The data above were extracted from the Essential Science Indicators database of Thomson Reuters. The data­base, currently covering the period January 1999 through August 2009, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based

on the journals in which they were published and the journal-to-category field-definition scheme used by Thomson Reuters. Both articles tabulated and citation counts to those articles are for the period indicated.

Singapore ranks 31st in output, 30th in citations received and 22nd in citations per paper (among nations publishing 50,000 or more papers during the period) across the science and social science fields surveyed.

The table above ranks fields for Singapore by relative citation impact, that is, citations per paper for Singapore in a field compared with the world’s citations per paper score in the same field. Singapore’s percentage above or below the world average is presented in the column at far right. Exceptional areas of strength for Singapore, according to this measure, are agricultural sciences, materials science and mathematics.
