Multiple job-holders are people who work in more than one job at the same time. This multi-source release includes estimates of the number and prevalence of multiple job-holders, as well as socio-demographic, employment and industry characteristics of multiple job-holders.

Multiple job-holders may have varying reasons for holding more than one job. In most cases, a person's main job has a wages or hours constraint to it, which is why people look to working more jobs.

A ‘wages constraint’ is where someone has a job that does not pay enough for them during the week. They may then choose to work in a second job to supplement their wages.

An ‘hours constraint’ is where someone may work during the week, and have a second job on the weekends. This second job may have a higher wage but may not be available on a more frequent basis. An example of this is tutoring, working in elections, or refereeing sports games.

However, it should be noted that in some industries, a second job is used to expand job experience and portfolios. An example is the Health care and social assistance industry. Health care practitioners could work in their own private practice, as well as being a salaried hospital employee where they can gain experience or gain access to hospital facilities and equipment.

Sources of multiple job-holding data

The ABS has three main sources of data on multiple job-holders. These provide complementary information and insights into the number of multiple job-holders and their characteristics:

  • Labour Account – provides headline estimates of the level and rate of multiple job-holding, by industry
  • Labour Force Survey (LFS) – estimates of the number and socio-demographic, employment characteristics of multiple job-holders
  • Jobs in Australia (JIA) – estimates of the number and selected characteristics of multiple job-holders, based on personal income tax data available from the Linked Employer-Employee Dataset (LEED)

While the Labour Account-based headline estimates are derived from data collected in the LFS, the Labour Account includes adjustments to account for populations which are out of scope for the LFS, namely child workers, employed short-term non-residents and defence force personnel. The difference between the Labour Account and LFS-based estimates of multiple job-holders therefore reflects the (modelled) estimate of the number of multiple job-holders among those people who are out of scope of the LFS.

Some multiple job-holding data is also available from the Characteristics of Employment Survey. This survey is run as a supplementary survey to the Labour Force Survey annually in August.

How multiple job-holding is measured

Multiple job-holders are people who have more than one concurrent job in a specified period.

In the LFS (and Characteristics of Employment surveys), a multiple job-holder is someone who had more than one job at the same time during the LFS reference week.

In Jobs in Australia, a person is a multiple job-holder if they have more than one job concurrently over any 31 day period at any time during the financial year.

Strengths and limitations of each data source

Household surveys such as the LFS and Characteristics of Employment surveys have a range of socio-demographic and employment characteristics such as sex, age, family structure and educational attainment and occupation. Administrative data from Jobs in Australia releases are rich and detailed, but are almost 2 years behind.

The following table shows the strengths and limitations of each data source which was considered for this release:
