Refugees and asylum seekers are especially vulnerable to homelessness and poor housing. In the developing world, the mass influx of refugees and the resulting large refugee camps raise serious concerns. Despite most refugees emanating from the developing world and remaining in their region of origin, the minority of refugees who travel to the developed world face an increasing range of barriers to entry and restrictions upon their access to housing. It is alleged that some states in the developed world use the threat of destitution as a means of discouraging (unmeritorious) applications and forcing unsuccessful applicants to return to their state of origin. Both international refugee law and international human rights law are sources of rights that may assist displaced peoples at risk of homelessness, but asylum seekers and refugees remain vulnerable.
