National Rankings by Output in Sciences and Social Sciences, 1999-2008

February 2009

The data below were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1999 through October 2008, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Here our ranking in all fields of the sciences and social sciences is by papers produced. For articles with multiple authors from different nations, each nation receives full, not fractional, publication credit. Essential Science Indicators tabulated a total of 9,445,252 articles and reviews for the period indicated. The world percent figure is calculated for each nation based on that total. The percent shares of these top 20 nations sums to 102.8%, which reveals multinational coauthorship.

Essential Science Indicators surveys publication and citation data over a decade, with bimonthly updates. To contrast the world share figures for these nations for 1999-2008, Thomson Reuters’s consulted its National Science Indicators database, which covers the period 1981-2007, and checked the world share figures for these top 20 nations for 1989-1993. As the table above shows, the United States, Canada, and Russia have lost world share, comparing 1989-1993 with 1999-2008, whereas China, South Korea, Brazil, and Taiwan have increased their world shares of science and social science papers dramatically.
