Following the outbreak of civil war in Somalia, many of the country's residents left in search of asylum. According to the UNHCR, there were around 976,500 registered refugees from the nation in adjacent states as of 2016. The majority of these individuals were registered in Kenya (413,170: 326,611 in Dadaab, 54,550 in Kakuma, 32,009 in Nairobi), Yemen (253,876 in UNHCR centers and urban areas), and Ethiopia (213,775 in five camps in Dollo Ado). Additionally, 1.1 million people were internally displaced persons (IDPs). Most of the IDPs were Bantus and other ethnic minorities originating from the southern regions, including those displaced in the north. An estimated 60% of the IDPs were children. Causes of the displacement included armed violence, diverted aid flows and natural disasters, which hindered the IDPs' access to safe shelter and resources. IDP settlements were concentrated in south-central Somalia (893,000), followed by the northern Puntland (129,000) and Somaliland (84,000) regions. Additionally, there were around 9,356 registered refugees and 11,157 registered asylum seekers in Somalia. Most of these foreign nationals emigrated from Yemen to northern Somalia after the Houthi insurgency in 2015.
