International & Mobile Students
The number of internationally mobile tertiary students has more than tripled since 2000, reaching nearly 6.9 million in 2022. A handful of English-speaking destinations host most of them, while China and India dominate the supply of students. These charts map the global flows, hosts and origins of study abroad.
Key International Student Insights
More than tripled since 2000
Internationally mobile tertiary students grew from 2.1 million in 2000 to nearly 6.9 million in 2022, one of the fastest-rising trends in global higher education.
English-speaking hosts dominate
The United States (833,000), United Kingdom (601,000), Australia (378,000) and Germany (376,000) lead host countries; the UK, US, Canada and Australia together take more than 70% of OECD international students.
China and India supply the flows
China sent over 1.05 million students abroad in 2022 and India 622,000, together about a quarter of all mobile students worldwide.
Still a small share of enrolment
Despite rapid growth, internationally mobile students were just 2.7% of global tertiary enrolment in 2022, though roughly one in five higher-education students in Oceania has crossed a border.
Internationally Mobile Students, 2000-2022
Global count of tertiary students studying outside their country of citizenship, showing the more-than-tripling since the turn of the century.
Key Finding: The total rose from 2.1 million in 2000 to nearly 6.9 million in 2022.
Top Host Countries (2021)
Number of internationally mobile students hosted by the leading destination countries, in thousands.
Key Finding: The United States hosts the most at 833,000, ahead of the UK (601,000) and Australia (378,000).
Top Countries of Origin (2022)
Number of students from each country studying abroad, in thousands, for the largest sending countries.
Key Finding: China (1.05 million) and India (622,000) send by far the most students abroad.
Share of OECD International Students by Destination
How international students enrolled across OECD countries are distributed among the leading host nations.
Key Finding: The UK (22%), US (21%) and Canada (17%) account for the majority of OECD international enrolment.
International Share of Global Tertiary Enrolment
Internationally mobile students as a percentage of all students enrolled in tertiary education worldwide.
Key Finding: Mobile students were 2.7% of global tertiary enrolment in 2022, up from 2.1% in 2000.
Understanding International Student Data
What counts as an internationally mobile student
UNESCO UIS defines internationally mobile students as those who have crossed a national border to study and are enrolled outside their country of origin. This is narrower than the broader category of foreign students, which counts non-citizens regardless of where they were educated and can include long-term residents who never migrated to study. Country totals can differ depending on which definition a source uses.
Host versus origin
Mobility data has two sides. Host (destination) figures count students received by a country, while origin (sending) figures count where students come from. The two do not sum to the same totals across sources because not every country reports both inbound and outbound flows, and a student counted as outbound by their home country may not appear in a destination that does not report international enrolment.
Data lags and revisions
International enrolment statistics are typically released two to three years after the reference year, and figures are frequently revised. The most complete global UNESCO UIS totals here are for 2021 (about 6.4 million) and 2022 (nearly 6.9 million); commercial trackers such as IIE Open Doors and Project Atlas report more recent estimates around 6.4-7.3 million depending on coverage and counting rules.
Caveats
Different agencies use different reference periods, academic-year conventions and inclusion rules (for example, whether short-term exchange or distance students are counted). Some major hosts, including the Russian Federation, have incomplete recent reporting. Percentages and ranks should be read as indicative rather than exact, and cross-source comparisons should match definitions and years carefully.
