Survey responses reflect the change, if any, in the current month compared to the previous month based on data collected mid-month. For each of the indicators the ‘Report' shows the percentage reporting each response, the net difference between the number of higher/better responses and lower/worse responses, and the ‘diffusion' index. This index is the sum of the positive responses plus a half of those responding ‘the same'. Diffusion indexes have the properties of leading indicators and are convenient summary measures showing the prevailing direction of change. An index reading above 50 indicates an overall increase in that variable, below 50 an overall decrease.
