Each year the consulting and data analysis firm Clarivate compiles an annual list of researchers who have demonstrated significant and broad influence reflected in the publication of multiple papers frequently cited by their peers.

The 2021 list includes about 3,800 researchers in 21 scientific fields, and another 2,800 researchers identified as having exceptional performance across several fields. The citation analysis considered only papers in journals indexed in the Web of Science Core Collection during the period from 2010 to 2020. Highly cited papers are defined as those that rank in the top 1% by citations for field and publication year. The method, papers weighed against others in the same annual cohort, is intended to remove the citation advantage of older papers relative to recently published ones.
