          More information

          Information from this question provides an indication of living standards in different areas.

          Count total income from all sources, not just a regular wage or salary. Total income is the person's personal income before any tax, superannuation contributions, amounts salary sacrificed or other automatic payments are deducted.

          If the person is currently affected by COVID lockdown restrictions, report the total income they usually received before the lockdown began.

          Government pensions, benefits and allowances

          Include:
          • Age Pension
          • Family Tax Benefit

          • Youth and student allowances
          • Carer Allowance
          • Any other government pension, benefit or allowance

          Note: remember to include the total value of any pensions, benefits and other government allowances that the person is currently receiving.

          Business owners and self-employed people
          Business owners and self-employed people should include the total profit or loss from the operations of their business, or their share of the business in a partnership.
          The profit or loss of a business is calculated as its gross receipts less its operation expenses (such as rent, materials and fuel costs).
          If the person has other sources of income, such as wages or government allowances, these should be added to their business income to calculate their total income from all sources.

          Other income
          For interest and dividends, calculate the amount the person expects to receive in a full year and add this to their total yearly income from other sources; divide by 26 to work out a fortnightly amount; or, divide by 52 to work out a weekly amount.
          For other regular income, such as superannuation or child support, include the amount the person currently receives for one week or fortnight, or calculate the amount they expect to receive in a full year and add this to their total yearly income from other sources.
          Include Private Pensions and Workers Compensation under Other income.

          Negative income
          Negative income occurs when the operating expenses are higher than the gross receipts (or revenue) of a self-employed person, business or a rental property. A person has negative income if these losses are greater than any income, benefits or allowances received from other sources.

                              How this variable is created

                              Data for this variable is collected from the Relationship in household and Income questions on the Census form and the questions asked of people who were away from the household on Census night.

                              This variable is derived from the Family composition (FMCF) and Total personal income (INCP) variables. It also uses the Count of persons/dependent children temporarily absent from family variables (CPAF and CDCAF) to isolate families with members aged 15 and over temporarily absent on Census night.

                              History and changes

                              This variable was first introduced in 1991. No changes have been made for 2021

                              Data use considerations

                              This variable can be used in conjunction with Total personal income (weekly) (INCP) to create a new family income variable.

                              Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census night. In this case they should be included in the section of the form for people who were away on Census night. This can occur in both family and group households. Due to form limitations a maximum of three people can be reported and coded as temporarily absent from the dwelling. If more than three people are absent from the household the additional people are unable to be included on the form.

                              Family income derivation indicator 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.
