What does tourism mean in the international definition?

Technical definition jon Jon: Use it to provide tourism information for statistics and legislation. The meanings or limitations provided by various definitions of tourism technology have been widely used at home and abroad. The latter method, that is, adopting technical definitions, helps to standardize the collection of comparable international tourism data. (1) 1936, which defines international tourists for the first time. During the intermission between the two world wars, the international tourism income worldwide increased rapidly, which urgently needed a more accurate definition in statistics. At an international forum held in 1936, the Committee of Statistical Experts of the League of Nations put forward for the first time that "foreign tourists refer to people who leave their habitual residence and travel to other countries for at least 24 hours". 1945, the United Nations (not the former League of Nations) accepted this definition, but added the restriction of "the maximum stay time is no more than 6 months". (2) Definition of World Tourism Organization 1963. The United Nations International Tourism Conference was held in Rome. This conference was initiated by the then International Federation of Official Tourism Organizations (IUOTO in English, now World Tourism Organization, WTO in English). The conference recommended the use of the new word "visitor". Tourists refer to travelers who leave the country where they usually live for other countries, and their main purpose is not to earn income in the country where they go. Tourists include two different types of travelers: tourists: temporary tourists who stay in the visited country for more than 24 hours for leisure, business, family affairs, tasks or meetings; Short-distance tourists: temporary tourists (including cruise tourists) who stay in the tourist destination for no more than 24 hours and do not stay overnight. Since 1963, most countries have accepted the definitions of tourists, tourists and short-term tourists proposed by the United Nations General Assembly, and have made many revisions in the future. At the 1967 Geneva meeting, the United Nations Statistical Commission proposed to establish a separate category of tourists. Visitors must stay for at least 24 hours. However, some tourists go out for sightseeing, but return to their place of residence on the same day. These people are called "short-distance travelers". Such tourists include non-employed day tourists, cruise passengers and transit tourists.
