This includes families where one or more family members did not have income information available in administrative data or was absent from the dwelling on Census Night.  

This variable wasn’t derived from data collected on the Census form but has been created by linking administrative data from the Person Level Integrated Data Asset (PLIDA) to the Census.

How this variable is created

This variable wasn’t derived from data collected on the Census form but has been created by linking administrative data from the Person Level Integrated Data Asset (PLIDA) data asset to the Census. The PLIDA data asset contains administrative income data from the Australian Taxation Office and the Department of Social Services, this is the source data for this variable.   

This variable is calculated by summing the personal incomes recorded in administrative data for all family members aged 15 years and over.  

The income ranges for this variable include families where one or more members aged 15 years and over was not able to be linked to PLIDA, and therefore did not have income information available in administrative data; or was absent from the dwelling on Census Night. In the variable Total family income (administrative data) (weekly) (FINAF), these families were excluded from the family income calculation and coded to the category 'Partial incomes available'. 

Families where no family member aged 15 and over was able to be linked to PLIDA, and therefore did not have administrative income information available are set to 'Admin not available'. 

History and changes

This is a new variable for 2021.

Data use considerations

This variable provides an alternative, more detailed view on income to the Census income data collected via the Census form. It is based on income information recorded in linked administrative data, and not data collected from a Census question.  

Comparison to Census income data 

Although this variable provides an alternative, more detailed view on income to the income data collected via the Census form, there are differences to consider. 

Method to calculate family income 

The personal incomes used to create this variable were recorded to the nearest dollar. The Census question, on the other hand, collects personal income in ranges, then a median-based approximation is used to calculate family income. 

Unlike data collected via the Census form, this variable does not rely on people correctly recalling the income that they, and other household members, usually earn.  

Comparisons to other family data 

This variable should be used with caution when comparing to other family data from within the ABS and for external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.
