The UN factbook says the ferility in Gaza is the highest in the world, about 7, and around 5 or so on the West Bank. Maybe it is wrong, but I doubt if it is that wrong. Plus, Israel is going to get relatively rather few Jewish immigrants going forward. They have sucked that well rather dry.
From the press release:
The research team discovered:
Fewer births: PA Ministry of Health birth reports were substantially lower than the number predicted by the PBS.
Lower Fertility Rates: Palestinian fertility rates declined from the mid-90’s through 2003, according to PA Ministry of Health, consistent with the trend occurring in other Middle Eastern Arab societies.
Net Emigration: Instead of the large immigration originally projected by the PA, the Territories experienced a steady net emigration averaging 10,000 a year.
Double Counting: 210,000 Jerusalem Arabs who are already counted in Israel’s population survey were included in the PA survey.
Inclusion of non-residents: Palestinians with IDs living abroad for over one year were included in the PA Census & Projection.
Internal migration: 150,000 PA Arabs who have legally relocated to Israel since 1993 are still counted by the PA..
Don't count Jewish immigration out totally. In 10 years there will be more French Jews in Israel than in Paris. Much of the rest of European Jewry will be looking towards the US or Israel as the creation of Eurabia chases Jews out.
