![]() | Immigration Economics Millions of people--nearly 3 percent of the world's population--no longer live in the country where they were born. Every day, migrants enter not only the United States but also developed countries without much of a history of immigration. Some of these nations have switched in a short span of time from being the source of immigrants to being a destination for them. International migration is today a central subject of research in modern labor economics, which seeks to put into perspective and explain this historic demographic transformation.
