The data above were extracted from the Essential Science Indicators database of Thomson Reuters. The database, currently covering the period January 1999 to February 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 Thomson Reuters’ journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated.

Scotland ranks 23rd in output, 15th in citations received and fifth in citations per paper (following Switzerland, the US, Denmark and the Netherlands, respectively) across the science and social science fields surveyed in Essential Science Indicators. The table above ranks fields for Scotland by relative citation impact – that is, citations per paper for Scotland in a field compared with the world’s average citations per paper score in the same field. Scotland’s percentage above or below the world average is presented in the column at the far right. Only in economics and business did Scotland’s performance, by this measure, fall below the world average. Outstanding areas for Scotland include agricultural sciences, pharmacology and toxicology, space sciences and plant and animal sciences – all more than 50 per cent above the world average in terms of relative citation impact.
