The Remoteness graphs and associated data are based on the ABS Remoteness Structure.
The Australian Bureau of Statistics' (ABS) Australian Statistical Geography Standard (ASGS): Volume 5 - Remoteness Structure1 is a framework for statistical geography, which defines locations in terms of remoteness2. Geographic remoteness is essentially a measure of a physical location's level of access to goods and services3. Large population centres tend to have a greater range of goods and services available than small centres.
The measures of remoteness used by the ABS are based on population estimates obtained from the Census of Population and Housing, conducted every five 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.3
Box 1: Classification of Remoteness Areas in Australia
The ABS Australian Statistical Geography Standard (ASGS) Remoteness Structure allocates areas to one of six Remoteness Areas depending on their distance from urban centres, where the population size of the urban centre is considered to govern the range and types of services available. Remoteness Areas used in PHIDU reports cover the following five categories: Major Cities of Australia, Inner Regional Australia, Outer Regional Australia, Remote Australia and Very Remote Australia. The sixth Remoteness Area covers populations in areas recorded as off-shore, migratory and shipping and is not of relevance to the data in these reports.
The category Major Cities includes Australia’s capital cities, with the exceptions of Hobart and Darwin, which are classified as Inner Regional and Outer Regional, respectively.
From April 2018 data are being coded to Remoteness Areas released by the ABS in March 2018 and are presented under the `latest’ period heading.
In the time series set, data coded to classifications for 2006 and earlier have been re-compiled to match the 2011 Remoteness Area, and later data have been re-coded to those 2011 areas.
Readers should note that the presentation of data by Remoteness Area is dependent on the recording of addresses in the various administrative data collections from which data in this report are drawn.
