This Paper proposes an analysis of tourism from the demand side, taking into account for both the total level of tourism demand produced by some European
countries (domestic and outgoing) and its general tendency, and for the seasonal fluctuations which characterize many tourism-related aggregates. Tourist flows from
the demand side at the European level are analyzed in the last decade, and a special focus on Italian tourism demand is provided, jointly with an analysis of its seasonal
fluctuations. The analysis of general tendency of tourism demand and of the impacts of seasonality is a fundamental pre-requisite for the implementation of tourism policies
