My friend Yoram Ettinger,who served as Congressional liason for the Israeli Embassy in Washington, has published an interesting JP op-ed on demographics in Israel.He has written and spoken extnsively on this topic.
Using UN statistics,he shows that there is an "implosion" in Muslim Societies.This is a derivative of modernization,Westernization,urbanization and local political factors.
The lowering of the Arab birth rate within the "Green Line" from 9 births per woman in 1969 to 3.5 in 2007 is significant.
Jewish births have increased from 69% of total births to 75% in 2007.Thus, demographic trends "bode well for solid Jewish majorities within the "Green Line".
In Judea Samaria,the Jewish population in 1947 was 8%, and now 33%".
