The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. [4] [5] In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023. [6]

[1] As of 2024, Journal Citation Reports gives the journal a 2023 impact factor of 10.6, ranking it fifth of 173 journal titles in the category "Food Science & Technology". [2]
The values for Nature journals lie well above the expected ca. 1:1 linear dependence because those journals contain a significant fraction of editorials. CiteScore was designed to compete with the two-year JCR impact factor, which is currently the most widely used journal metric. [7] [8] Their main differences are as follows: [9]
