for the decreased sample in the LFS (see Chapter 20). From each dwelling selected for the MPHS, one person is randomly selected for interview.

22.0.12 Data are collected using Computer Assisted Interviewing (CAI), whereby responses are recorded directly onto an electronic questionnaire in a notebook during a telephone or face-to-face interview.

22.0.13 Data for MPHS topics are collected each month over a financial year. This reduces the impact of any seasonal effects on the data. For the first MPHS, conducted in respect of 2004–05, interviewing commenced in August 2004 rather than July. For the 2006–07 MPHS, no interviews were conducted in August or September 2006.


SAMPLE DESIGN

22.0.14 The MPHS uses the same sample design as the LFS. The sample used in the MPHS is a subset of the LFS sample. Each month a sample of approximately 1,250 dwellings are selected.

22.0.15 The size of the annual sample selected is approximately 15,000, but the response rates for the MPHS are slightly lower than for the LFS (averaging around 88%). The number of fully responding households is therefore usually around 13,000. The size of the MPHS sample can be increased with user funding.


ESTIMATION METHODS

22.0.16 The estimation technique used for household surveys is the generalised regression estimator.

22.0.17 The survey is benchmarked to the estimated civilian population aged 15 years and over living in private dwellings in each state and territory in non-sparsely settled areas. The process of weighting ensures that the survey estimates conform to person benchmarks by state, part of state, sex, age and household composition.


RELIABILITY OF THE ESTIMATES

22.0.18 Estimates from the MPHS are subject to both sampling and non-sampling error (see
Chapter 17 for more detail). The relative standard errors (RSEs) for each of the survey estimates are published in shadow tables. For further information on calculating RSEs from the MPHS, see the technical notes of each publication.

22.0.19 A 'group jack-knife' variance estimator is used to calculate estimates of variance (see
Chapter 17 for more detail).
