Global migration has lifted millions out of poverty and boosted economic growth, a new World Bank report finds. But destination countries risk losing out in the global competition for talent and leaving large gaps in their labour markets. The report argues that migration will be a fundamental feature of the world for the foreseeable future due to continued income and opportunity gaps, differences in demographic profiles, and the rising aspirations of the world’s poor and vulnerable.
Large and persistent differences in wages across the globe are the main drivers of economic migration from low- to high-income countries, according to Moving for Prosperity: Global Migration and Labor Markets. Migrants often triple their wages after moving to a new country, helping millions of migrants and their relatives at home escape poverty. Destination countries often benefit as migrants fill critical roles, from advancing the technological frontier in Silicon Valley to building skyscrapers in the Middle East.
Despite the lure of higher wages, rates of migrants as a share of the global population have remained mostly unchanged for more than five decades, even as global trade and investment flows have expanded exponentially during this time. Between 1960 and 2015, the share of migrants in the global population has fluctuated narrowly between 2.5 and 3.5 percent, with national borders, distance, culture, and language acting as strong deterrents.
“The number of international migrants continues to remain fairly modest, but migrants often arrive in waves and cluster around the same locations and types of jobs,” said Shantayanan Devarajan, World Bank Senior Director for Development Economics and acting Chief Economist. “Better policies can manage these transitions in a way that guarantees long-term benefits for both citizens and migrants.”

Highlights of key findings from the report include:
• Migration flows are highly concentrated by location and occupation. Currently, the top 10 destination countries account for 60 percent of around 250 million international migrants in the world.
• Surprisingly, concentration levels increase with skill levels. The United States, the United Kingdom, Canada and Australia are home to almost two-thirds of migrants with tertiary education. At the very peak of talent, an astonishing 85 percent of all immigrant Nobel Science Prize winners are in the United States.
• Education levels of women are rapidly increasing, especially in developing countries, but opportunities for career growth remain limited. As a result, college educated women from low and middle-income countries are the fastest growing group among immigrants to high-income countries.
