The survey on the travel behaviour of the Austrian resident population records the number and profile of trips made in Austria and abroad within a quarter (e.g. purpose of travel, choice of means of transport, travel destination, expenditure). The socio-demographic profile (e.g. gender, age) of travellers and non-travellers is also collected. For this purpose, about 3 500 people per quarter are interviewed online or by telephone. The results are updated quarterly and serve to evaluate the economic importance of tourism and are the basis for tourism policy decisions. Internally, the data flows into the calculations of the travel balance of payments and the tourism satellite account (TSA).
