The frequency of price collection by item varies as necessary to obtain reliable price measures. Prices of some items are volatile (i.e. their prices may vary many times each quarter) and for these items frequent price observations are necessary to obtain a reliable measure of the average price for the quarter.

The CPI uses a hierarchy of rounding procedures to ensure consistency between published index numbers and percentage changes. However, rounding differences can arise in points contributions because of the different levels of precision required in those data.

Movements in indexes from one period to another can be expressed either as changes in index points or as percentage changes. An example cited in paragraph 8 of the Explanatory Notes illustrates the method of calculating changes in index points and percentage changes between any two periods. Comparing the headline figure to other countries is often inappropriate because of different measurement approaches used by countries for certain products. The index excluding housing and financial services is a better basis for international comparisons.

Consumer Price Index (CPI) 17th SeriesAbstract

The Consumer Price Index (CPI) measures quarterly changes in the price of a 'basket' of goods and services which account for a high proportion of expenditure by the CPI population group (i.e. metropolitan households).

Statistical population

Australia and major capital cities.

Geographic coverage

The index covers private household expenditure in the eight State and Territory capital cities.

Item coverage

The 'basket' (see Abstract) covers a wide range of goods and services arranged in the following eleven groups: Food and non-alcoholic beverages, Alcohol and tobacco, Clothing and footwear, Housing, Furnishings, household equipment and services, Health, Transport, Communication, Recreation and culture, Education, Insurance and financial services.

Other coverage

Various series are also presented which are helpful for analytical purposes. Refer to paragraphs 11 to 12 of the Explanatory Notes for a description of these series

Key statistical concept

Indices shown for Consumer Prices are the most frequently used indicators of inflation and reflect changes in the cost of acquiring a fixed basket of goods and services by the average consumer.

Index type

The capital city indexes measure price movements over time in each State and Territory capital city individually. They do not measure differences in retail price levels between cities.

Weights

There are 87 expenditure classes (grouping of the like items) in the 17th series CPI and each expenditure class has its own weight, or measure of relative importance. In calculating the index, price changes for the various expenditure classes are combined using these weights. The current and historical weighting patterns for the CPI for the weighted average of the eight capital cities is published in Consumer Price Index: Historical Weighting Patterns (cat. no. 6431.0), available on the ABS website.

Seasonal adjustment

Seasonally adjusted numbers are only available for the Weighted average of 8 capital cities, not for the individual capitals. The seasonal adjustment methodology is described in Seasonal Adjustment of Consumer Price Indexes, 2011 (cat. no. 6401.0.55.003).
