iScience Impact Factor
Impact Factor (IF) or often called journal impact factor (JIF) is an index provided by an analytics company named Clarivate. The impact factor is calculated by dividing the number of times the articles are cited in the last two years by the total number of publications in those two years.
- Total Citations in 2020 and 2021 = 500
- Total Number of Publications in 2020 and 2021 = 100
- Impact Factor of the Journal in 2022 = 500/100 = 5
iScience Impact Factor (2017-2025)
The trajectory of iScience‘s Impact Factor since its inclusion in the JCR tells a compelling story of a new journal’s rapid ascent followed by a period of stabilization and market correction. The historical data shows a clear pattern of initial growth, a peak, and a subsequent moderation
- iScience Impact Factor 2017 –
- iScience Impact Factor 2018 – 4.39
- iScience Impact Factor 2019 – 5.08
- iScience Impact Factor 2020 – 5.74
- iScience Impact Factor 2021 – 6.107 (Peak)
- iScience Impact Factor 2022 – 5.8
- iScience Impact Factor 2023 – 4.6
- iScience Impact Factor 2024 – 4.1 (updated June 2025)
iScience’s Impact Factor dip since 2021 reflects post-COVID citation “normalization” and Cell Press’s expanding portfolio. With new specialized journals attracting high-impact papers, fewer land in iScience. The trend signals market dynamics, not declining quality.
