Certainly I was writing a more complete article about migration, but I can't just pas this wonderful chart up. The chart represent global migration and it was developed by geographers Guy J. Abel and Nikola Sander. It is a clear example of our inter-conected world and culture relations, and remark the importance of cultural diversity understanding. But be aware, migration isn't a new phenomena, big migrations had happened through all human history, and one of big migrations happened during XV and XX by europeans.
This Chart is unique in the way that represent migration. Degrees on the circle represent total mobile population while lines are population flow. Two things to put out of your mind, migrants are not necessarily poor people and many are students getting degrees or profesionals and businessmen looking for new business and markets.
First general observations
Two things. The biggest population flow is between South Asia and Middle East, probably because huge investment on energy in that place. Second, biggest flow among two countries is Mexico-USA, this cause of labor and economic relations. This is very important to get understanding of global economy and it base on internationalization of labor relations and social cost.
