The following χάρτης shows the volume of international calls between the countries of the world that took place over a year.
The image comes from a research conducted by DHL and titled "Global Connectedness Index 2014". The index finger he records the levels of globalization and how these change from year to year. One of this year's conclusions is that global cohesion, which depends on cross-border flows that show the exchange of products, capital, information and people, has recovered most of the damage it suffered during the financial crisis.
With an analysis of data arising from this research, one can draw several conclusions. One of them is that 41% of international calls originate from developed economies and end up in developing ones. Only 9% follow the reverse path. In part, this phenomenon can be explained in two ways.
On the one hand, we see which countries most often choose immigrants. See, for example, the relationship between the US and Mexico. On the other hand, in a developed country, the cost of international calls is much lower than in a developing country. So the first group of citizens has more financial comfort to call a relative belonging to the second group of citizens.
This map, of course, does not reveal to us how rarely someone calls in another country. The researchers who created it report that if we add up all the minutes that people spend on international calls, we will see that they correspond to only 3% to 4% of the total time spent on calls.
Here is a different way to represent the data of the above map. Click on the image to see it in higher resolution.
