The Barrier in the Jerusalem area has transformed the geography, economy and social life of East Jerusalem and its wider metropolitan area. In the areas where it follows the Israeli-defined municipal boundary, the Barrier physically separates Palestinian communities onto either side of what had previously been only a jurisdictional division. Thus, some Jerusalem suburbs that were once closely connected to the city are now walled out, with previously flourishing residential and commercial centres closing down, and families being forced to leave to areas with better access to services and livelihoods.
