4.104. As observed in Chapter III with respect to international comparability, UNWTO collects information annually from countries and territories all over the world.

4.105. Regarding inbound and outbound tourism expenditure, because some countries still do not compile tourism data, UNWTO uses data as much as possible from the Balance of Payments rather than tourism data to support international comparisons. Nevertheless, Balance of Payments data however useful in this regard, should not be used in the overall tabulation of tourism statistics and should never be considered a substitute for tourism statistics. It is expected that, in time and as countries develop their Systems of Tourism Statistics, it will become possible to collect those countries’ actual inbound and outbound tourism expenditure data.
