Tourism is travel for recreational, leisure or business purposes. Tourism has become a popular global leisure activity. In 2008, there were over 922 million international tourist arrivals, with a growth of 1.9% as compared to 2007. International tourism receipts grew to US$944 billion (euro 642 billion) in 2008, corresponding to an increase in real terms of 1.8%.
There has been an upmarket trend in the tourism over the last few decades, where international travel for short breaks is common. Tourists have high levels of disposable income, considerable leisure time, are well educated, and have sophisticated tastes. There is now a demand for a better quality products, which has resulted in a fragmenting of the mass market for beach vacations; people want more specialised versions, quieter resorts, family-oriented holidays or niche market-targeted destination hotels.
The developments in technology and transport infrastructure, such as jumbo jets, low-cost airlines and more accessible airports have made many types of tourism more affordable. WHO estimates that up to 500,000 people are on planes at any time. There have also been changes in lifestyle, such as retiree-age people who sustain year round tourism. This is facilitated by internet sales of tourism products. Some sites have now started to offer dynamic packaging, in which an inclusive price is quoted for a tailor-made package requested by the customer upon impulse.
