Australian Standard Geographical Classification - Remoteness Area (ASGC-RA)
What is ASGC-RA?
The purpose of the structure is to classify data from census Collection Districts (CDs) into broad geographical categories, called Remoteness Areas (RAs). The RA categories are defined in terms of ‘remoteness’ - the physical distance of a location from the nearest Urban Centre (access to goods and services) based on population size. A primary advantage of the new classification system is that the remoteness structure is updated each census, which commenced with the census year 2001. It was updated recently on 8 November 2007 after the 2006 census.
What are the RA Categories?
RA1 - Major Cities of Australia
RA2 - Inner Regional Australia
RA3 - Outer Regional Australia
RA4 - Remote Australia
RA5 - Very Remote Australia
How is RA Calculated?
Remoteness is calculated using the road distance to the nearest Urban Centre in each of five classes based on population size. The key element in producing the RA structure is the preparation of the Accessibility/Remoteness Index of Australia (ARIA+) grid – a statistical geography structure created by the National Key Centre for Social Applications of Geographic Information System (GISCA), Adelaide University, South Australia.
ARIA+ scores are first calculated for each Urban Centre, in 1km square grids. These are then added together, covering the whole geography of Australia. Each grid square carries a score of remoteness from an index of scores ranging from zero through to 15.
RAs are created by averaging the ARIA+ scores within CDs, then aggregating the CDs up into the 5 RA categories based on the averaged ARIA+ score.
