Total household income (administrative data) (weekly) (HINAD)

This variable is the sum of Total personal income (administrative data) (weekly) (INCAP) of each resident aged 15 years or older who was present in the household on Census Night. This excludes households where one or more resident did not have income information available in administrative data or was absent from the dwelling on Census Night. These households are coded to the 'Partial incomes available' and total household incomes are not calculated. 

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. 

Occupied private dwellings

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. 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 of all household members aged 15 years and over. 

Households where all or at least one member aged 15 and over was not able to be linked to PLIDA, and therefore did not have income information available in administrative data are set to: 

• ‘Admin not available’ and 
• ‘Partial incomes available’ respectively. 

Households where at least one member aged 15 and over was away from the dwelling on Census Night are also set to ‘Partial incomes available’. 

In most cases, the income of visitors to a household are excluded from this variable. The exception to this is households that comprise only visitors. 

This is a new variable for 2021.

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 income data collected via the Census form, there are differences to consider.

Method to calculate household 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 household 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.  

Comparison to other ABS Surveys 

Although other ABS surveys, such as the Survey of Income and Housing and Personal Income in Australia, collect similar data relating to household income, they are not directly comparable. This is due to differences in scope, collection methodology, collection period, and conceptual differences. It is likely that data from each of these collections will deliver different outcomes making it important for data users to understand the key conceptual differences between each collection to use it most appropriately.
