Background on SJR

The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus database (Elsevier).

The SJR was developed by SCImago from the Google PageRank algorithm.

SCImago is a research group dedicated to information analysis, representation and retrieval by means of visualisation techniques.

What is ScImago Journal Ranking (SJR)?

Developed by Professor Félix de Moya, Research Professor at Consejo Superior de Investigaciones Científicas, SCImago Journal Rank (SJR) is a prestige metric based on the idea that ‘all citations are not created equal’. With SJR, the subject field, quality and reputation of the journal has a direct effect on the value of a citation.


  • Is weighted by the prestige of the journal, thereby ‘leveling the playing field’ among journals
  • Eliminates manipulation: raise the SJR ranking by being published in more reputable journals
  • ‘Shares’ a journal’s prestige equally over the total number of citations in that journal
  • Normalizes for differences in citation behavior between subject fields

SJR was developed using Elsevier (Scopus) citation data. (open access)
