Definition:Help on this term

Australian Statistical Geography Standard-Remoteness Area (ASGS-RA) is a geographical classification which defines locations in terms of remoteness, i.e. the physical road distance of a location from the nearest Service Centre (a populated locality where the population is greater than 1,000 persons), within population size categories.

Context:Help on this term

Geographic remoteness is essentially a measure of a physical location's level of access to goods and services. Large population centres tend to have a greater range of goods and services available than small centres. Typically, a population centre is not likely to provide a full range of goods and services until its population reaches around 250,000 people.

The measures of remoteness used by the Australian Bureau of Statistics (ABS) are based on population estimates obtained from the Census of Population and Housing, conducted every 5 years. Remoteness measures are calculated using Accessibility/Remoteness Index of Australia (ARIA+) scores, which are based on the distance of geographic locations from the nearest population centre in various size ranges. The lower the ARIA+ score for a location, the better its level of access to goods and services.

Information in relation to how remoteness is defined and calculated is available from the Geography portal on the ABS website.

Information in relation to how ARIA+ scores are calculated for physical locations is available from the Australian Population and Migration Research Centre (APMRC) website.

Collection and usage attributes

Guide for use:Help on this term

This value domain is intended exclusively for use in the analysis of data relating to the Pharmaceutical Benefits Scheme (PBS).

In the context of PBS data, the allocation of remoteness categories is based on the postcodes of patients, prescribers or pharmacies, as appropriate. Postcode areas are converted to Statistical Area Level 1s (SA1s) which are then used to allocate remoteness categories.

CODE 1   Major cities of Australia

'Major cities of Australia' includes postcode areas that correspond with SA1s with an average Accessibility/Remoteness Index of Australia (ARIA+) index value of 0 to 0.2.

This code approximates Code 1 in the more widely used value domain Remoteness classification (ASGS-RA) N.

CODE 2   Inner and Outer regional Australia

'Inner regional Australia' includes postcode areas that correspond with SA1s with an average ARIA+ index value greater than 0.2 and less than or equal to 2.4.

'Outer regional Australia' includes postcode areas that correspond with SA1s with an average ARIA+ index value greater than 2.4 and less than or equal to 5.92.

This code approximates Codes 2 and 3 in the more widely used value domain Remoteness classification (ASGS-RA) N.

CODE 3   Remote and Very remote Australia

'Remote Australia' includes postcode areas that correspond with SA1s with an average ARIA+ index value greater than 5.92 and less than or equal to 10.53.

'Very remote Australia' includes postcode areas that correspond with SA1s with an average ARIA+ index value greater than 10.53.

This code approximates Codes 4 and 5 in the more widely used value domain Remoteness classification (ASGS-RA) N.

Collection methods:Help on this term

In this value domain, physical distance is defined in terms of ARIA+ index values, rather than a simple linear distance between points.

Comments:Help on this term

Prior to 2011, ARIA+ scores were calculated for individual Census Collection Districts (CCDs). Following the phasing out of the Australian Standard Geographical Classification (ASGC) and the introduction of the Australian Statistical Geography Standard (ASGS) by the ABS in 2011, ARIA+ scores are calculated for individual Statistical Area Level 1s (SA1s).
