The Oslo II Accord divided the West Bank into three administrative divisions: Areas A, B and C. The distinct areas were given different statuses, according to their governance pending a final status accord: Area A is exclusively administered by the Palestinian Authority; Area B is administered by both the Palestinian Authority and Israel; and Area C, which contains the Israeli settlements, is administered by Israel. Areas A and B were chosen in such a way as to just contain Palestinians, by drawing lines around Palestinian population centers at the time the Agreement was signed; all areas surrounding Areas A and B were defined as Area C.
Area A comprises approximately 18% of the West Bank and Area B about 22%, together home to some 2.8 million Palestinians. As of 2015, Area C is home to 150,000 Palestinians in 532 residential areas. It is also home to 389,250 Israelis, in 135 settlements, as well as 100 outposts unrecognized by the Israeli government. Area C forms a contiguous territory, administered via the Judea and Samaria Area administration. In contrast, under the Oslo Accords Areas A and B were subdivided into 165 separate units of land that have no territorial contiguity.
The Oslo II Accord stipulated that "during the first phase of redeployment" the jurisdiction over Areas A and B would be transferred to the Palestinian Council. Article XI.2.a reads:
"Land in populated areas (Areas A and B), including government and Al Waqf land, will come under the jurisdiction of the Council during the first phase of redeployment."
The populated areas were defined by delineations on a map attached to the document. Area C comprised the areas of the West Bank outside Areas A and B.
Area A (full civil and security control by the Palestinian Authority): initially, circa 3% of the West Bank, exclusive East Jerusalem (first phase, 1995). As of 2013, Area A formally comprised about 18% of the West Bank. The Israel Defense Forces, however, abolished the prohibition against entering Area A during Operation Defensive Shield in 2002 and enters the area regularly, mostly at night, to conduct raids to arrest suspected militants. This area includes eight Palestinian cities and their surrounding areas (Nablus, Jenin, Tulkarem, Qalqilya, Ramallah, Bethlehem, Jericho and 80 percent of Hebron), with no Israeli settlements. Entry into this area is forbidden to all Israeli citizens.
