The last several decades have seen a precipitous drop in the number of Jews living in Europe, according to a poll published Monday by the Pew Research Center.
The report estimated that there were 3.2 million European Jews in 1960, which fell to 2 million by 1991, and to 1.4 million in recent years.
Emigration was particularly extensive in Eastern Europe and the former Soviet Union. An estimated 3.4 million Jews lived in the European USSR in 1939. Following the catastrophic population decrease resulting from the Holocaust, the number was reduced to 2 million.
But emigration since 1945 has left 310,000 Jewish inhabitants. In Eastern European countries, the 4.7 million-strong Jewish community has dwindled to less than 100,000.
The report noted that while most of decline can be attributed to emigration to Israel, intermarriage and assimilation could also be factors.
Meanwhile, the decline appeared to be less severe in some Western European countries, whose Jewish population in 1939 was relatively smaller to begin with. About the same number of Jews live in France today as in 1939, while the number of Jews in the United Kingdom has dropped from 345,000 to 280,000.
However, the report noted recent reports of increased emigration from France, as well as new report showing a record level of anti-Semitism in the UK.
The report said 10 percent of the world's Jews live in Europe, down from 57 percent in 1939 and 35 percent in 1945.
