Scientific articles and collaborations between states : Revista Pesquisa Fapesp

Published scientific articles¹ that include authors from more than one institution or more than one geographic region generally achieve greater visibility than others, as shown by the number of times they are cited in other scientific papers
In Brazil specifically, the intensity of interstate collaborations—meaning the percentage of papers published by each state involving authors from another state—is another interesting factor
The chart below shows the following information across two three-year periods (2010–2012 and 2022–2024) for each state: number of articles published (horizontal axis, logarithmic scale); percentage published in collaboration with at least one other state (vertical axis); and the ratio between scientific output and population aged 25 to 64 (size of circle)

The number of published articles increased significantly in all states, especially in Amapá, Acre, Alagoas, and Rondônia
In most states, the ratio of published articles to population size exceeded 50 articles per every 100,000 inhabitants
For most states, the percentage of articles published through collaborations increased. In the most recent three-year period, almost all states reached their highest value in this indicator, which exceeded the 2010–2012 figure by an average of 11 percentage points
In both three-year periods, there was an inverse relationship between the total number of published articles and the percentage published through collaborations; states that published more papers tended to have lower collaboration rates than those that published fewer
