Global Overview of American Expats by Country
The number of American expats by country is tracked through U.S. government registrations, tax filings, and census surveys. The most recent comprehensive data from the U.S. Department of State and the Internal Revenue Service shows that millions of U.S. citizens and green card holders are living abroad, with the highest concentrations in a small group of countries. The State Department estimates that around 9 million U.S. citizens are living overseas, and the IRS consistently reports millions of tax returns filed from foreign addresses each year. This global footprint is shaped by work opportunities, retirement choices, and family reunification, with a few countries absorbing a large share of the total American expat population.

When analysts rank the number of American expats by country, the list is led by a handful of nations that offer strong job markets, favorable tax treaties, or established expat communities. The top destinations include countries in Western Europe, North America, East Asia, and the Middle East, where multinational corporations, technology firms, and financial institutions hire U.S. talent. The IRS Publication 54 and related guidance highlight the importance of understanding foreign earned income exclusions and reporting requirements, which influence where Americans choose to settle. Companies such as Forbes Advisor regularly publish rankings of the best countries for American expats based on cost of living, safety, and visa ease. These rankings align with the countries that consistently report the largest clusters of U.S. citizens on tax and embassy records.
