2011 Census Dictionary >> Glossary >> Special Purpose Codes


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.

Special Purpose Codes Used in Census

Capital City, Not Further Defined
Used to code place of usual residence one and five years ago. Used where a respondent has given incomplete address information on the Census form. But has given enough information to allow coding to a capital city.

Migratory
