Age has been collected in all Australian Censuses. Age data, combined with sex data, are essential for the production of accurate population estimates based on the Census count.
The 2011 Census form gives respondents the option of writing in their age and/or their date of birth. Age is calculated from date of birth when provided, otherwise stated age is used. Only age in years data are output. If neither age nor date of birth is provided, age is imputed using other information on the form and using an age distribution of the population. The variable Imputation Flag for Age (IFAGEP) is used to indicate if a person's age has been imputed for the Census.
For 2011, AGEP classifies each person's age into single year categories, from 0 to 115 years. For infants aged less than one year, 0 years of age is recorded.
Age is used during processing as a cross check with other variables; for example, the age of the respondent determines whether particular questions asked in the Census are applicable.
If age is under 15 years, then the following person variables are not applicable:
The following age constraints apply:
