About 3.2 per cent of the world population are international migrants, compared to 2.8 per cent in 2000. The share of international migrants in total population varies considerably across development groups and major areas. Thus, international migrants represent 10.8 per cent of the total population in the developed regions compared to 1.6 per cent in the developing regions. Oceania (20.7 per cent), Northern America (14.9 per cent) and Europe (9.8 per cent) record the highest proportions of international migrants in total population.

By the end of 2012, the world hosted an estimated 15.4 million refugees and persons in refugee-like situations.

Over 87 per cent of all refugees (13.4 million) had found asylum in developing countries. Asia hosted the largest number of refugees (10.0 million), followed by Africa (3.1 million) and Europe (1.5 million).
