NOTES: Article counts from set of journals covered by Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Articles classified by year of publication and assigned to country on basis of institutional address(es) listed on article. Articles on fractional-count basis, i.e., for articles with collaborating institutions from multiple countries, each country receives fractional credit on basis of proportion of its participating institutions. See appendix table 5-23 for countries/economies included in EU and Asia-8. Percents may not add to 100% because of rounding.
