The line chart illustrates the figure for international travellers who came to various continents in the world from 1990 to 2010.
Overall, Europe consistently had higher tourists than other regions. Meanwhile, Africa attracted the least number of tourists and fluctuated occasionally. Additionally, Asia peaked in 2005 and then decreased steadily.
In 1990, Europe began at 280 million and then increased rapidly to 400 million people; at the same time, Asia and Africa witnessed an upward trend as well. In contrast, Europe decreased slowly in 2005 but went up over time and reached a peak ( just under 500 million of international arrivals ). Furthermore, Asia rose from approximately 100 million to 200 million visitors but slightly dropped in 2010. As can be seen from the graph, Africa had the lowest level of foreign visitors compared to the remaining continents. However, the number of overseas visitors in Africa surged to roughly 75 million after fluctuating.
