The impact factor of PNAS (Proceedings of the National Academy of Sciences) is 9.4. This figure reflects the journal's standing based on its 2023 metrics.
Understanding PNAS and its Impact Factor
PNAS is a prestigious multidisciplinary scientific journal, recognized globally for publishing high-impact research across various fields of science, engineering, and medicine. The Impact Factor is a widely used metric that reflects the average number of citations received per paper published in that journal during a specified period. It's an important indicator of a journal's influence within the academic community.
Key Metrics for PNAS (2023)
To provide a comprehensive understanding of PNAS's standing, here are its key metrics:
| Metric | Value |
|---|---|
| Impact Factor | 9.4 |
| Ranking in Multidisciplinary Sciences | 13/134 |
| Impact Factor without Self-Cites | 9.2 |
| Five-Year Impact Factor | 10.8 |
These metrics offer different perspectives on the journal's citation performance and influence:
- Impact Factor (9.4): This standard metric calculates the average number of times articles published in the journal in the previous two years were cited in the current year. It provides a snapshot of the journal's recent citation performance.
- Ranking in Multidisciplinary Sciences (13/134): This indicates that PNAS is among the top journals in the broad category of Multidisciplinary Sciences, demonstrating its significant standing in a highly competitive field.
- Impact Factor without Self-Cites (9.2): This metric excludes citations where the citing journal is the same as the cited journal, offering a slightly adjusted view of influence by removing any potential self-citation bias.
- Five-Year Impact Factor (10.8): This metric considers citations to articles published over the past five years, providing a more stable and longer-term view of a journal's influence compared to the two-year impact factor.
These figures underscore PNAS's consistent role as a leading venue for scientific discourse and discovery. For more detailed information on PNAS article and journal metrics, you can visit the official PNAS website.
