A traditional purely labor migration or survival or change of country to survive, you will now add others such as changing the country to live, which affects both groups of workers and students, refugees, officials, agents commercial and retirees. The migration flows are closely linked to globalization, both in global market is working and leisure, as in the redistribution of the wealth generated in rich countries, where it is sent by migrants to their places of origin, mostly in developing countries.

In a second part includes several examples of migrations illustrated with a simple mapping and representative of the different forms of migration (labor, student, retired, refugees, remittances) and migrant camps most striking, as are now the United States, Arabian Peninsula or the former USSR.
