From a Washington Post article about Iraqi refugees driven to prostitute themselves, we have this:
Impoverishment is also the main factor driving refugees to return home — about 1,500 a day are crossing back into Iraq, compared to up to 500 daily arrivals, the UNHCR says.
A survey in November showed 46 percent were returning due to financial hardship and 26 percent because their visas had run out — Syria has recently tightened entry and residence rules.
I had been wondering why so many Iraqis were returning home, because it didn’t seem to me that it was any more stable or safe than it had been for years. Now I know why.
