Which Countries Have the Most Immigrants?
Immigrant rankings are simple on the surface but hide very different migration models. A country can rank highly because it is large, because it is rich, because it imports labour, or because it has made immigration part of how it grows.
Article details
The countries with the most immigrants include the United States with 50.6 million foreign-born residents, Germany with 15.8 million, Saudi Arabia with 13.5 million, Russia with 11.6 million, and the United Kingdom with 9.4 million. The list combines several models: a large destination country, labour-importing economies, regional mobility, refugee arrivals, and post-Soviet population patterns. The totals need that context.
A small group of countries holds a huge share of the world's immigrants
UN migrant-stock data shows strong concentration in a relatively short list of destination countries.
What this chart measures
International migrants living in the destination country (millions of people).
How to read it
Selected countries shown for comparison, not a full global ranking.
The world's largest immigrant destination in absolute terms.
A large European destination shaped by labor demand and regional movement.
A labor-importing state with heavy reliance on foreign workers.
A major destination within the post-Soviet migration system.
A long-run migration destination tied to labor, education, and history.
The top destination countries are large for different reasons, which is why the ranking needs explanation as much as attention.

Big countries have a head start
Large countries often rank highly because they can absorb more people. That helps explain why the United States sits far above the rest at 50.6 million. Scale alone is not enough, however: China, Indonesia, and Brazil are also large but do not appear near the top. Jobs, policy, safety, education, and established communities also pull people in.
- Absolute counts reward size first.
- A high ranking still needs a system behind it.
Labour demand creates a different kind of immigrant giant
Saudi Arabia (13.5 million foreign-born) did not become a top destination through classic immigration. It became one because its economy depends on large flows of foreign workers. Construction, domestic work, logistics, services. This is a distinct migration model: less about permanent settlement, more about economic demand. The workers come because the jobs exist. When the jobs shift, so does the population.
- A country can become a top destination through labour demand alone.
- The social meaning of the number changes when migration is mostly temporary.
Regional systems matter enormously
Germany (15.8 million) and Russia (11.6 million) remind us that migration often follows regional systems, not global ones. German industry pulled workers from Turkey, Poland, Romania, and Syria. Russia absorbed post-Soviet populations from Ukraine, Central Asia, and the Caucasus. These systems can be enormous even when they receive less attention in English-language media.
- A migration ranking often reflects a region, not just a country.
- Proximity and shared history still shape movement strongly.
Settler and service economies add yet another model
The United Kingdom (9.4 million), Canada, and Australia occupy another part of the spectrum. They combine labour demand with education, services, and longer-run immigration structures. Their immigrant populations include students, skilled workers, family-reunification arrivals, and refugees. The same ranking headline can hide very different national stories.
- Immigrant totals do not tell you whether the system is temporary, permanent, or mixed.
- The label “top destination” is far broader than it first appears.
The ranking is a map of how countries plug into the world
The countries with the most immigrants sit at major junctions of global life. They may offer jobs, safety, education, legal status, or several of these at once. The ranking maps where people keep arriving and why a country such as the United States reaches 50.6 million foreign-born residents.
