na = not applicable. NOTES: Internationally coauthored articles have at least one collaborating institution from the indicated country/economy and an institution from outside that country/economy. Article counts are from the set of journals covered by the Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Articles are classified by the year they entered the database, rather than their year of publication, and are assigned to a country/economy on the basis of the institutional address(es) listed in the article. Articles are credited on a whole-count basis (i.e., each collaborating country/economy is credited one count). Countries/economies are ranked by the percentage of their share of the United States’ international articles in 2012; countries/economies with less than 1% of the United States’ 2012 international articles are omitted.
