Journal Citation Reports (JCR) 2026, reflecting 2025 data, is now available. JCR is a publisher-neutral database produced annually by Clarivate that provides a range of quantitative metrics—most notably the Journal Impact Factor (JIF). Integrated with Web of Science (WOS), JCR data is compiled from the WOS Core Collection, which includes the Science Citation Index Expanded, Social Sciences Citation Index, Arts and Humanities Citation Index, and Emerging Sources Citation Index. The United States continues to represent the plurality of represented authors at 25%, closely followed by mainland China at 23%.
The 2026 release includes 521 journals receiving a JIF (Excel) for the first time, with 58% of those journals from outside the United States and Western Europe, bringing the total number of journals tracked by JCR to 22,643. At the same time, a small number of journals were suppressed from the 2025 JCR Data for anomalous citation patterns, which could affect the journal’s Impact Factor.
