The vast majority of Syrians who've fled to Jordan and Lebanon have become "Urban Refugees."

Almost all Syrian refugees in Jordan are currently living in urban areas, clustered near the border.

Syrian refugee Fawaz now lives in Jordan with his wife and nine children in a two room structure that had been abandoned for years before they found it. The roof leaks, and while there's a makeshift toilet, there's no plumbing. They've tapped into a neighbor's utilities for electricity and drinking water. There's very little housing left in Jordan near its border with Syria, and rental prices have more than doubled in the past year due to the influx of refugees.
