According to the UNHCR, the Middle East and North Africa region remains one of the largest hosts of refugees and migrants in the world. Millions are displaced by conflict and economic hardship, and the region accounts for about 14% of the global migrant population. The Pew Research Centre also reports that the Middle East’s migrant population more than doubled between 2005 and 2015, increasing from 7% to 13% of the total regional population. Labour migration, mainly from South Asia, is a key factor in this rise.
