The 28 July 2012 edition of The Economist has a Special report on Judaism and the Jews
From this we learn:
1. 57% of the word's 'Jews' live outside of Israel.
43% live in Israel.
There are 13,580,000 'Jews' in the world.
5,275,000 Jews live in the USA.
5,703,000 Jews live in Israel.
Some of the Israeli population came from North Africa and various countries in the Middle East.
The Khazar were a Turkic tribe. They converted to the Jewish religion. Khazaria: A Forgotten Jewish Empire | History Today. Many of the Israelis are Khazars.
2. According to J.J. Goldberg, a writer, "Celebrities used to change their names to hide their Jewish identity.
"Now they talk on television about how they try to instil Jewish identity into their half-Jewish children.
"Take (the actress) Gwyneth Paltrow. Her father is a descendant of rabbis; her mother is a Protestant from middle America. She writes in her food blog about her favourite kosher recipes..."
3. In Russia and Ukraine, Jews are prominent in business.
4. When Hitler came to power, some 6m Jews were safe in North and South America and in Britain, with 3m more living in the Soviet Union.
5. Zionism, the movement for Jewish independence in Palestine, had to struggle for Jewish popular support.
The Ultra-Orthodox Jews were originally opposed to Zionism, and some still are.
The Modern-Orthodox Jews are strongly in favour of Zionism.
The growing Modern-Orthodox settler movement in the West Bank supports permanent occupation of the West Bank.
The Conservative Jews are in favour of Zionism but relatively few have gone to live in Israel.
The Reform Jews were originally opposed to Zionism and relatively few have moved to Israel.
As their link to Judaism weakens, so does their support for Israel.
