Between 1998 and 2002, Thomson ISI indexed 48,239 papers that listed at least one author address in Brazil. Of those papers, the
highest percentage appeared in journals categorized under the heading of agricultural sciences, followed by physics and space science. As
the relative-impact figures in the the right-hand column indicate, Brazil's citations-per-paper average was below the world mark in
all the fields shown (those fields in which Brazil contributed at least 100 papers to the ISI database over the last five years). The
nation's best relative-impact score was in psychology/psychiatry, where
Brazil's average of 2.64 citations per paper was just 16% below the world
average of 3.14 cites per paper. Brazil's performance was also comparatively strong in ecology/environmental sciences, mathematics, computer science, and engineering.
