The linegraph illustrates the revenue (measured in billion US dollar) generated from tourism in four distinct regions, namely Africa, the Americas, asia and Pacific, and Europe from 1960 to 2010.
Overall, it is evident that all areas underwent an upward trend in income, with the significant growth of Asia and Pacific. In addition, Europe earned the most from tourism pratices throughout the period, while Africa generated the least.
At the start of the period, $50 billion was earned by tourism in Europe. Then this figure gradually climbed to $100 billion 20 years later, followed by a notable rise of nearly $120 billion by 1990 and reach the peak at approximately $450 billion before 2010. While in 1960, the amount of money generated form tourism in the Americas was only less than a half of Europe. It then showed gradual but continuous growth, surpassing $100 billion by 1995 and ending at roughly $150 billion by 2010.
The revenue earned by tourism in Asia and Pacific indicated a steady rise. This figure initiated at almost $5 billion in 1960 and increased gradually to $50 billion in 1990. It then experienced a significant jump to more than $300 billion by 2010, exceeded the Americas in the early 2000s. In contrast, Africa remained the least successful in tourism revenue, its figure always stay below $50 billion throughout the period, indicating the limited growth in comparision with other continents.
