Publications Output: U.S. Trends and International Comparisons | NSF - National Science Foundation

"Key takeaways:

• The United States remains a highly influential nation in science and engineering (S&E) research, as measured by the volume of peer-reviewed scholarly publications and the rate of citations to those publications.
• In 2022, China remained the largest producer of publications, followed by the United States, then by India. China’s top scientific field in terms of number of articles produced was engineering (25% of all publications), whereas the top field in the United States was health sciences (37%), and India’s top field was computer and information sciences (21%).
• Analysis of funding acknowledgments shows that from 2018 to 2022, the scientific fields most frequently acknowledging federal funding are chemistry, biological and biomedical sciences, astronomy and astrophysics, and physics.
• The United States, the European Union (EU-27), and China currently produce a high number of highly cited articles, relative to their overall production.
• Open access (OA) has become an increasingly important feature of the publication landscape, in terms of output and impact, as shown by the growth of fully OA articles.
• International collaborations with U.S. authors of S&E publications have increased over the last 15 years, and China is the most frequent U.S. partner.
• International collaboration in the fast-growing field of artificial intelligence helps show an important research network and the most important collaborations in terms of absolute and relative size."
