For this post, we have elaborated rankings of universities based on the output they have in each of the major scientific fields. Then we took the Top 100 in each field and saw them by countries. The result is the following table where each row represents a country and each cell shows how many institutions that country has within the Top 100 in the corresponding field. The rank is ordered by the average of institutions that countries have in Top 100. We have used Scopus as the data source, after a disambiguation process of institution names.
