This report describes the arbitrary exclusion by the Israeli military of hundreds of thousands of Palestinians since 1967 and documents the impact that exclusion continues to have on individuals and families. The way Israel's military has exercised its control over the Palestinian population registry -- the list of Palestinians whom it considers to be lawful residents of the West Bank and Gaza territories -- has separated families, caused people to lose jobs and educational opportunities, barred people from entering the Palestinian territories, and trapped others inside them. Egypt also has problematic policies on Palestinians trying to enter Gaza that are based on the Israeli-controlled population registry.
