There has been a surge in international migration in recent years, reaching a total of 244 million individuals in 2015. Forced displacement has also reached a record high, with 65.3 million individuals displaced worldwide by the end of 2015 – including refugees, IDPs and asylum seekers. Yet while the absolute numbers have increased over the last 15 years, migrants as a percentage of total global population has remained stable at about three percent. A majority of migrants remain on their own continents – nearly nine out of ten African migrants settle on the African continent, while eight out of ten Asian migrants remain in Asia. Forced displacement is predominantly an issue outside wealthy economies:
nine out of ten refugees are hosted by low and middle-income countries.
On 12 May 2016, the Norwegian Refugee Council (NRC) through its Internal Displacement Monitoring Centre (IDMC) launched its annual publication “The Global Report on Internal Displacement (GRID)”, identifying climate change and related natural hazards, such as droughts, sea-level rise and desertification as increasingly important factors causing internal displacement.
