Looking for a definition of tourism I ran into this blog post. It lists all commonly excepted definitions of the term tourism. While broad, all definitions stipulate travel away from the home area for a certain time period, not less than 24 hours. That is the minimum. A maximum however is missing in these definitions. Probably because defining a maximum time as a boundry between a tourist and a resident is more involved. Generally governments assign a 90 day maximum to tourist visas, which forms a good starting point. Generally people that receive visas for longer than 90 days receive some priviliges reserved for residents, such as the right to earn a wage through working. Naturally there is a large group of people that will still consider themselves tourists, even though they spend more than 90 days away from their home area. A good example are the thousands of backpackers roaming Australia. Character of a definition however is that it sets boundries on what falls within and outside the real of the definition. A good addition to the list of tourism definitions pointed to early therefore would be that a tourist ceases to be a tourist after 90 days, all other factors being equal.
