CHANGES TO GEOGRAPHY FOR THE SURVEY OF TOURIST ACCOMMODATION
What level of geography will be available?
Statistical Area Level 2
Under the ASGS, small area data will be produced at Statistical Area Level 2 (SA2) and will replace Statistical Local Area (SLA) data. To assist with this transition, there will be a dual release of small area data for the four quarters of 2012. Data will be released at both the SLA level (using ASGC 2011) and at the SA2 level (ASGS). As backcasting of historical STA data onto the ASGS is not possible, the dual release will allow users to continue with an ASGC time series for a 12 month period, whilst beginning a new ASGS time series at the same time.
Tourism Regions (TRs) will change to be constructed from allocations of whole SA2s rather than whole SLAs. Unlike SLAs which changed every year, SA2s will be reviewed only once every five years, therefore making these data more stable over time. Futhermore, SA2s are in general smaller than SLAs and, as they represent functional areas of regional towns, the SA2 based TRs are a better geographical representation of underlying social and economic interactions than the SLAs based TRs.
As TRs are defined each year by Tourism Research Australia (TRA) in consultation with State and Territory Tourism organisations, TR boundaries and names may still change each year as a result of this consultation.
A Statistical Geography Fact Sheet has been produced for Tourism Regions and how they fit into the ASGS. This contains further information on the ASGS which may be useful, and is available for download from the Statistical Geography Portal on the ABS website.
Local Government Area
Under the ASGC, Local Government Areas (LGAs) were made up of one or more SLAs. As the lowest level of geography available for the STA under the ASGC was SLA, it was possible to produce LGA level data by aggregating selected SLAs. Under the ASGS, a relationship does not exist between LGAs and SA2s. As SA2 is the lowest level of geography now available for the STA, it is no longer possible to produce LGA level data. As a result, the selected LGA data series which was produced for the STA will be discontinued. Similarly, data for the special area of 'Brisbane City Core' will also be discontinued.
When is the ASGS being released for the STA?
The ASGS will become the geographical framework for the STA from the March quarter 2012 and will affect all STA releases which contain small area data. STA data at the Australia and state/territory level will not be affected by the move to the ASGS. The first release of STA small area data based on the ASGS will be on 6 July 2012 in the following data releases:
What is available to assist in transitioning to the ASGS?
As a result of the move to the ASGS, Tourism Region boundaries for 2012 will change more than usual. For some TRs these changes are minimal, while for others the changes are more significant. To assist with understanding the changes to TR's which have been introduced through the introduction of the ASGS, two tourism specific products have been developed:
The first spreadsheet in the datacube contains a list of TRs where the location of the establishments is directly comparable for the old and the new Tourism Region (62 TRs). The second spreadsheet provides a list of TRs where the location of the establishments is not comparable and provides a detailed explanation of the changes which have occurred (18 TRs).
The ABS is also making an extensive range of correspondences available to assist with the implementation of the new statistical geography. Those of particular relevance for STA users will be '2011 SLA to SA2' and 'SA2 to LGA' correpondences. A complete list of correspondences which will be available and the dates they will be released are available from the Statistical Geography Portal on the ABS website, or by emailing email@example.com.
