Today the usual weekly column of the opinion newspaper La Ragione – leAli alla liberty edited by Professor Luca Ricolfi and the Hume Foundation dedicated to the quantitative analysis of topical issues talks about the refugee emergency. According to the United Nations High Commissioner for Refugees, about 12 million Ukrainians have had to leave their homes. Among these, it is estimated that around 7 million have chosen to stay in the country by moving to regions less affected by the conflict, while as many as 5.2 million Ukrainian citizens have crossed the nation’s borders and found shelter in neighboring countries. In the graph accompanying the text, it can be seen how the number of refugees fleeing Ukraine has grown steadily since February 24, reaching the figure of 5.2 million on April 14. The majority of refugees (52.8%) crossed the North-East border and poured into Poland, while 14.1% chose Romania. Hungary, Moldova and Slovakia received 8.7%, 8.1% and 6.4% of the total refugees respectively. Finally, it is surprising (and disturbing) that almost 10% of refugees are currently in the territory of the attackers (9.4% in Russia and 0.4% in Belarus). This percentage could be explained, on the one hand, by the presence of a substantial Russian minority within the Ukrainian territory before the start of the conflict; on the other, from the strategic choice of the aggressor to open the humanitarian corridors only in the direction of his own territory. Furthermore, as reported by Ukrainian sources, there have been phenomena of real deportation of women and children to Russia.As illustrated by the third graph, the majority of refugees (4.2 million) were welcomed by the neighboring countries of the Union European (Slovakia, Hungary, Romania and Poland). To give an idea of the magnitude of these numbers, just think of the fact that in 2019 the European Union welcomed about 2.7 million people from all over the world. Assuming that immigration numbers remain constant, in 2022 the Union European Union could find itself having to accommodate nearly 7 million people including economic migrants and war refugees. The question arises spontaneously: are we ready?
