We welcome the UCL–Lancet Commission that highlights migration as a key determinant of health, and rightly examines the discrimination and denial of access to health services faced by many migrants. The Commission emphasises the diversity of migrant experiences, sheds light on the record on migrant health, and draws attention to the positive economic impact of migration. Here we draw attention specifically to the health needs of refugees and the internally displaced people (IDP) who are forced to flee by conflict or disaster.
The latest UN figures show that an unprecedented 68·5 million people were displaced by conflict or disaster at the end of 2017, of whom 53% were children. 25·4 million of these people are refugees, and 40 million are IDP. Most of these people, over 85%, live in low-income and middle-income countries (LMICs). Of refugees, around 60% live in urban areas and not in camps that are the stereotype of the refugee experience.
