Telling a colleague that a CiteScore of 7.2 and a JIF of 4.2 are two different metrics for the same journal, not conflicting values.
Editorial commentary
Quick answer: The FASEB Journal’s Journal Impact Factor (JIF, Clarivate) is 4.2 in the 2024 metrics published by FASEB on the journal’s page (faseb.org, read 7 November 2026). The same page lists a CiteScore (Scopus) of 7.2 and a Journal Citation Indicator (Clarivate) of 0.87. These are three different measures, which is why sites quoting a single “impact factor” for the journal often disagree.
The FASEB Journal is the research journal of the Federation of American Societies for Experimental Biology (FASEB). FASEB describes its scope as spanning “all levels of biological organization, from molecular to population studies.” This entry explains which numbers are published for it, where they come from and how far they can be trusted as a signal.
What is The FASEB Journal impact factor?
The impact factor of The FASEB Journal (also searched as the FASEB impact factor, FASEB journal impact factor or impact factor of the FASEB journal) is the Journal Impact Factor that Clarivate assigns the title each year in the Journal Citation Reports. It is a property of the journal as a whole, recalculated every year, not a fixed attribute.
Current metrics for The FASEB Journal
| Metric | Value | Provider | What it measures |
|---|---|---|---|
| Journal Impact Factor | 4.2 | Clarivate | Citations in the data year to items from the previous two years, divided by citable items in those years |
| CiteScore | 7.2 | Scopus (Elsevier) | A separate citation ratio from the Scopus database, with its own window and document-type rules |
| Journal Citation Indicator | 0.87 | Clarivate | A Clarivate indicator listed alongside the JIF on the journal’s page |
Source: FASEB, “The FASEB Journal”, section “Journal metrics (2024)”, faseb.org/journals-and-news/the-faseb-journal, read 7 November 2026. Figures are the 2024 metrics as published there; a newer Journal Citation Reports release may show a different value, so name the data year whenever you cite one.
How is the journal impact factor calculated?
The standard two-year JIF divides the citations received in the data year by the journal’s articles and reviews from the two preceding years by the number of citable items it published in those two years. Because Clarivate’s own guidance states that the JIF is a journal-level measurement that should not be considered in isolation, it is normally read next to other indicators. See the FASEB overview for the society and its journals.
Why do websites give different numbers?
Third-party journal pages frequently show 4.2, 4.3, 7.2, 7.9 or other figures for the same title. The usual causes are that they are quoting different metrics (JIF versus CiteScore versus a Scimago indicator), different data years, or a five-year rather than two-year window. When a figure matters, take it from the publisher or society page that names the provider and year, or from Journal Citation Reports itself.
Is The FASEB Journal good?
No metric answers that alone. A JIF of 4.2 describes the average citation rate of the journal’s recent items; it says nothing about any one paper. Quality is better judged by fit with your subject, the journal’s peer-review and editorial practice, and how the paper itself is received. Clarivate states that the JIF is not for evaluating individual articles or researchers.
Is an impact factor of 7.5 good?
There is no threshold at which a number is “good” in the abstract. Impact factors differ widely between fields, so a value is meaningful only against other journals in the same Journal Citation Reports category. Quartile placement is category-specific and should be read in Journal Citation Reports rather than from a third-party summary.
What is the PNAS impact factor?
PNAS is a different journal with its own annual Clarivate value. Look it up in Journal Citation Reports or on the PNAS journal page, naming the data year, rather than relying on a figure quoted for another title.
Cautions on using the figure
- Cite the year and provider: “4.2 (2024 metrics, Clarivate JIF)”, not “an impact factor of about 4”.
- Do not use the journal figure to assess an individual article or author. The DORA declaration recommends against journal-based metrics as a surrogate for the quality of individual papers.
- Compare only within the same subject category and the same data year.
