APPENDIX SEASONAL ADJUSTMENT OF THE CPI


SEASONALITY OF CPI EXPENDITURE CLASSES

1 The Annual Seasonal Re-analysis (ASR) reviews the seasonal adjustment of CPI series in more detail than is possible in the quarterly processing cycle.

2 Following the 2013 ASR, 57 of the 87 expenditure classes are considered seasonal (see Table 1 of this appendix) and will be seasonally adjusted for the Analytical series; 'All Groups CPI, seasonally adjusted' and 'Underlying trend series - Trimmed mean and Weighted median'. Seasonally adjusted index numbers can be found in 'TABLE 15. CPI: Expenditure Class Index Numbers, Seasonally adjusted, Weighted Average of Eight Capital Cities' and combined seasonal adjustment factors can be found in 'TABLE 16. CPI: Expenditure Class, Combined seasonal adjustment factors, Weighted Average of Eight Capital Cities'. These tables can be downloaded from the 'Downloads' tab of this issue on the ABS website <http://www.abs.gov.au>.

3 As a result of the ASR 2013, the following series is no longer seasonally adjusted:

  • Cleaning and maintenance products.

4 Changes to the seasonally adjusted series do not affect the original CPI index series.

5 Please refer to the Explanatory notes of this issue or the Information Paper: Seasonal Adjustment of Consumer Price Indexes, 2011 (cat. no. 6401.0.55.003) for more details on the seasonal adjustment of the CPI.
