SUPPORT FOR THE AUSTRALIAN STANDARD GEOGRAPHICAL CLASSIFICATION (ASGC) AND TIME SERIES
The change in classification means there will be an unavoidable break in time series. For the 2011 Census the ABS will assist users to move to the ASGS while still meeting needs for time series data. The Statistical Local Area (SLA) is not a defined region in the new ASGS but will be available for the 2011 Census. The SLA is a transitional unit to allow for comparison to the 2006 Census and will not be available for 2016. Census data for Local Government Areas (LGAs) will continue to be made available for the 2016 Census and beyond.
It should be noted that time series data from the 2011 Census will be available for Australia, States and Territories, 2011 SLAs and 2011 LGAs. The lowest level of time series data available from the census as standard output has been the SLA and this remains unchanged for 2011.
To also assist users transition to the new geography, the ABS will continue to publish the ASGC up until 2011 and the ABS invites you to comment on levels of the ASGC geography you would like to continue to see made available as standard output for the 2011 Census. It should be noted however, that Collection Districts have not been developed for the 2011 ASGC and will not be available as output from the 2011 Census. This includes time series, as data quality at the CD was considered to be of insufficient quality for comparison over time.
The 2011 Census marks the beginning of a new improved time series. A series that is based on a more stable and consistent geographic standard. More information on the new time series will be available in the lead up to the 2016 Census.
