According to a recently published report of Global Commission on International Migration (GCIM), today, there are nearly 200 million migrants internationally around 60 % of which are in developed countries, and the other 40 % in developing countries. The report also acknowledges that almost one of every 10 persons living in developed countries is a migrant. The more developed regions receive each year about 2.3 million migrants coming from the less developed regions, accounting for two thirds of their population growth.
