Contents >> Chapter 8. Special purpose ASGC codes >> Main structure

In the Main Structure special purpose codes relate to, in ascending hierarchical order: SLAs, SSDs, SDs and S/Ts.

Special purpose SLA codes

Four-digit SLA codes ending with 99 are reserved for coding undefined area data to SLA level. The first two digits of undefined SLA codes are normally in the range 00–89.

	Example:
	0199	Inner Sydney Undefined
	2799	Gosford-Wyong Undefined

These codes are used in the following cases:

Data required to be coded at SLA level but only able to be coded at SSD level, is coded to the undefined SLA within the defined SSD.

Example:
SD	SSD	SLA

05			Sydney
	70		Gosford-Wyong
		2799	Gosford-Wyong Undefined

Data required to be coded at SLA level but only able to be coded at SD level, is coded to the undefined SLA of the undefined SSD (see chapter 8) within the defined SD.

Example:
SD	SSD	SLA

05			Sydney
	88		Sydney Undefined
		0099	Sydney Undefined

A number of SLA codes within the range 0099–9999 are reserved for specific applications.

Code 0099 is reserved for the undefined SLA in each capital city SD.

Code 9899 is reserved for the undefined SLA within an undefined SD, within a defined S/T. For example, when data is required to be coded at SLA level but is only able to be coded at the S/T level, it is coded to SLA 9899.

Example:
S/T	SD	SSD	SLA

1	88	88	9899	Undefined New South Wales
8	88	88	9899	Undefined Australian Capital Territory

Code 9099 is reserved for the undefined SLA within an undefined SD, within an undefined S/T (see below). For example, when data is required to be coded at SLA level but is only able to be coded at the Australia level, it is coded to SLA 9099. This code is used to code Population Census data when usual residence information is not stated.

Code 9199 is used in ‘usual residence’ and similarly worded coding where the information is not applicable (e.g. children who had not been born five years ago).

Code 9299 is used in usual residence and similarly worded coding when the data relates to overseas.

Code 9399 is used as a dummy LGA to enable S/T totals to be produced for some LGA output from the Censuses of Population and Housing. In such circumstances, code 9399 equates to the aggregated unincorporated SLAs in each S/T.

Example:
S/T	LGA

7	9399	Aggregation of unincorporated SLAs, Northern Territory

Code 9499 is used for persons with no fixed place of abode, including children in care, persons in prison etc.

Special purpose SD and SSD codes

The two-digit code 88 is reserved for coding undefined area data to SSD and SD levels. A dummy SD, with an SD code of 88, exists for every S/T in the Main Structure, except Other Territories. Similarly there is a dummy SSD for every SD, except for Other Territories.

Example:
S/T	SD	SSD

1			New South Wales
	88		New South Wales Undefined
	05		Sydney
		88	Sydney Undefined

Special purpose S/T code

Data are coded to Undefined S/T when address details specify Australia only (i.e. without S/T details). The S/T code for Undefined S/T is 0. This code is also used to code Population Census data when usual residence is not stated.
