What is CiteScore?

CiteScore is another metric for measuring journal impact using data from the Scopus database.The calculation of CiteScore for the current year is based on the number of citations received by a journal in that year for the documents published in the journal in the past three years, divided by the documents indexed in Scopus published in those three years.

CiteScore vs Journal Impact Factor


Major differences between CiteScore and Journal Impact Factor:

  • CiteScore calculation is based on Scopus data, while Impact Factor is based on Web of Science data.
  • CiteScore uses a 3-year window while Impact Factor adopts a 2-year window.
  • CiteScore includes all document types indexed by Scopus, include articles, reviews, letters, notes, editorials, conference papers, etc. while Impact Factor only includes "citable documents" which are articles and reviews.
