Finland's world share of science and social-science papers over the last five years, expressed as a percentage of papers in each of 22 fields in the   Thomson Reuters database. Also, Finland's relative citation impact compared to the world average in each field, in percentage terms.

Between 2003 and 2007, Thomson Reuters indexed 40,106 papers that listed at least one author address in Finland. Of those papers, the highest percentage appeared in journals classified under the heading of ecology/environmental sciences, followed by space science and neurosciences & behavior. As the right-hand column indicates, the citations-per-paper average (or impact) for ecology papers from Finland during the five-year period surpassed the world average by 33% (5.38 cites per paper for Finland, versus the world baseline of 4.06 cites per paper). Relative-impact scores for Finland were also notably strong in agricultural sciences (50% above the world average), physics (42% above), and clinical medicine (+39%).
