How institutions are chosen and ordered
The directory lists 1436 universities, colleges and higher education institutions in 199 countries and territories. In countries with 200 or more higher education institutions recorded in OpenAlex it lists the top 25; everywhere else, the top 5.
Institutions are ordered by the total number of citations their research has received, as recorded in OpenAlex, the open catalogue of the world’s research, with data taken in October 2026. This is a transparent, research-based order: it favours large research institutions and does not measure teaching quality, student experience or graduate outcomes. University systems are left out in favour of their campuses, and faculties or institutes are left out when their parent university is already listed. Names, cities and websites come from OpenAlex and the Research Organization Registry (ROR).
Being listed is not an endorsement, and listings are not paid for. Spotted a mistake? Send a correction.
