Migration is a significant global challenge for public health in the 21st century. The International Organization on Migration (IOM) estimates that one in thirty-five people in the world are migrants. Reasons for migration are multifarious, involving any kind of movement of populations, with direct implications for the health of migrants and health systems alike. Internal migration such as rural-to-urban migration, cross border migration in increasingly transnational societies, and international migration in an age of a global economy are all distinct areas for public health research.
As a global health issue, at the root of migration is social, political and economic development. This is seen in migrant communities throughout the world, from factory cities in mainland China to new Latino immigrant communities in the United States. From a global perspective migration not only affects how individuals access health services but has implications on a wider scale: health security, infectious disease, health equity, health policy and law, provision of primary care, and the environment. Intergenerational research of migrants ensure that migrant health is long-term and interdisciplinary topic.
This special issue uses different global perspectives to shed light on major challenges of immigrant health and solutions in developing and developed countries alike. Implications for health systems and policy and a wider lens of the global economy will be examined and shared.
