Demographer Professor Sergio Della Pergola reckons that were it not for the Holocaust, there would be as many as 32 million Jews worldwide, instead of the current 13 million.
In an article soon to be published for a Yad Vashem periodical, he writes: “This was the destruction of a generation, and what we are lacking now is not only that generation, it is their children and their children.”
As a result there are relatively fewer Jews worldwide. “At present, the percentage of Jews in the world is constantly in decline. Before the Holocaust, the rate was eight Jews per thousand people in the world; today it is two per thousand.”
