Answer:
In 2011 according to CBS there were 327,750 Israelis living in the west bank and an additional 190,000 living in East Jerusalem.
The combined growth rate for the Jewish population in these areas was 5.2% and has been stable for the past 20 years, whereas the Arab population of the west bank grows at the rate of 2.0%.
By these projections the Jewish population is set to become the majority in the West Bank within 45 years
