CLASSIFICATION AND CODING
THE STANDARD CLASSIFICATION AND CLASSIFICATION CRITERIA
The classification of persons by age uses the calculated time unit 'in complete years'.
'Age' is a flat classification containing one level.
The standard categories are single, complete, calendar years from 000 to 104 and a category for 105 and over.
THE CODE STRUCTURE
The code structure is 000 to 105. The examples below demonstrate the code structure applied to the Age classification:
|0 years |
|104 years |
|105 years and over |
Age has no provision for 'Not stated/Inadequately described' for ABS collections. In general, a 'best estimate' is provided for age, by derivation or imputation, based on other related variables in the questionnaire, or Any Responsible Adult (ARA) respondents. Data from sources (including administratively collected data), which have a 'Not stated' or 'unknown' code for Age may include a 'Not stated' category in output. Alternatively, the 'Not stated' response may be incorporated into totals, providing that the 'Total' is footnoted to show it includes these responses.
