Immigration: An Economic Review

Immigration is a vital source of economic growth.

Wall decorations sometimes bear the message that home is where the heart is. But for millions across the globe, home is where the jobs are.

About 281 million people, or 3.6% of the world’s population, live outside of their country of birth. The number has increased over the past five decades.

Europe and Asia host the most international immigrants. At the country level, about half of all immigrants reside in just 10 countries. The United States leads the world with the highest number of settlers. Canada and Australia are also among the most sought after immigration destinations. About 30% of Australia’s population were born overseas, of which two-thirds are now residents. India is the leading source of the world’s expatriates, accounting for 18 million persons living abroad, followed by countries like Mexico, Russia and China.

Cross-border mobility collapsed during the pandemic but has since recovered across major advanced economies. Canada’s total population grew by a record 1.05 million in 2022, the largest spike since the post-World War II baby boom. Immigration accounted for 96% of that increase. Compared with the average annual increases in the 2010s, net immigration almost tripled last year to 3.3 million in the U.S. and to 670,000 in the U.K.
