This report maps the evolution of global higher education research from 1991 to 2024, examining how knowledge about higher education is produced, circulated and governed across global, regional and national scales. It traces who contributes to the field, where research is generated, the venues through which it is disseminated, the thematic directions it prioritises, and how collaboration networks have shifted during a period of profound transformation in the global higher education landscape. These patterns are situated within wider developments, including the massification of higher education, technological and demographic change, intensifying global interdependence, and shifts in national policy frameworks.
