The index has the following sub-components: Activity/Sales, Employment, New Orders, Input Volumes, Input Prices, Selling Prices, Wages, Exports (excluding for Construction), and Capacity Utilisation.
The indicators report on a scale of -100 to 100. Any value below 0 signifies contraction in the sector/component, and any value above 0 signifies expansion. The distance from 0 indicates the strength: 20 is expanding faster than 10.
Time series data can have seasonal variations. For example, you would expect lower factory output over the summer break in December/January. Seasonally adjusted data lets us identify underlying changes in business activity that are not accounted for by seasonal factors. We follow Australian Bureau of Statistics methodology to make seasonal adjustments.
Timeseries variables can have peaks and troughs, which are often one-off events that don’t necessarily characterise the long-run pattern in an industry. Trend data allows us to get a more even look of the variable and to minimise these extremes or outliers. We use the Henderson-13 technique to trend Aii data.
The Aii was launched in January 2023, however, we back implemented the index up to 2017 for raw data (to compute seasonal adjustments and assign a structural break for COVID-19). Seasonally adjusted data is available from January 2020, and trend data from July 2020.
The use of the data would be subject to the terms and conditions of your subscription, please refer to said terms or contact economics@aigroup.com.au for a more detailed discussion.
The data is collected through a monthly survey that is open to any Australian business in its included sectors. The survey is confidential, the data de-identified and only reported in aggregate. It is not anonymous - we verify participants, their geographic location and industry sector.
