Countries with the Highest (and Lowest) Proportion of Immigrants
For people living in cosmopolitan urban centers, it’s easy to overestimate the prevalence of immigrants around the world.
The median proportion of foreign-born people in all countries is just over 5%. In countries with a population greater than one million, only four are majority foreign-born, and only eight surpass the one-third mark.
Countries with the Highest Proportion of Immigrants
The United Arab Emirates comes out on top for the highest proportion of immigrants in its population. Impressively, the small Middle Eastern nation ranks sixth in the world for total immigrant population (8.7 million people).
Other countries on the Arabian Peninsula also rank at the top of this list. In Qatar, current host of the 2022 World Cup, 3-in-4 people are immigrants. The high proportion of foreign workers in the country also results in an extreme demographic skew—approximately 75% of the population of Qatar is male.
The one extreme outlier in the region is war-torn Yemen, where only 1.3% of the population are immigrants.
Outside the Middle East, Singapore (43%) takes top spot, followed by Australia (30%).
Spotlight on U.S. Immigration
Although the United States is outside the top 20, it still has by far the most immigrants of any other country (50 million vs. 16 million in second-place Germany).
About 15% of people in the U.S. are immigrants—numbers which are comparable to the historic high in the late 19th century. The proportion of foreign-born people in the country has been on the rise since the 1970s, and is projected to continue rising in coming decades. Around 2030, immigration is expected to surpass natural increases as a driver of population growth.
