The Westpac - Melbourne Institute Survey of Consumer Sentiment index has been designed as a trend-less variable that provides an indication of the level of and shifts in consumer sentiment over time. The index is an average of five component indexes which in turn reflect the balance of favourable and unfavourable responses to five survey questions. These questions relate to family finances a year ago and in the next 12 months, economic conditions in the next 12 months and next 5 years, and good or bad time to buy major household items. An index level of 100 indicates that the balance of confidence or optimism is equally weighted, while an index of greater than 100 indicates that optimists outnumber pessimists. Please note that from June 2006, the seasonally adjusted series is discontinued as statistical tests indicated no significant evidence of seasonality. News stories present seasonally adjusted figures which were resumed in February 2007.
