Top 20 Nations

The nations dominating the lists of most cites and most papers begin with the US, with more than twice the total citations and total papers of any other nation. The European nations with a strong presence at CERN follow—the UK, Germany, Switzerland, Italy, France, and Spain highest among them.

Japan breaks the European string, at the #6 position in total papers and #4 in total cites, not surprisingly, with the University of Tokyo, Kyoto University, and the High Energy Accelerator Research Organization at KEK all showing up in the top 20 lists for institutions. Other non-European nations appearing in the top 20 include Russia, India, Canada, South Korea, China, Israel, and Taiwan.

Switzerland, the home base of CERN, also places high on the citations per paper list, at #3 with 24.75 cites per paper. The US (21.91 cites) and the UK (20.07 cites) also rank among the top 10 on this listing.

About The Nations



The resulting database contained 99 nations. Ranked by three separate measures: citations, papers, and citations per paper. Source dates: January 1, 2001-September 26, 2011. *Unless otherwise specified, all rankings have a >= 5 paper threshold for all measures.

Overall General Information


 
Top 20 Scientists, Institutions, Journals, & Nations

Citation tables allow us to map compelling trends:

  • Are there particular nations or institutions that might be expected to dominate research in the Topic area, and do the numbers bear out these expectations, or are there surprises?
  • Who are the leading scientists and where are they located?

While these tables cannot offer a complete picture, the number of trends and anomalies that can be spotlighted or connected across categories is striking. The tables often lead to renewed perspectives to further explore and validate.

What are Special Topics?



Special Topics, from ScienceWatch.com, is designed to complement Essential Science IndicatorsSM from Clarivate Analytics in providing citation analyses and commentary for selected scientific research areas that have experienced notable recent advances or are of special current interest.

Read about the overall methodology for Special Topics in the "What are Special Topics?" page.
