Self-enumeration is the term used to describe the way Census data is collected. The Census forms are generally completed by householders (or individuals in non-private dwellings) rather than by interviewers, although interviewers are available in some areas.
Special purpose codes
Special purpose codes allow address data to be coded to a non-spatial value. This occurs where there is insufficient information to code to a physical geographic area. For example, responses with no fixed address or instances of incomplete location information.
Special purpose codes have been created for each hierarchical level within the Australian Statistical Geography Standard (ASGS) Main Structure. These codes are not spatial. They do not have a region associated with them in the various ASGS digital boundary sets.
In the Main Structure, special purpose codes relate to States/Territories, SA4s, SA3s, SA2s and SA1s. They are also included in other ASGS areas such as Greater Capital City Statistical Area (GCCSA) and in Non-ABS structures.
For more information, refer to the Australian Statistical Geography Standard (ASGS).
In a couple family, a step child is a child who is either the natural child of one partner but not of the other, or who was reported as being the step child of both parents. As a consequence of relationship breakdown or the death of a spouse, some one parent families may also have children reported as step children.
In practice, a person is considered a step child if the response 'step' is given for that person, regardless of the individual's dependency status.
