Huju, two points to answer that. First, Arab Israeli birth rates have declined to witin a hairs breadth of parity with Jewish birth rates in Israel. I think its 3.17 vs 3.11. In a few years the position will have been reversed. No one is certain of the statistics of Palestinians in Gaza and Yehuda Veshomron. Anecdotally it is still higher but also declining.
The other issue is the starting point. There is great skepticism about the number of Palestinians in Yehuda Veshomron and Gaza. By many accounts the number is inflated, perhaps by more than 1 million.
So the demographic ground is shifting away from an Arab majority. How fast is hard to tell, but 10 years might show us a distinct continuing trend.
