For the 2006/07 Household Economic Survey a new expenditure classification was developed to meet the need for a common household consumption classification that better aligns with the Consumers Price Index, National Accounts and international standards. This classification is substantially different to the classfication used in the 2003/04 and earlier surveys.
The available files contain the expenditure classifications used in the 2003/04 and 2006/07 Household Economic Surveys.
