What's Changing? - Migration


The United Nations High Commissioner for Refugees issues an annual report concerning the approximately 21 million people worldwide falling under its mandate: refugees forced to leave their countries due to war, political, racial or religious persecution, as internally displaced persons, or as repatriates on their way back home.  An interactive visualisation gives an insight into the flows and connections of global flight and expulsion.

As Western populations live ever longer, they will need more nurses, care assistants, housekeepers and cleaners. The demand for highly skilled workers will therefore grow too, and countries will start to compete more fiercely for mobile talent. Migration will “define our future” , claimed the authors of a recent book.

DNA tests on almost 1,000 people have shown all non-Africans are related to a single population that migrated from Africa between 80,000 and 50,000 years ago.The research, published in the journal Nature, details how geneticists took DNA samples from people of different cultures in different parts of the world. They then traced back their genetic links through the millennia. All arrived at the same conclusion.This animated video, produced by the University of Hawaii, shows the spread of the human race across the globe over a 125,000 year period.
