The line graph elucidates the amount of money obtained from tourist activities (in billion US dollars) in four examined areas, namely Africa, the Americas, Asia and Pacific, and Europe, between 1960 and 2010, inclusive.
Overall, all regions experienced an upward trend in revenue, with a notable increase in Asia and Pacific from the 1960s onwards. In addition, Europe consistently generated more tourism incom than other areas during the examined period, while Africa recorded the least.
In 1960, Europe generated the highest earnings from tourism at under $50 billion and grew steadily to more than $200 billion in the year 1990. This figure then experienced a sharp increase in the remaining years and reached its peak of roughly $450 billion by 2010. The Americas, beginning at a lower tourism income of around $20 billion, underwent gradual growth throughout the period, exceeding $100 billion in the early 1990s, and reaching approximately $150 billion by 2010.
Asia and Pacific exhibited a steady increase throughout the examined period. Starting at nearly $5 billion in 1960, it then witnessed a consistent surge of over $150 billion in the following years and surpassed the Americas in the early 2000s, holding the position second. Conversely, Africa was the least to generate earnings from tourism among the four regions. This figure remained lower than $100 billion throughout the period, indicating a marginal increase compared to other areas.
