Question(s) from the Census form
This variable is not collected from a direct question on the Census form.
How this variable is created
Most occupied private dwellings return a completed form, so the number of persons is known. This variable identifies those private dwellings where the number of people are imputed.
History and changes
This variable was first used in the 2006 Census. The categories for this item were changed in 2016 due to the changes in dwelling enumeration.
Prior to the 2016 Census, Census Field Officers would collect information on number of males and females in residence during their visits to the dwelling. This information would be recorded in their collector record books and could be used instead of imputation if there was no response from the dwelling. This information was not collected during the 2016 Census and if a dwelling did not respond the only option was to impute the number of males and females based on similar dwellings. This flag is set during Census processing.
No changes have been made for 2021.
Data use considerations
For imputed persons, the following person variables are also imputed:
All other person variables are set to ‘Not stated’ or ‘Not applicable’ for imputed persons.
Non-response rate only applies to data items that directly reflect responses to individual Census form questions. This imputation flag does not have a non-response rate as it is used to indicate whether the number of males and females were imputed during Census processing for applicable households. For more information on imputation, see Census Methodology.
