What is an Impact Factor?
An impact factor is a metric used to evaluate the influence of a journal within its field. It is calculated by dividing the number of citations a journal receives in a given year by the total number of articles it published in the previous two years. The impact factor is a key indicator of a journal's prestige and relevance in the academic community.
Why is the Impact Factor Important?
The impact factor is crucial for several reasons:
- It helps researchers identify high-quality journals for publication.
- It influences the visibility and credibility of published research.
- It plays a role in academic promotions and grant applications.
NEJM Impact Factor: Historical Overview
The NEJM's impact factor has consistently ranked among the highest in the medical field. Over the years, it has maintained its position as a leader in publishing impactful research. Below is a table summarizing the NEJM's impact factor over the past decade:
| Year | Impact Factor |
|---|---|
| 2013 | 54.420 |
| 2015 | 59.558 |
| 2017 | 72.406 |
| 2019 | 74.699 |
| 2021 | 91.245 |
How is the Impact Factor Calculated?
The calculation of a journal's impact factor involves a straightforward formula:

Impact Factor = (Citations in Year X to Articles Published in Years X-1 and X-2) / (Total Articles Published in Years X-1 and X-2)
For example, if NEJM received 10,000 citations in 2023 for articles published in 2021 and 2022, and it published 500 articles in those two years, its impact factor would be:
10,000 / 500 = 20.0
Limitations of the Impact Factor
While the impact factor is a useful metric, it has limitations:
- It does not account for the quality of individual articles.
- It can be influenced by self-citations or citation stacking.
- It may not reflect the journal's broader societal impact.
