APPENDIX 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. This appendix describes the composition of the analytical series - goods and services, international trade exposure and seasonally adjusted - in the Australian CPI. Table 1 shows in which of the analytical series the 87 CPI expenditure classes 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 CPI, 60 out of the 87 expenditure classes, accounting for approximately 56 per cent of the All groups CPI by weight, have been classified as goods. The remaining 27 expenditure classes, accounting for approximately 44 per cent of the All groups CPI by weight, have been classified as services.
INTERNATIONAL TRADE EXPOSURE - TRADABLES AND NON-TRADABLES
3 The tradables and non-tradables classification was reviewed and updated in the December quarter 2016 using 2013-14 Input-Output data to classify each expenditure class as tradable or non-tradable. As a result, there were eight changes to the classification: Breakfast cereals; Waters, soft drinks and juices; Gas and other household fuels; Therapeutic appliances and equipment; and Newspaper, magazines and stationery were reclassified from non-tradables to tradables: and Spirits; Tobacco; and Pharmaceutical products were reclassified from tradables to non-tradables.
4 In aggregate, 49 expenditure classes, accounting for approximately 35 per cent of the CPI by weight, have been classified as tradables. The remaining 38 expenditure classes, accounting for approximately 65 per cent of the CPI by weight, have been classified as non-tradables.
5 The method used to classify the series expenditure classes is set out below:
- Data from the National Accounts Input-Output Tables 2013-14 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 is available in table 40 of Australian National Accounts: Input-Output Tables, 2013-14 (cat. no. 5209.0.55.001);
- 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 'tradables' if either of the export or import ratios were greater than 10 per cent;
- The remaining expenditure classes were classified as 'non-tradables'.

MARKET GOODS AND SERVICES EXCLUDING 'VOLATILE ITEMS'
7 Market items are those available on the open market. The volatile items are Fruit, Vegetables and Automotive fuel.
SEASONALITY OF CPI EXPENDITURE CLASSES
8 Seasonal adjustment uses a range of statistical tests to determine if seasonality is 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 ABS seasonal adjustment methodology, 58 of the 87 expenditure class in the CPI are deemed to have a seasonal pattern in the current period. For more details on the seasonal adjustment of the CPI please refer to Information Paper:
Seasonal Adjustment of Consumer Price Indexes, 2011 (cat. no. 6401.0.55.003).
