The West Bank is a landlocked territory on the west bank of the Jordan River in the Middle East. Since 1967 most of the West Bank and Gaza Strip has been under Israeli military occupation. In 1993, the Oslo accords declared both West Bank and Gaza Strip to be partially under the administration of the Palestinian National Authority (PNA). Before 1967 there were no universities in the West Bank. Since there were no universities in West Bank at that time, Palestinians could obtain degrees only by travelling abroad to places such as Jordan, Lebanon, or Europe. After 1967, several educational institutions began offering undergraduate courses, while others opened up as entirely new universities. In December 2007, an official Census conducted by the Palestinian Authority found that the Palestinian population of the West Bank (including Israeli-annexed East Jerusalem) was 2,345,000. In terms of health insurance, more than half of the Palestinian population have governmental insurance and can obtain medications from governmental medical centers.
