Portugal’s world share of science and social-science papers over a recent five-year period, expressed as a percentage of papers in each of 21 fields in the Thomson Reuters database. Also, Portugal’s relative citation impact compared to the world average in each field, in percentage term.
|Field||% papers fr. Portugal||Impact vs. world|
|Plant & Animal Science||1.06||+6|
|Biology & Biochemistry||0.72||-22|
|Economics & Business||0.69||-38|
|Portugal's overall percent share, all fields: 0.67|

Between 2005 and 2009, Thomson Reuters indexed 34,797 papers that listed at least one author address in Portugal. Of those papers, the highest percentage appeared in journals classified under environment/ecology, followed by plant & animal science. As the right-hand column shows, Portugal’s impact (cites per paper) score in environment/ecology was just 3% below the world average in the field (4.59 cites per paper for Portugal, versus the world mark of 4.72). On the other hand, Portugal’s relative-impact scores were strong in other fields, notably space science, physics, and agricultural sciences. In engineering, the impact of research from Portugal-based authors happened to match the world figure exactly: 4.20 cites per paper.
