The Barrier’s total length is approximately 708 km, more than twice the length of the 320-kilometre-long 1949 Armistice Line (Green Line) between the West Bank and Israel. 61.8% of the Barrier is complete; a further 8.2% is under construction and 30% is planned but not yet constructed. When completed, only approximately 15% of the Barrier will be constructed on the Green Line or in Israel. approximately 85% of its route will run inside the West Bank, isolating approximately 9.4 percent of West Bank territory, including East Jerusalem and NoMan’s Land.

By diverging from the municipal boundary, the Barrier has left some 1,600 West Bank residents isolated on the ‘Jerusalem’ side. This category consists of approximately 16 communities of mixed West Bank and Jerusalem ID card holders, (combined total 2,500).
