Tourism is a social, cultural and economic phenomenon which entails the movement of people to countries or places outside their usual environment for personal or business/professional purposes. These people are called visitors (which may be either tourists or excursionists; residents or non-residents) and tourism has to do with their activities, some of which imply tourism expenditure.Using this definition, we can see that tourism is not just the movement of people for a number of purposes (whether business or pleasure), but the overall agglomeration of activities, services, and involved sectors that make up the unique tourist experience.
