Tourism
Definitions

In 1936, the League of Nations defined a foreign tourist as "someone traveling abroad for at least twenty-four hours". Its successor, the United Nations, amended this definition in 1945, by including a maximum stay of six months.

In 1941, Hunziker and Kraft defined tourism as "the sum of the phenomena and relationships arising from the travel and stay of non-residents, insofar as they do not lead to permanent residence and are not connected with any earning activity." In 1976, the Tourism Society of England's definition was: "Tourism is the temporary, short-term movement of people to destinations outside the places where they normally live and work and their activities during the stay at each destination. It includes movements for all purposes." In 1981, the International Association of Scientific Experts in Tourism defined tourism in terms of particular activities chosen and undertaken outside the home.

In 1994, the United Nations identified three forms of tourism in its Recommendations on Tourism Statistics:

Other groupings derived from the above grouping:

The terms tourism and travel are sometimes used interchangeably. In this context, travel has a similar definition to tourism but implies a more purposeful journey. The terms tourism and tourist are sometimes used pejoratively, to imply a shallow interest in the cultures or locations visited. By contrast, traveller is often used as a sign of distinction. The sociology of tourism has studied the cultural values underpinning these distinctions and their implications for class relations.

There are many varieties of tourism. Of those types, there are multiple forms of outdoor-oriented tourism. Outdoor tourism is generally categorized into nature, eco, and adventure tourism (NEAT). These categories share many similarities but also have specific unique characteristics. Nature tourism generally encompasses tourism activities that would take place outside. Nature tourism appeals to a large audience of tourists and many may not know they are participating in this form of tourism. This type of tourism has a low barrier to entry and is accessible to a large population. Ecotourism focuses on education, maintaining a social responsibility for the community and the environment, as well as centering economic growth around the local economy. Weaver describes ecotourism as sustainable nature-based tourism. Ecotourism is more specific than nature tourism and works toward accomplishing a specific goal through the outdoors. Finally, we have adventure tourism. Adventure tourism is the most extreme of the categories and includes participation in activities and sports that require a level of skill or experience, risk, and physical exertion. Adventure tourism often appeals less to the general public than nature and ecotourism and tends to draw in individuals who partake in such activities with limited marketing.

It is important to understand that these definitions may vary. Perceived risk in adventure tourism is subjective and may change for each individual.
