"We’re the nation that just had six of our scientists and researchers win Nobel Prizes—and every one of them was an immigrant," U.S. President Barack Obama recently said after the Nobel Prize winners were announced.
The Internet was abuzz about it, and how could it not be?
The announcement couldn’t come at a better time. Not only are US Nobel laureates immigrants, but also the country has been identified as one of four where the world’s high-skilled immigrants are increasingly living, according to a new World Bank research article. The other three countries are the United Kingdom, Canada and Australia.
Titled Global Talent Flows, the research found that in 2010, there were about 28 million high‐skilled migrants residing in OECD countries (members of the Organization for Economic Cooperation and Development), an increase of nearly 130% since 1990. Only four OECD countries are the landing destination for nearly 70% of the 28 million migrants.
The study added that the United States alone has historically hosted close to half of all high‐skilled migrants to the OECD and one‐third of high‐skilled migrants worldwide. In 2010, the United States hosted 11.4 million skilled migrants, 41% of the OECD total.
The researchers explained that the forces behind the exceptional rise in the number of high-skilled migrants to OECD countries include the increased efforts to attract talent by policymakers who invest in human capital, the positive spillovers generated by skill agglomeration, the declines in transportation and communication costs, and the rising pursuit of foreign education by young people.
These factors, the researchers argued, also suggest that “high-skilled immigration is often controversial.” They added that for sending countries, the loss of high-skilled workers raises concerns, but the positive side of it is that those migrants “can create badly needed connections to global sources of knowledge, capital, and goods –and some will eventually return home with higher social and human capital levels.”
The research found that many origin countries have limited educational capacities and fiscal resources to train workers or to replace those that have emigrated. It added that countries experiencing particularly high emigration rates of high‐skilled workers to OECD destinations in 2010 tend to be small low‐income countries and island states.
“The reasons why people leave had to do with their living situation,” said World Bank economist Çaglar Ozden, one of the authors of the study. “If you improve and develop the country and improve the overall life of the educated people, they will stay.”
“Don’t push them,” he warned, adding that governments can do a lot of things to help bring back the talents. Dual citizenship, he said, is an example of “establishing links” with these talents to make them stay.

The research noted the “remarkable and unprecedented” role of women in this high-skilled migration surge, noting that ]the stock of high‐skilled female immigrants in OECD countries grew by 152% between 1990 and 2010, from 5.7 to 14.4 million. In 2010, female high-skilled migration outnumbered males.
According to the research, Africa and Asia, experienced the largest growth of high‐skilled female emigration, suggesting that gender inequalities and labor market challenges there had potential roles in becoming the push factors.
"The loss of highly educated women is a problem because mothers have the most impact on children," warned Ozden. “There would be long-term losses as educated mothers are educated children.”
The global competition for skills will continue to be fierce and will likely remain unequal, the research suggests, due to the volume of that migration to the four Anglo‐Saxon countries and the asymmetry in the concentration of leading universities, high‐tech firms and research centers.
The study concluded that skilled migration will continue to march forwarded. But while overall patterns remain similar, different forms of high skilled migration are likely to emerge and evolve.
