Answer: Their population sank, even after Holocaust attacks and rates of homelessness among the Jewish Community were prevalent. Even today, there are currently people who identify as Nazi's, deny the holocaust happened or had the effects it had as well as verbal and online antisemitism (hostility to or prejudice against Jewish people) and hate crimes.
Explanation: Six million Jews died in the Holocaust. After liberation, many Jewish survivors feared to return to their former homes because of the antisemitism (hatred of Jews) that persisted in parts of Europe and the trauma they had suffered. Some who returned home feared for their lives. In postwar Poland, for example, there were a number of pogroms (violent anti-Jewish riots). The largest of these occurred in the town of Kielce in 1946 when Polish rioters killed at least 42 Jews and beat many others. (ushmm.org)
