The Census form seeks information about people who usually reside in a dwelling but who are temporarily absent on Census Night. Coders use the following temporary absentees in determining household and family classifications:
- co-tenants or unrelated flatmates (used to classify group households).
The only information gathered on temporarily absent persons are name, sex, age, Aboriginal and/or Torres Strait Islander origin, person's relationship in household and whether the person is a full-time student. This information is used to assist in family coding. All other information for persons temporarily absent and in Australia on Census Night, should have been obtained at their place of enumeration. However, this information is not able to be related back to this dwelling.
