Il Wittgenstein Centre for Demography and Global Human Capital ha analizzato i flussi migratori nel mondo dal 1995 al 2010. I risultati dello studio, neanche a dirlo, si discostano parecchio dalla propaganda politica e dalle paventate invasioni strillate dai partiti xenofobi e nazionalisti europei.
While the results of the migration study aren't particularly groundbreaking, there are two interesting insights:
1. Adjusted for population growth, the global migration rate has stayed roughly the same since around 1995 (it was higher from 1990-1995).
2. It's not the poorest countries sending people to the richest countries, it-s countries in transition--still poor, but with some education and mobility--that are the highest migratory contributors.
"One of the conclusions they make in the paper is the idea as countries develop, they continue to send more migrants, and at some point they become migrant-receiving regions themselves," says Fernando Riosmena, a geographer from the University of Colorado, who did not contribute to this research, but is collaborating with one of the authors on a future paper.
A few other noteworthy results:
1. The largest regional migration is from Southeast Asia to the Middle East. This is largely driven by the huge, oil-driven construction booms happening on the Arabian Peninsula.
2. The biggest flow between individual countries is the steady stream from Mexico to the U.S. (In fact, the U.S. is the largest single migrant destination.)
3. There's a huge circulation of migrants among sub-Saharan African countries. This migration dwarfs the number leaving Africa, but the media pay more attention to the latter because of the austerity-driven immigration debates in Europe.
