ABSTRACT
Tourism demand is a broad term which we will use to cover the discussion of four more specialized topics: the factors governing levels of demand; its spatial characteristics; attempts to create typologies of different kinds of tourist activities; and tourist decisionmaking. It is also an imprecise term consisting of three main components, actual demand from those who become tourists; potential demand of those who would like to travel but cannot for reasons of time or money; and deferred demand of those who could travel but do not for some good reason. Potential and deferred categories are difficult to measure and rarely taken into account in practice, even though knowledge about them would be important in forecasting the size of future tourist developments.
