To identify households with members aged 15 years and over temporarily absent on Census Night the following variables are used:

  • Count of persons temporarily absent from dwelling (CPAD)
  • Count of persons/dependent children temporarily absent from family variables (CPAF)

History and changes

This variable was first introduced in the 1991 Census.

No changes have been made for 2021.

Data use considerations

This variable allows household income to be derived from individual incomes based on certain conditions as listed in the categories.

Household income derivation indicator can also be used:

  • to remove these households from the population of a table, or to estimate the impact on total household income caused by negative income or people away from the dwelling on Census Night
  • in conjunction with Total personal income (weekly) (INCP) to create a new household income variable.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.
