How is CiteScore calculated?

The CiteScore is calculated based on the number of citations to documents (articles, reviews, conference papers, book chapters, and data papers) by a journal over four years, divided by the number of the same document types indexed in Scopus and published in those same four years.

For example, the 2021 CiteScore counts the citations received in 2018-2021 to articles, reviews, conference papers, book chapters, and data papers published in 2018-2021, and divides this by the number of these documents published in 2018-2021.

Peer-reviewed bibliometric literature, such as the Journal of Information Science, shows that a three-year window is long enough to capture the citation peak for most disciplines. However, CiteScore uses a four-year window. The four-year window was chosen to allow for a more recent year to be included in the equation, making the calculation more robust and stable.

How is Impact Factor calculated?

The Journal Impact Factor (JIF) is calculated from data indexed in the Web of Science Core Collection. It should be used with careful attention to the many factors that influence citation rates, such as the volume of publication and citations characteristics of the subject area and type of journal. The Journal Impact Factor can complement expert opinion and inform peer review.

The 2021 Impact Factor is calculated by adding the total number of citations in 2021 to items published in 2020 and 2019 divided by the number of citable items in 2019 and 2020.

How does CiteScore compare to Impact Factor?

While Impact Factor measures citations in one year to content published in the previous two years, CiteScore measures more broadly by counting citations to articles published in the previous four years.
