CPI
What is the CPI?
The Consumer Price Index ([glossary:CPI:622]) provides the official measure of inflation in Australia. The CPI is calculated by the Australian Bureau of Statistics. Movement in the CPI is measured quarterly for the three month periods ending 31 March, 30 June, 30 September and 31 December each year. The CPI figures are normally published around four weeks after the end of the quarter. The CPI is not a percentage but an index number. Any two numbers from the index can be compared to calculate a percentage change.
