In 2050, a third of Italy’s population will be foreigners, says a United Nations report. And there will be 3 seniors for each child.
From the Indo-European invasions (3rd millennium BCE) to the second half of the 20th century, the European population did not undergo demographic changes. Since 1974, in contrast, Western Europe has welcomed an Islamic immigration unprecedented in history and in the rest of the world. This change occurred at the same time as the fertility of European women plummeted below the essential threshold for generational turnover (2,1). Today in Europe there are 1.5 children per woman, which implies a division by three in the number of births in a century. In some regions (northern Italy, eastern Germany, Spain, Greece, eastern Europe) couples have on average only one child, a halving of the population over a lifetime.
