Performance Indices

Australian Industry Group Economic Performance Indices

Each month Ai Group releases performance indices for the manufacturing, services and construction sectors. These national composite indices are compiled through surveys of firms, conducted on a representative sample basis. They are seasonally adjusted and based on the diffusion indexes of key indicators including sales & activity, new orders, supplier deliveries and employment, with varying weights.

An index reading above 50 points indicates activity is generally expanding; below 50, that it is declining. The distance from 50 is indicative of the strength of the expansion or decline.

From October respondents to the PSI will have the opportunity to receive a free individualised ‘report card’ that will enable them to compare their responses to the PSI survey to the aggregate responses of businesses in your industry.

To construct the indices, survey respondents are asked to specify for each question whether their activity for that topic (i.e. new orders) has either increased ("up"), decreased ("down") or remained the same ("no change") from the previous month’s level.
