Retail Trade Survey deflator weights

The Retail Trade Survey (RTS) deflators measure change in the prices of goods and services sold by businesses in the 15 retail industries. Movements in actual retail sales values can be explained by changes in price, and by changes in volume. The deflators are used to remove the effect of price change, which allows change in the volume of retail sales to be estimated.

The deflator for each industry consists of a 'basket' of indexes, drawn mainly from the consumers price index (CPI). The CPI indexes and other indicators in each deflator's basket represent the goods and services sold by the industry. Each good or service is weighted to reflect the relative importance of the mix of goods and services sold by the industry.

The relative importance of the 41 industries that make up the 15 published retail industries is updated annually, based on sales for the latest year to June.

Current and previous RTS deflator weights are attached in the available files section of this page.

September 2010 to June 2011 quarters

In 2010, the RTS was redesigned to reflect the updated industrial classification, ANZSIC06. The RTS deflators were redeveloped to deflate estimates of retail sales in current prices from the redesigned RTS.

The ANZSIC06 deflators were directly calculated to measure price change from the June 2010 quarter onwards. Before the June 2010 quarter, the deflators were derived from backcast estimates of retail sales in current and constant prices.

September 2011 to June 2012 quarters
