Demographics

State/territory

The state or territory of the school the respondent attended at the time of the first interview.

Sex

The gender the respondent reported at the time of the first interview.

Indigenous status

Indigenous respondents are identified by recording responses to the following question asked at the time of the first interview:

• ‘Are you an Aboriginal person or Torres Strait Islander person?’ (for the Y95 and Y98 cohorts)
• ‘Are you of Aboriginal or Torres Strait Islander origin?’ (for the Y03, Y06, Y09 and Y15 cohorts)
  Indigenous status is split into two categories: ‘Indigenous’ and ‘Non-Indigenous’.

For the Y98 cohort

Missing or invalid responses are coded to the ‘Non-Indigenous’ category.

Geographic region

The geographic region of the school the respondent attended at the time of the first interview.

Geographic region is categorised as: ‘Metropolitan’ and ‘Non-metropolitan’. Missing or invalid responses are coded to the ‘Metropolitan’ category.

• Metropolitan areas are defined as those with a population size of 100 000 or more.
• Non-metropolitan areas are defined as those with a population size less than 100 000.

Country of birth

The country of birth reported at the time of the first interview. Country of birth is categorised as: ‘Australia’ and ‘Other’. Respondents born outside of Australia, missing and invalid responses are coded to the ‘Other’ category.

School sector

Socio-economic status

For the Y95 and Y98 cohorts
The ANU3 measure, an indicator of socioeconomic status based on occupational prestige, has been used in the calculation of socioeconomic status. ANU3 uses the Australian Standard Classification of Occupations (ASCO) schema to determine the socioeconomic status of the respondent based on their parents’ occupation.  Parental occupation is based on father’s occupation when available and mother’s occupation when information on father’s occupation is absent. The scale ranges from 0 to 100. More information about the scale can be accessed at: https://journals.sagepub.com/doi/10.1177/144078330003600105

For the Y03, Y06, Y09 and Y15 cohorts
The socioeconomic status quintiles are calculated using the PISA Economic, Social and Cultural Status (ESCS) index.

Reading achievement

For the Y03, Y06, Y09 and Y15 cohorts
The reading achievement quartile derived using reading plausible values from testing conducted at the time of the first interview.

Science achievement

For the Y03, Y06, Y09 and Y15 cohorts

For respondents with more than one job, the average weekly pay of the main job is reported. It does not consider pay from additional jobs, or pay from job/s the respondent later reclassified as their main job.

Outliers are retained with the exception of one extreme pay value for the Y15 cohort in wave 6 and two extreme values for the Y15 cohort in wave 8.

For the Y95, Y98, Y03, Y06 and Y09 cohorts

This indicator includes those who are working for wages or salary. Respondents who are self-employed do not report a rate of pay so are excluded from the figures reported.

In 2020 (due to the coronavirus pandemic):

• respondents who reported receiving the JobKeeper payment were assigned the higher value of either the JobKeeper weekly threshold or their usual weekly pay
• in place of “usual hours”, “usual (pre-COVID) hours” and “current hours” worked were asked of respondents, and “current hours” was used to derive average weekly pay.

Since 2020, respondents could report they were working zero hours; if these respondents reported their hourly pay, they were not assigned an average weekly pay value (with the exception of those who reported receiving the JobKeeper payment in 2020).

Average hourly pay

The average hourly pay for those employed at the time of interview. Respondents who: are working in ways other than for wages/salary, are waiting to start work, did not provide a rate of pay, or provided their weekly/fortnightly/annual pay rate but did not provide their weekly hours worked are excluded from the figures reported.

For respondents with more than one job, the average hourly pay of the main job is reported. It does not consider pay from additional jobs, or pay from job/s the respondent later reclassified as their main job.

Outliers are retained with the exception of one extreme pay value for the Y15 cohort in wave 6 and two extreme values for the Y15 cohort in wave 8.

For the Y95, Y98, Y03, Y06 and Y09 cohorts

This indicator includes those who are working for wages/salary or self-employed in their own business.

For those who were self-employed, weekly business earnings are used to calculate average hourly pay.

For the Y95 and Y98 cohorts
For those who are working for wages or salary, take-home pay is recorded at waves 1 and 2, while gross weekly pay is recorded for all remaining waves.

For the Y03, Y06, Y09 and Y15 cohorts

Average weekly hours worked

The average weekly working hours for those employed at the time of interview. Respondents who: are waiting to start work or did not provide the number of hours they work each week are excluded from the figures reported.

For respondents with more than one job, the hours worked of the main job is reported. It does not consider hours worked from additional jobs, or hours worked from job/s the respondent later reclassified as their main job.

Employment satisfaction indicators include: The kind of work you do, Opportunities to use your skills and experience, Your immediate boss or supervisor, Other people you work with, The pay you get, Opportunities for training, The tasks you are assigned, Recognition you get for tasks well done, and Your opportunities for promotion.

The Y15 cohort has an additional satisfaction indicator: The flexibility you have to balance work and non-work commitments.

These cohorts use a 5-point scale with the following classifications:

• 1 = 'Very satisfied'
• 2 = 'Fairly satisfied'
• 3 = 'Fairly dissatisfied'
• 4 = 'Very dissatisfied'
• 5 = 'Neither satisfied nor dissatisfied’.

Other terms and definitions

Not in the labour force (NILF)

Respondents who are not working and are not actively looking for work are classified as being not in the labour force.

The Australian Standard Classification of Occupations (ASCO)

The ASCO is a skill-based classification system used to classify all jobs in the Australian labour market. It defines jobs and occupations according to level of skill and specialisation. It uses similarities between these attributes to organise them into three hierarchical levels: major group, minor group and unit group and occupation.

ASCO First Edition was released in 1986. The classification structure of the Second Edition was released in July 1996.

Australian New Zealand Standard Classification of Occupations (ANZSCO)

The ANZSCO is a skill-based classification system used to classify all jobs in the Australian and New Zealand labour markets. It defines jobs and occupations according to level of skill and specialisation. It uses similarities between these attributes to organise them into five hierarchical levels: major group, sub-major group, minor group, unit group and occupation.

ANZSCO replaced the ASCO and the New Zealand Standard Classification of Occupations (NZSCO) in 2006.
