UNHCR (ed.). "UNHCR viewpoint: 'Refugee' or 'migrant' – Which is right?"."The majority of people arriving this year in Italy and Greece especially have been from countries mired in war or which otherwise are considered to be 'refugee-producing' and for whom international protection is needed. However, a smaller proportion is from elsewhere, and for many of these individuals, the term 'migrant' would be correct."
