NOTES: Region/country/economy ranked by share in 2001. Share based on publication counts from set of journals classified and covered by Science Citation Index (SCI) and Social Sciences Citation Index (SSCI) and on institutional address of article. Citations on fractional-count basis, i.e., for cited articles with collaborating institutions from more than one country/economy, each country/economy receives fractional credit on basis of proportion of its participating institutions. East Asia-4 consists of China, Singapore, South Korea, and Taiwan. China includes Hong Kong. Other OECD excludes United States, Japan, and South Korea. Detail may not add to total because of rounding.
