Over the centuries, migration has always been, to some extent, a feature of human populations, with people migrating and crisscrossing the globe for a wide range of reasons. In recent times, particularly during the 21st century, there have been significant increases and changes in international migration and resettlement patterns due to factors such as people’s ability to travel, ease of communication and technology, civil unrest and conflicts. As a result of these factors, global populations have increased and integrated across settings, challenging the differentiation between types of migrants such as refugees (those migrating because of factors such as civil unrest, wars, persecution or other vulnerability) and economic migrants.

This mixture of migration and resettlement patterns will continue for generations and due to these diverse, multicultural and complex communities, we will need more research to provide evidence to inform nations and global responses to any emergences. This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) focuses on a number of thematic areas, including, but not limited to:

• Health literacy and communication

• Mental health and resilience

• Sexual and reproductive health services

• Identity and belongingness 

• Policy for disability among migrants in Europe
