The given line graph illustrates the variation in international tourists arrivals in different parts of the world, such as North America, some parts of Europe and Asia, Sub-Saharan Africa and south America. All the data refer to a gap of time from 1990 to 2005.
Overall, the most striking aspect is that all the regions expericed an upward trajectory, exeption made for North America that, in its final part, remained relatively constant with a slight negative tendecy. Moreover, most of the zones started with different amounts of turists in the area.
North america is clearly the most visited region of the group, indeed in 1990, nearly 70 million people visited this area. Starting from that amount, the curve began its growth, reaching its peak in 2000 with more than 90 million turists. By contrast, South America and Sub-Saharan Africa are the two places less visited. These curves have similar trends: in 1990 South America initially exceeded Africa, nevertheless, it experienced during the years a continuous growth untill 2005 recording roughly 25 million visitors. This aspect caused a shift in the initial situation with South America that had a minor increase in comparison with Africa, indeed, in 2005 turists in this zone were almost 15 million.
Lastly, central and east Europe, are the areas with the most steep increase during the time: people in these areas approached 31 million in 1990. Subsequently, the amount of visitors leapt until 2005 in which they almost reached the same amount of the ones in North america, that is more or less 90 million.
