This publications presents a suite of geographical correspondences primarily to assist users make comparisons and maintain time series between the previous Australian Standard Geographical Classification (ASGC) and the new Australian Statistical Geography Standard (ASGS). Correspondences are a mathematical method of reassigning data from one geographic region to another geographic region.
These correspondences have been created using a new methodology. It uses a population weighted grid, representing either 2006 Census Collection Districts (CD) or 2011 Mesh Block (MB) population data, which creates far more accurate correspondences than have been previously available.
Correspondences need to be used with care. Issues surrounding the use of correspondences are discussed in the ABS publication: Information Paper: Converting Data to the Australian Statistical Geography Standard, 2011 (cat. no. 1216.0.55.004).
Additional correspondences will be added to this product as they become available. These can be found under the 'Data Cubes' section of this publication under the 'Downloads' tab.
A list of available and upcoming correspondences, coding indexes and hierarchy tables is available in the ‘Correspondences’ chapter on the ABS Statistical Geography website: https://www.abs.gov.au/geography
