THE STRUCTURE

Incorporated areas only

The LGA Structure covers only incorporated areas of Australia. Incorporated areas are legally designated parts of states and territories over which incorporated local governing bodies have responsibility. The major areas of Australia not administered by incorporated bodies are the northern parts of South Australia and all of the Australian Capital Territory and the Other Territories.

In Population Census years the LGA Structure has four levels of hierarchy, in ascending order these are: CDs-SLAs-LGAs-S/Ts (Incorporated Areas). In non-census years CDs are not defined and consequently the LGA Structure has only three levels: SLAs-LGAs-S/Ts (Incorporated Areas). The spatial units in each level relate to each other in a straightforward manner: LGAs comprise one or more whole SLAs and SLAs comprise one or more whole CDs.

Processing LGAs for the ASGC

LGAs are proclaimed by state and territory government authorities and changes are gazetted throughout the year. The ABS has broadened the categories of legislation used to define local government areas for statistical purposes to include the Indigenous Council areas in the States.

LGAs are used as the base on which SLAs are defined. Because this definition process takes time, LGAs gazetted during the year leading up to an ASGC edition cannot always be included in that edition. For instance, complex LGA changes which result in complicated redesign of SLAs, or changes gazetted too close to the effective date of 1 July of an ASGC edition, may have to be included in a later edition.

Table

The current LGA Structure, down to SLA level, is shown in Chapter 15, The Classification Structures.

For example:

Local Government Areas and Statistical Local Areas - Alphabetic

S/T	LGA Name	LGA	SLA Name	SD	SSD	SLA


1	Albury (C)	10050	Albury (C)	155	15505	155050050
1	Armidale Dumaresq (A)	10110
1			Armidale Dumaresq (A) - City	130	13015	130150111
1			Armidale Dumaresq (A) Bal	130	13015	130150112

Note that there is no SD or SSD code for the LGA because LGAs are not part of the Main Structure. This table also shows SLAs which cover unincorporated areas and are therefore not part of the LGA Structure.

For example:

S/T	LGA Name	LGA	SLA Name	SD	SSD	SLA

1	Unincorporated NSW	19399
1			Unincorp. Far West	160	16010	160108809
1			Lord Howe Island	125	12510	125108859
