Understanding the Impact Factor: What It Is and How It Is Calculated
Definition of Impact Factor
The impact factor (IF) is a quantitative measure that indicates the average number of citations received per paper published in a journal during a specific period, typically two years. It is widely used as an indicator of a journal’s relative importance within its field.
Calculation of Impact Factor
The impact factor for a given year is calculated as follows:
- Identify the number of citations received in the current year to articles published in the journal during the previous two years.
- Determine the total number of articles published in the journal during those two years.
- Divide the total citations by the total number of articles to obtain the impact factor.
Formula:
\[ \text{Impact Factor} = \frac{\text{Citations in Year N to articles published in Years N-1 and N-2}}{\text{Number of articles published in Years N-1 and N-2}} \]
This metric is published annually by Clarivate Analytics through the Journal Citation Reports (JCR).
