The data above were extracted from the Essential Science Indicators database of Thomson Reuters. The database, currently covering the period January 1999 to December 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.

Germany ranks third in output, third in number of citations received, and 11th in citations per paper (among nations publishing 50,000 or more papers during the period) across the science and social science fields surveyed in Essential Science Indicators. The table above ranks fields for Germany by relative citation impact – that is, citations per paper for Germany in a field compared with the global average citations-per-paper score in the same field. Germany’s percentage above or below the world average is presented in the column at the far right. Only in the fields of psychiatry/psychology and economics/business did Germany fail to achieve the world average in citation impact.
