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 1994, the United Nations identified three forms of tourism in its Recommendations on Tourism Statistics; these are:-
• Domestic tourism, involving residents of the given country traveling only within this country
• Inbound tourism, involving non-residents traveling in the given country
• Outbound tourism, involving residents traveling in another country
The World Tourism Organization defines tourism as "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes.
Tourism brings large amounts of income into a local economy in the form of payment for goods and services needed by tourists. It also generates opportunities for employment in the service sector of the economy associated with tourism.
The hospitality industries which benefit from tourism include transportation services, lodging, and entertainment venues. This is in addition to goods bought by tourists, including souvenirs.
On the flip-side, tourism can degrade people and sour relationships between host and guest
