The Ai Group Industry Index is a monthly diffusion index based on a survey of several hundred businesses across Australia's manufacturing, services, and construction sectors. It provides an early snapshot of industrial activity, with readings above 50 indicating expansion and below 50 indicating contraction. It is highly regarded as a leading indicator of broader economic trends in Australia.
The index is calculated from survey responses regarding production, new orders, employment, and deliveries. The net balance of positive and negative responses is used to create the diffusion index value.
