Antwerp is a unique case within the context of the Holocaust in Belgium. Harbouring the largest part of the Jewish population at the end of 1940 (52,94 % of all Jews registered in Belgium), Lieven Saerens’ research on the persecution of Jews in Antwerp led to the coining of the term 'the Antwerp specificity' as he had calculated that 65 to 67 percent of Antwerp's Jewish population was deported in comparison to the Belgian average of 45 percent.
