Harvard University in the US again placed first in the table of the Academic Ranking of World Universities (ARWU – also often referred to as the Shanghai Ranking).
But Sweden's performance was not too shabby, with the Karolinska Institute, Uppsala University and Stockholm University in the top 100s, and 13 universities in the top 1000s.
Sweden's medical school Karolinska Institute climbed to 38th place in the ranking, up from 44th last year.
It was followed by Uppsala in 62nd place and Stockholm as number 73, who both also improved their performance on last year.
Its Danish neighbours got the highest spot out of the Nordic countries, with University of Copenhagen in 26th place. But Sweden had the most universities listed compared to Denmark's and Norway's six each, Finland's eight and Iceland's one nod in the ranking.
The rest of the Swedish seats were Lund University (in a shared 101-150th spot), University of Gothenburg (151-200), KTH Royal Institute of Technology (201-300), Chalmers University of Technology (301-400), Linköping University (301-400), Swedish University of Agricultural Sciences (301-400), Stockholm School of Economics (401-500), Umeå University (401-500), Örebro University (801-900) and Luleå University of Technology (901-1000).
Among the six indicators used to rank the universities were the number of alumni and staff winning Nobel Prizes and Fields Medals, the number of highly cited researchers, and the number of articles cited in journals of nature and science
