APPENDIX 1 ANALYTICAL PRICE INDEX SERIES
INTRODUCTION
1 Various series are presented in Table 8 of the Consumer Price Index, Australia (cat. no. 6401.0) to assist users analyse the CPI. As a result of the introduction of the 16th series Australian CPI, there have been some changes to the groups, sub-groups and expenditure classes contributing to each of the analytical series. Some of the compiled series are self-explanatory, such as 'All groups CPI excluding Food and non-alcoholic beverages'. This appendix describes the composition of some of the other analytical series - goods and services, international trade exposure and seasonally adjusted - in the 16th series Australian CPI. The following table (Table 1) sets out the 87 CPI expenditure classes showing in which analytical series they are included.
GOODS AND SERVICES
2 The ABS has classified expenditure classes as goods or services based on the majority of products in each category. In the 16th series CPI, 60 out of the 87 expenditure classes, accounting for 58 per cent of the All groups CPI by weight, have been classified as goods. The remaining 27 expenditure classes, accounting for 42 per cent of the All groups CPI by weight, have been classified as services.
INTERNATIONAL TRADE EXPOSURE - TRADABLES AND NON-TRADABLES
3 For the 16th series, the tradable and non-tradable classification was reviewed and updated using 2006-07 Input-Output data to classify each expenditure class as tradable or non-tradable. As a result, there were five changes to the classification: 'Cakes and biscuits' and 'Jams, honey and spreads' were reclassified from non-tradable to tradable while 'Waters, soft drink and juices', 'Newspapers, magazines and stationery' and 'Pets and related products' were reclassified from tradable to non-tradable.
4 In aggregate, 47 expenditure classes, accounting for approximately 40 per cent of the CPI by weight, have been classified as tradable. The remaining 40 expenditure classes, accounting for approximately 60 per cent of the CPI by weight, have been classified as non-tradable.
5 The method used to classify the 16th series expenditure classes is set out below:
- Data from the National Accounts Input-Output Tables 2006-07 and the related product correspondence with the 16th series Consumer Price Index Commodity Classification were used to calculate Australia's exports as a ratio of total Australian production and imports as a ratio of total usage, for each expenditure class. The correspondence will be available in Australian National Accounts: Input-Output Tables - Electronic Publication (2007-08 Final) (cat. no. 5209.0.55.001), released on 25 October 2011;
- All expenditure by international tourists in Australia was excluded from exports, as their expenditure on items such as urban transport fares was deemed not to affect price change;
- Expenditure classes were classified as 'tradable' if either of the export or import ratios were greater than 10 per cent;
- The remaining expenditure classes were classified as non-tradable.
SEASONALITY OF CPI EXPENDITURE CLASSES
6 The 16th series seasonal adjustment review used a range of statistical tests to determine if seasonality was present in each expenditure class price index. This approach identifies series that show seasonal patterns over any part of the series to be seasonal. Using this ABS seasonal adjustment methodology, 62 of the 87 expenditure class price indexes in the 16th series of the CPI were deemed to have a seasonal pattern.
