The recent fatal shooting at the Jewish Museum in Brussels may increase the probability of more Jews leaving Belgium. Belgium is already one of the countries with the highest rates of aliyah to Israel.
In 1948, there were 34 countries with over 25,000 Jews. Today, there are HALF -17 countries. Belgium (30,400) and Italy (28,000) are the next countries that are likely to see their Jewish populations drop below 25,000.
Over 82% of the Jews in the world are concentrated in only two countries – Israel and the US – the greatest concentration of Jews in 2000 years.
