On the list of nations that dominate in terms of citations and papers published, it's not surprising that the US, with Brookhaven, Fermilab, and a strong presence at CERN, leads the list of most cites and most papers, while the European nations with the biggest contributions to CERN follow along—Germany, France, Switzerland, and Italy. Russia, Japan, and China also make the top 10.

The surprise comes in the top 20 list for citations per paper. Here the major players virtually vanish—the US is nowhere to be found—and the top six begins with Hungary and then goes onto Israel, Croatia, Denmark, Romania, and Taiwan. These countries are also partners in the various research collaborations, but due to their smaller volume of papers, the cites-per-paper figures are higher than partner nations with larger paper volumes.

About The Nations

The resulting database contained 82 nations. Ranked by three separate measures: citations, papers, and citations per paper. Source dates: January 1, 2000-June 30, 2010 (third bimonthly period 2010). *Unless otherwise specified, all rankings have a >= 5 paper threshold for all measures.

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 Thomson Reuters in providing citation analyses and commentary for selected scientific research areas that have experienced notable recent advances or are of special current interest.
