CHAPTER 21.9. MULTIPLE JOB HOLDERS
Labour Statistics: Concepts, Sources and Methods was originally released in 2001 in both electronic and paper versions (cat. no. 6102.0). The paper publication will not be rereleased. However, the web version (cat. no. 6102.0.55.001) is being updated on an ongoing basis. This chapter was updated on 20 September, 2007.
INTRODUCTION
21.9.1 The Multiple Job Holders Survey collects information on the number and characteristics of employed persons who have more than one job. Information on multiple job holders has been collected on an irregular basis since 1965.
21.9.2 This section describes only those aspects of the methodology that are unique to this survey, and hence should be used in conjunction with the overview part of this chapter, which outlines the survey methodology used in supplementary surveys.
SURVEY OUTPUT
21.9.3 The Multiple Jobholders Survey was first conducted in 1965, then every two years from August 1973 until August 1987. It was then conducted in July 1991, August 1994, August 1997 and July 1998. Data from the survey were last published for August 1997, however estimates from the July 1998 survey are available on request. Estimates from previous surveys have been published in Multiple Jobholding, Australia (cat. no. 6216.0).
21.9.4 Data from the survey relate to persons aged 15 and over. The main population of interest is employed persons (excluding contributing family workers and persons working solely for payment in kind) with more than one job. Estimates are produced on an original basis only (i.e. not seasonally adjusted) and include:
Socio-demographic information
Sex, age, marital status, relationship in household, family, geographic region, birthplace and year of arrival in Australia.
Multiple job holders
Labour force characteristics of main and second job including status in employment, full-time/part-time status, hours worked, occupation, industry, weekly earnings, and whether worked in second job in the survey reference week.
21.9.5 Data collected in the survey are compiled according to concepts and definitions outlined in Chapter 4 (employment characteristics) and Chapter 16 (socio-demographic information and industry other classifications used in labour statistics).
SCOPE
21.9.6 The scope of this survey is restricted to employed persons aged 15 years and over. The standard scope restrictions for supplementary surveys outlined in the overview part of Chapter 21 also apply to this survey.
DATA COMPARABILITY OVER TIME
21.9.7 In order to provide a high degree of consistency and comparability over time, changes to survey methods, survey concepts, data item definitions, frequency of collection, and analysis methods are made as infrequently as possible. Over the time the survey has been conducted there have been some changes to the scope and sample size. These changes mean that the standard errors for the survey differ over time. The effect on estimates of the change in scope is considered to have been small. Changes affecting the Labour Force Survey may also affect this survey. Such changes are outlined in Chapter 20 and are not repeated here.
