Between 2005 and 2009, Thomson Reuters indexed 40,914 papers that listed at least one author address in Mexico. Of those papers, the highest percentage appeared in journals classified under the main heading of space science, followed closely by plant & animal science. As the right-hand column shows, the impact (or cites per paper) score of space science reports featuring Mexico-based authors was at 88% of the world average for the five-year period (or just 12% below: 6.74 cites per paper for Mexico versus the world mark of 7.69 cites). The country’s impact scores were also comparatively strong in physics, environment/ecology, and clinical medicine.
