A new scientific study revealed today that 45% of migrants from all over the world returned to their country of origin between 1990 and 2015.
This new report was published today in the scientific journal Proceedings of the National Academy of Sciences of the United States of America, known by its initials PNAS and published weekly by the US National Academy of Sciences.
In the report, the two scientists at the University of Washington explain how new statistical methods have allowed them to make accurate estimates of migratory exchanges between countries.
Following this new method, they discovered that migration rates are higher and more stable than had been thought in the past and that, in fact, the fluctuation was between 1.1 and 1.3% between 1990 and 2015 .
In addition, since 1990, approximately 45% of migrants have returned to their places of origin, a much higher estimate than previously estimated.
The discovery could help governments around the world plan their migration policies.
