SEPTEMBER KEY POINTS
CHANGES IN THIS ISSUE
Each September, the reference year for chain volume estimates is updated. A new price reference year, 2009-10, has been introduced into the chain volume estimates. In addition, the chain volume estimates have been re-referenced to 2009-10. Additivity is preserved in the quarters of the reference year and subsequent quarters. Re-referencing affects the levels of, but not the movements in, chain volume estimates.
This September, the chain volume estimates have also been revised as result of updates to the price deflator weights. These weights are necessary to combine detailed price indexes into a single deflator to estimate published chain volumes. Updates to the weights are associated with the introduction of updated sources of benchmark data into the compilation of the Australian System of National Accounts. In particular, new retail data has been incorporated from Retail and Wholesale Industries, Australia: Commodities (RIS) (cat. no. 8624.0) which is conducted about every seven years. RIS is an important source of commodity weights, and the latest RIS for the 2005-06 reference year has been incorporated into the deflators from September quarter 2009 and onwards. This has resulted in revisions to the chain volume estimates from September quarter 2009 though to June quarter 2011. Further information on the introduction of updated sources of benchmark data into the ASNA can be found in the information paper: Upcoming changes to the Australian System of National Accounts, 2010-11 (cat. no. 5204.0.55.007).
Revisions to other seasonally adjusted estimates are due to the concurrent methodology for deriving seasonal factors.
