How to interpret these rankings
These pages present scientists associated with Brazil in the 2026 single-year dataset. Country refers to the affiliation country recorded in the source data, not necessarily citizenship or nationality. Worldwide rank is taken from the dataset; country positions and institution totals are calculations made by this website.
Country position is based on the number of listed scientists, not an official assessment of national research quality. Institution counts use distinct nonblank affiliation names as recorded, so variants of the same institutional name may be counted separately. Historical changes describe representation in successive datasets and should not be interpreted as direct changes in research quality.
Frequently Asked Questions
Answers about Brazil based on the 2026 single-year ranking data.
1,510 researcher records are associated with Brazil in the 2026 single-year dataset. This is a count of listed researchers, not of all scientists working in the country.
Countries are ordered by their number of listed researcher records in the selected 2026 single-year dataset. The resulting position does not measure overall research quality, productivity, or national scientific capacity.
The Top 10 Institutions and Top 10 Disciplines charts show the most frequently represented institution names and disciplinary classifications among the listed researchers associated with Brazil. These are counts of researchers, not institutional or disciplinary quality scores.
The selected dataset contains 259 distinct nonblank institution names for Brazil. Differences in institutional naming may cause the same organization to appear under more than one name.
You can examine both views, but they reflect different citation-impact periods. A difference in counts or positions should not be interpreted as a direct change in research performance without considering the ranking methodology and data coverage.
