Art - This may give you a more accurate picture:

According to Wiki - "Jewish 80.1% (Europe/America-born 32.1%, Israel-born 20.8%, Africa-born 14.6%, Asia-born 12.6%), non-Jewish 19.9% (mostly Arab) (1996 est.)"

You have to remember that although those born in Israel are considered to be Israeli born, it doesn't mean their parents were from Israel. In fact, European immigration to Israel is very high.

I'd like to know exactly how many of Israel's Jews were actually born in the Middle East.
