Which countries have the highest “highly-cited” researchers?
Countries with highly-cited researchers [2026 Update]
Achieving Highly Cited Researcher (HCR) status requires publishing multiple papers that rank in the top 1% by citations for their specific field and publication year. Clarivate identifies these influential scientists annually by analyzing a decade of citation data from the Web of Science and Essential Science Indicators (ESI).
The world of academic research is intensely competitive, with a constant drive to push the boundaries of knowledge. A key metric for assessing the influence and impact of individual scholars and, by extension, the strength of a nation's research output, is the number of citations their work receives. This leads to the compilation of various highly cited researchers lists, providing insights into the countries with highly-cited researchers and their contributions to the global scientific community.

Highly Cited Papers vs. Hot Papers
Distinguishing between ESI Highly Cited Papers and Hot Papers is critical for any academic aiming to join the Clarivate Highly Cited Researchers list. While Highly Cited Papers represent long-term authority—ranking in the top 1% of their field over a ten-year window—Hot Papers identify immediate research breakthroughs by ranking in the top 0.1% based on rapid citation "velocity" within the last two years. Together, these metrics provide a comprehensive view of a researcher’s impact, showing both foundational influence and current leadership in emerging scientific trends.
| Feature | ESI Highly Cited Papers | ESI Hot Papers |
|---|---|---|
| Citation Threshold | Top 1% of field and year | Top 0.1% of field and period |
| Publication Window | Past 10 years | Past 2 years |
| Data Tracking | Total cumulative citations | Citation velocity (last 2 months) |
| Strategic Value | Foundational long-term impact | Emerging research trends |
| HCR Eligibility | Primary metric for HCR list | Supporting signal of influence |
Highly cited researchers 2024-2025 by country
According to analyses, including data for the highly cited researchers 2024 by country (which often provides a strong indication for the upcoming highly cited researchers 2025 by country), the United States continues to lead the pack. Despite a gradual decline in its overall share since 2018, the U.S. remains home to the largest number of highly-cited researchers, demonstrating its enduring strength in research and innovation. Following closely, Mainland China has shown remarkable growth, rapidly increasing its share and solidifying its position as a major player in global research. The United Kingdom, Germany, and Australia consistently rank among the top countries with highly-cited researchers, showcasing robust academic ecosystems and significant contributions across various scientific fields. Other nations like Canada, the Netherlands, Hong Kong SAR, France, and Singapore also feature prominently in these global rankings, indicating their growing scientific influence. You can download the list of highly-cited researchers for the past 10 years from our website.
H-index ranking by country
These rankings of highly cited researchers by country are typically based on the frequency with which researchers' publications are cited by their peers in scholarly journals indexed by leading databases such as Web of Science and Scopus. These platforms help identify the world's most cited researchers by analyzing millions of research papers over a decade, pinpointing those whose work falls into the top 1% by citations in their respective fields. For individual scholars, checking their highly cited researchers Google Scholar profile can provide a personal h index by country and a snapshot of their citation metrics, reflecting their individual impact.
Beyond individual recognition, these compilations also contribute to highly cited scientific papers country rankings, offering a macro-level view of national research productivity and impact. For instance, statistics from Scimago Journal & Country Rank reveal overall citation counts and average citations per document for various countries, further reinforcing which nations are at the forefront of scientific discovery. The presence of a high number of highly-cited researchers within a country signifies a thriving research environment, often characterized by significant investment in R&D, strong academic institutions, and a collaborative research culture. While a single "most cited researcher" might capture headlines, it is the collective output of a nation's top scientific talent that truly drives its standing in the global research arena. Understanding these trends is crucial for policymakers, funding agencies, and academic institutions worldwide as they strive to foster environments conducive to groundbreaking research and international collaboration.
Highly-cited researchers (ranked based on countries)
We have previously mentioned the citation requirement for the EB1 green card/visa in this post, and you probably know the minimum citations needed for the EB1 visa. But, it could be interesting to know which countries have research papers with the highest citation count? According to the “Clarivate Highly-Cited Researchers 2025”, the top 10 home countries of the highly-cited researchers are:
1- United States
2- Mainland China
3- United Kingdom
4- Germany
5- Australia
6- Canada
7- The Netherlands
8- Hong Kong SAR
9- France
10- Singapore
The table below shows the exact numbers of researchers identified as “highly-cited” in each country. It is worth mentioning that the US, with more than 2500 highly-cited researchers, stays in first place, and China is in second place. The numbers for these two countries compared to the other ones are significantly different, so probably the top countries in the list know how to increase citation score. Clarivate identified 6,636 individual researchers from institutions in 59 countries/regions who fulfill the characteristics of being highly cited in their fields of research.

The Clarivate highly cited researchers 2025 report highlights a growing concentration of top talent in the United States and China, while also implementing stricter integrity filters to exclude anomalous citation patterns.
What are the ISI highly cited researchers?
ISI highly cited researchers refers to the historical and foundational database of top-tier scientists originally established by the Institute for Scientific Information (ISI). Founded by Eugene Garfield, the ISI highly cited researchers metric was the first to standardize the identification of "elite" scientists based on citation frequency. Today, while the Institute is part of Clarivate, the legacy of the ISI highly cited researchers program continues to underpin the modern methodology used to track global research excellence and impact.
Who are the most highly cited researchers globally?
The most highly cited researchers are typically found in high-impact fields such as Clinical Medicine, Biology, and Chemistry, often affiliated with top-tier institutions like Harvard or the Chinese Academy of Sciences. These most highly cited researchers are the primary drivers of scientific breakthroughs, with their work forming the foundation for future studies. Reaching the status of the most highly cited researchers requires not only high-quality output but also a proactive strategy to ensure global visibility in major academic databases.
How do Elsevier highly cited researchers differ from other lists?
The Elsevier highly cited researchers data, often associated with the Stanford University database, provides a broader overview by ranking the top 2% of scientists worldwide using Scopus metrics. While Clarivate focuses on the top 1% within the Web of Science, the Elsevier highly cited researchers list offers standardized information on career-long impact and single-year performance across 174 sub-fields. Both metrics are essential, but elsevier highly cited researchers are often cited as a more comprehensive look at science-wide author databases.
How can I join the ranks of highly-cited researchers in my field?
Becoming one of the highly-cited researchers requires a combination of high-impact research, international collaboration, and strategic academic SEO. To move closer to being one of the most highly cited researchers, you must ensure your work is published in journals indexed by ISI, Clarivate, or Elsevier.
