Clarivate Identifies the One in 1,000 Citation Elite with Annual Highly Cited Researchers ListMainland China has nearly doubled its share of Highly Cited Researchers in four years | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
London, United Kingdom Clarivate Plc (NYSE:CLVT), a global leader in providing trusted information and insights to accelerate the pace of innovation, unveiled its 2021 list of Highly Cited Researchers™ today. The methodology that determines the “who’s who” of influential researchers draws on the data and analysis performed by bibliometric experts and data scientists at the Institute for Scientific Information™ at Clarivate.
The annual list identifies some 6,600 researchers from across the globe who demonstrated significant influence in their chosen field or fields through the publication of multiple highly cited papers during the last decade. The Highly Cited Researchers’ names are drawn from the publications that rank in the top 1% by citations for field and publication year in the Web of Science™ citation index, and the list identifies the research institutions and countries where they are based.
The key findings for 2021 show:
Naturally, Mainland China’s gain means losses elsewhere. There is a 1.8% loss in Highly Cited Researchers for the United States since last year and 3.6% since 2018. This contrasts with an increase of 6.3% for Mainland China since 2018. The United Kingdom exhibits a decline of .5% since last year and 1.5% since 2018. Germany has lost .9% share since 2018.
David Pendlebury, Senior Citation Analyst at the Institute for Scientific Information, said, “The headline story is one of sizeable gains for Mainland China and a decline for the United States, particularly when you look at the trends over the last four years, which reflect a transformational rebalancing of scientific and scholarly contributions at the top level through the globalization of the research enterprise.”
Nobel Prize recipients and researchers of Nobel quality This year’s list includes 24 Nobel laureates, including five announced this year: David Julius, University of California San Francisco, San Francisco, CA, United States (Physiology or Medicine); Ardem Patapoutian, Scripps Research, La Jolla, CA, United States (Physiology or Medicine); David W. C. MacMillan, Princeton University, Princeton, NJ, United States (Chemistry); David Card, University of California Berkeley, Berkeley, CA, United States (Economics); and, Guido Imbens, Stanford University, Stanford, CA, United States (Economics). Also included are 77 Citation Laureates™: individuals recognized by Clarivate, through citation analysis, as ‘of Nobel class’ and potential Nobel Prize recipients.
Exceptional broad performance Of the researchers named as Highly Cited in the 21 Essential Science Indicators (ESI)™ fields, 23 researchers showed exceptionally broad performance, recognized for being highly cited in three or more fields. They are a truly global group – in North America, Europe, Asia and the Middle East. Professor Rob Knight from the University of San Diego California was alone in being named for four ESI fields (Biology and Biochemistry; Environment/Ecology; Microbiology; Molecular Biology and Genetics).

Joel Haspel, SVP Strategy, Science at Clarivate said, “This year’s data reflect a decade’s worth of research publications from the global scientific community. As well as documenting the ‘Eureka!’ moments, our data tell the story of late nights spent filling in grant applications, poring over results in the lab, the unsung work of peer reviewing contemporaries’ manuscripts, and the many small failures that ultimately lead to bigger successes and accelerating innovation. Our analysts have found continued growth in the highly cited, high-impact research from Mainland China, but the United States remains the scientific powerhouse of the world, and U.S. institutions represent five of the top ten, with Harvard University at the very top of the leader board.”

Notes to editors
Methodology
The sharp decline of .7% for Switzerland since 2018 is anomalous and reflects a change in our methodology: Papers with more than 30 institutional addresses were removed from our analysis in past years, but this year we eliminated papers with more than 30 authors or group authorship. The change, which we judged an improvement in reasonably crediting individual authors – the previous use of institutional addresses was a heuristic – happened to impact Switzerland heavily and especially researchers at the Swiss Institute of Bioinformatics, which produces a significant number of highly cited papers with many authors but few institutional addresses.
