The map above shows the Jewish population of Europe in both 1933 and 2015 by country. Most countries still had much lower Jewish populations in 2015 compared to 1933.
This is largely due to the long lasting effects of The Holocaust, when over six million European Jews were systematically murdered by Hitler and the Nazis.
Emigration to both Israel and the United States after World War 2 and again after the collapse of Communism in Eastern Europe in 1989, also contributed somewhat to the decline.
However, not all countries saw their Jewish population decrease.
