Methodology of the Leiden rankings

The Leiden rankings are based on bibliometric indicators linked to scientific publications. The identification of these is supported by the bibliographic database of the Web of Science, Core Collection produced by Clarivate Analytics and on the enhancements by scientists of the Centre for Science and Technology Studies of the University of Leiden in the Netherlands. For this year’s rankings, the articles and reviews are based on publications for the period from 2017 to 2020 in international magazines grounded in subject matters. By major themes, the indicators are broken down based on the number of citations amongst 1%, 5%, 10% or 50% of the articles the most cited worldwide.
