The aim of the business tendency survey is to provide rapid, qualitative indications of the outcome, the current situation and expectations for important economic variables, where there is as yet no quantitative information. The questions concern, for instance, whether the inflow of orders has increased, remained unchanged or declined. The graphs show balances, i. e. the proportion responding "increase" minus the proportion responding "decline".
The confidence indicator for construction industry is based on the answers to several questions, according to the formula
Confidence indicator = order books + number of employed, expectations.
