About Clarivate JCR-based Journal Impact Factors 2025

The Journal Impact Factor is a journal-level bibliometric indicator published by Clarivate in Journal Citation Reports (JCR). It is often abbreviated as JIF; JIF is not a separate impact factor, but simply the abbreviation for Journal Impact Factor.

The 2025 Journal Impact Factor provides a journal-level indication of citation activity. It should be interpreted within the journal’s subject area and together with other information, rather than used as a stand-alone judgment of research quality.

On this website, you can explore Journal Impact Factor records presented as Clarivate JCR-based data, together with the five-year Impact Factor, JCR quartile (Q1–Q4), JCR category rank, publisher details and journal identifiers. Verify important submission or evaluation decisions in the official Clarivate Journal Citation Reports.
