PNAS Impact Factor

Here in this post, apart from PNAS Impact Factor, I have tried to compile all the necessary information a research scholar would seek before publishing an article in the journal.

About PNAS Journal

Proceedings of the National Academy of Sciences of the United States of America (PNAS) is a peer-reviewed multidisciplinary scientific journal.

It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters.

PNAS 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.

For example,

  • 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

PNAS Impact Factor (2017-2022)

  • PNAS Impact Factor 2017 – 9.504
  • PNAS Impact Factor 2018 – 9.580
  • PNAS Impact Factor 2019 – 9.412
  • PNAS Impact Factor 2020 – 11.205
  • PNAS Impact Factor 2021 – 12.777 (updated in June 2022)

PNAS H-index

The h index is a metric for evaluating the cumulative impact of an author’s scholarly output and performance; measures quantity with quality by comparing publications to citations.

Journal H Index Logo
