About Journal Impact
Impact Factor - What is it?; Why use it?
The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to measure the importance or rank of a journal by calculating the times its articles are cited.
How Impact Factor is Calculated?
The calculation is based on a two-year period and involves dividing the number of times articles were cited by the number of articles that are citable.
Calculation of 2010 IF of a journal:

Journal Citation Reports
Journal Citation Reports provides ranking for journals in the areas of science, technology, and social sciences. For every journal covered, the following information is collected or calculated: Citation and article counts, Impact factor, Immediacy index, Cited half-life, citing half-life, Source data listing, Citing journal listing, Cited journal listing, Subject categories, Publisher information.
- Limited to the citation data of Journals indexed in Web of Science
- Process to determine journals included in the tool
- Indexes over 12,000 journals in arts, humanities, sciences, and social sciences
You can enter a journal title in the Search box under "Go to Journal Profile". Because impact factors mean little on their own, it's best to view the journal you are interested in comparison to the other journals in the same category. To determine the impact factor for a particular journal, select a JCR edition (Science and/ or Social Science), year, and Categories, found on the left of the screen. Click Submit . Scroll the list to find the journal you are interested in. The list can be resorted by Journal time, Cites, Impact Factor, and Eigenfactor.
Scopus provides three journal metrics - CiteScore, SJR (SCImago Journal Rank) and SNIP (Source Normalized Impact per Paper). Once you are in Scopus, click on "Sources" at the top to access the journal impact data. See below for more on SJR and SNIP

SCImago Journal Rank (SJR)
“The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.).” Scopus contains more than 15,000 journals from over 4,000 international publishers as well as over 1000 open access journals. SCImago's "evaluation of scholarly journals is to assign weights to bibliographic citations based on the importance of the journals that issued them, so that citations issued by more important journals will be more valuable than those issued by less important ones." ( SJR indicator )
SNIP (Source Normalized Impact per Paper)
Source Normalized Impact per Paper (SNIP) measures contextual citation impact by weighting citations based on the total number of citations in a subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa. Unlike the well-known journal impact factor, SNIP corrects for differences in citation practices between scientific fields, thereby allowing for more accurate between-field comparisons of citation impact. CWTS Journal Indicators also provides stability intervals that indicate the reliability of the SNIP value of a journal. SNIP was created by Professor Henk F. Moed at Centre for Science and Technology Studies (CWTS), University of L
CWTS Journal Indicators currently provides four indicators:
- P. The number of publications of a source in the past three years.
- IPP. The impact per publication, calculated as the number of citations given in the present year to publications in the past three years divided by the total number of publications in the past three years. IPP is fairly similar to the well-known journal impact factor. Like the journal impact factor, IPP does not correct for differences in citation practices between scientific fields. IPP was previously known as RIP (raw impact per publication).
- SNIP. The source normalized impact per publication, calculated as the number of citations given in the present year to publications in the past three years divided by the total number of publications in the past three years. The difference with IPP is that in the case of SNIP citations are normalized in order to correct for differences in citation practices between scientific fields. Essentially, the longer the reference list of a citing publication, the lower the value of a citation originating from that publication. A detailed explanation is offered in our scientific paper.
- % self cit. The percentage of self citations of a source, calculated as the percentage of all citations given in the present year to publications in the past three years that originate from the source itself.

Each journal covered in the Journal Citation Reports has a Journal Profile page providing a comprehensive overview of related information and Key Indicators , allowing users to see multiple years of data in a glance. Information related to the journal's publisher, location, and publication frequency, and other criteria relevant are presented at the top of the page beneath the title.
The Journal Profile page also provides access to detailed information about the journal, data, metrics and content underlying the journal’s listing in the JCR.
The profile provides the following information:
Select the year (the most recent, a previous year, or All Years to all available data summarized).
Journal Information Journal Impact Factor (JIF) trend and calculation (with and without self-citations) Journal Impact Factor contributing items Journal Citation Indicator (JCI) trend Total Citations Citation Distribution Open access (OA) items and citations Rank by Journal Impact Factor (JIF) Rank by Journal Citation Indicator (JCI) Content metrics (source data and contributions by organizations and location) Additional metrics (Eigenfactor Score, Normalized Eigenfactor, Article Influence Score, and Immediacy Index)
The Journal information section contains:
Basic bibliographic information about the journal, including publisher, ISSN and e-ISSN (where available), open access status, language, frequency of publication, and Web of Science categorization.
A link to the current and previous years, plus an All Years summary.
In the top right of the journal profile page, you can either click on the heart icon to Favorite a journal or on the download icon to Export to PDF.
Selecting All Years for the journal profile displays yearly breakdown of key JCR metrics including the following indicators, which can be customized:
Journal Impact Factor
JIF without Self-Cites
5-Year Impact Factor
Article Influence Score
% Articles in Citable Items
Average JIF Percentile
The All Years journal profile grid can be downloaded using the Export link in a CSV format.
Beginning with the 2022 metrics, released in 2023, all journals in the Web of Science Core Collection will receive a JIF. This extends to the Arts & Humanities Citation Index (AHCI) and Emerging Sources Citation Index (ESCI) for the first time. Additionally, all JIF, JIF without self-cites, 5 Year JIF, and Immediacy Index values will be displayed to 1 decimal point from 2022 onwards. No change is being made to earlier years.
JIF values that would round down to 0 will be displayed as <0.1 going forward.
The interactive graph above shows the Journal Impact Factor (JIF) and JIF Percentile Rank for the last five years in category. Hover over any point in the graph to see values.
The JIF trend is represented as a bar graph, and corresponds to the left-hand axis.
The JIF Percentile in Category is represented as line-and-marker graph, and corresponds to the right-hand axis. The 75th percentile gridline marks the lower boundary of the top quartile journal rank; the 50th percentile gridline marks the lower boundary of the second quartile journal rank; the 25th percentile gridline marks the lower boundary of the third quartile. Journals with a percentile rank below 25% are in the bottom quartile in that category.
Prior years are presented in ascending order, from the four years prior to the current JIF year to the current year. The current year JIF is highlighted, and represents the value shown above the graph. Hovering over any individual year displays the JIF for that year and the JIF Percentile rank for each category. Clicking any category in the legend will change the graph to show data for that category.
To see the full history of both JIF, JIF Percentile, and category assignment for a journal, click the View all years link.
The graph can be exported in a PDF format using the export link.
Beginning with the 2022 metrics released in June 2023, titles indexed in the Arts & Humanities Citation Index (AHCI) and the Emerging Sources Citation Index (ESCI) will have JIFs calculated. Only one year is being calculated for 2022; these journals will not have trend data to display until the 2023 release in June 2024.
Journal Impact Factor data for previous years is only displayed for journals in the Science Citation Index Expanded (SCIE) and the Social Science Citation Index (SSCI).
The tabbed Journal Impact Factor contributing items table displays:
Citable items – the full list of documents from the previous two years, their open access status, and their citation count (for the JIF year). These documents contribute the JIF calculation numerator (citations for JIF year) and denominator (number of citable items). Click any item to see more information or to view the full record in the Web of Science.
Citing Sources – the journals titles that generated the citations used in the JIF calculation for the JCR year. Click any source title to see the list of citing articles from that source. Click on the citing article to see the individual cited reference details. Both linked and unlinked cited references are shown here. Click export on either tab to download the table in CSV format.
Journal Citation Indicator (JCI)
The Journal Citation Indicator (JCI) is displayed in the profile for all titles covered in the Journal Citation Reports. The JCI was introduced in 2021 with the release of the 2020 metrics and was calculated back to 2017.
The JCI trend is represented as a bar graph.
The interactive graph shows the last five JCR years. The current year is highlighted and represents the value shown above the graph. Hovering over any years displays the JCI for that year.
The JCI is a normalized indicator and is not category dependent, journals in multiple categories will have a single JCI. The average JCI of any category is approximately 1.
Total Citations and Citation Distribution
The bar chart of Total Citations shows the total number of times that a journal has been cited by all Web of Science Core Collection sources included in the database in the JCR year. To see more data, click View all years .
The graph can be exported in a PDF format using the export link in the top right of the Total Citations tile
The Citation Distribution shows the frequency with which items published in the year or two years prior were cited in the JCR data year (i.e., the components of the calculation of the JIF). The graph has similar functionality as the JIF Trend graph, including hover-over data for each data point, and an interactive legend where hovering over a data element’s legend highlights that element in the body of the graph. In this way, users can view the specific contributions of Articles, Reviews, or Non-Citable (other) items to the JIF numerator.
Article Citation Median shows the median citation count in the JCR year for all items with the document type “Article” and published in the year or two years prior to the JCR data year. These items are counted in the JIF denominator as “citable items.” A journal that has an Article Citation Median value of “n/a” has no materials in the JCR denominator with the article document type.
Review Citation Median shows the median citation count in the JCR year for all items with the document type Review and published in the year or two years prior to the JCR data year. These items are also counted in the JIF denominator as “citable items.” A journal that has a Review Citation Median value of “n/a” has no materials in the JCR denominator with the review document type.
Items included in the Other category on the graph comprise the non-scholarly materials in the journal, including such things as Editorials, news items, correspondence, corrections, obituaries, etc. These are considered non-scholarly and are not counted as part of the denominator of the JIF, however, they may receive citations. Citations to the non-scholarly content are an important part of how the journal influences the scholarly literature, and are included in the JIF numerator.
Non whole-number medians are rounded up to the next highest whole number value to simplify display.
The number of unlinked citations is shown next to the graph on the left. The number and type of items that received no citations in the JIF year (Times cited = 0) is displayed on the right.
This shows the contribution of open access (gold) to journal impact and how open access content contributes to a journal’s citations.
The two donut charts show a breakdown for published items and citations to those items. These charts cover items published in the journal in the JCR data year and in the previous two years. The count of citations is current up to the date of the JCR extraction.
For example, in the 2022 JCR data, released in June 2023, the Open Access data shows the publication model (OA or subscription/free to read) of materials published in 2020, 2021, 2022, and citations in 2022 to these items.
The identification of the OA types comes from Our Research (formerly ImpactStory), the same source used for Web of Science and InCites Open Access identification.

JIF and JCI Rank
The table ranks the journal by Journal Impact Factor (JIF) in its category by JCR year, or where a journal is in multiple categories, each category and corresponding edition (Science Citation Index Expanded or Social Science Citation Index). The list can be scrolled to view data from earlier years. The JIF rank, JIF quartile and JIF percentile are shown for each year (percentiles and quartiles are by rank). The current JCR year is highlighted and the rank for each category displayed at the top of the table.
Journals indexed in AHCI and ESCI are receiving a JIF for the first time with the 2022 metrics, released in June 2023. They will not however receive a rank, quartile, or percentile. These values will be calculated with the release of the 2023 metrics in June 2024. Learn more here .
The table ranks the journal according to the Journal Citation Indicator (JCI) in its category by JCR year, where a journal is in multiple categories, each category and corresponding edition (Science Citation Index Expanded or Social Science Citation Index). The list can be scrolled to view data from earlier years. The JCI rank, JCI quartile and JCI percentile are shown for each year (percentiles and quartiles are by rank). The current JCR year is highlighted and the rank for each category displayed at the top of the table.
Content metrics provide information about the source items and contributions to the Journal Citation Reports
Source Data - shows the number of citable items in the JCR year.
Average JIF Percentile - this takes the sum of the JIF Percentile rank for each category under consideration, then calculates the average of those values. Individual category values are also shown.
Contributions by organizations - those that have contributed the most papers to the journal in the most recent three-year period.
Contributions by country/region - those that have contributed the most papers to the journal in the most recent three-year period.
Data for each tile can be downloaded using the Export link in a CSV format.
These are complementary metrics to help users better understand journal performance. Each tile shows data in a bar chart format for the previous five JCR years (where available).
Eigenfactor Score - this is a reflection of the density of the network of citations around the journal using 5 years of cited content as cited by the Current Year. It considers both the number of citations and the source of those citations, so that highly cited sources will influence the network more than less cited sources. The Eigenfactor calculation does not include journal self-citations.
Normalized Eigenfactor Score - this is the Eigenfactor score normalized, by rescaling the total number of journals in the JCR each year, so that the average journal has a score of 1. Journals can then be compared and influence measured by their score relative to 1.
Article influence Score - this normalizes the Eigenfactor Score according to the cumulative size of the cited journal across the prior five years. The mean Article Influence Score for each article is 1.00. A score greater than 1.00 indicates that each article in the journal has above-average influence.
Immediacy Index - this is the count of citations in the current year to the journal that reference content in this same year. Journals that have a consistently high Immediacy Index attract citations rapidly.
Beginning with the 2022 metrics, released in 2023, all journals in the Web of Science Core Collection will receive a JIF. This extends to the Arts & Humanities Citation Index (AHCI) and Emerging Sources Citation Index (ESCI) for the first time. Additionally, all JIF, 5 Year JIF, and Immediacy Index values will be displayed to 1 decimal point from 2022 onwards. No change is being made to earlier years.
This displays a breakdown of the journal’s articles by Open Access (OA) type.
For a hybrid journal, one that publishes both OA content and subscription content, users can easily identify the number of articles published under a subscription access model and identify those published under Creative Commons licenses (gold open access).
The goal is to increase transparency around how these articles contribute to a journal’s citations.
The data included in these tiles summarizes the items published in the journal in both the JCR data year and the previous two years. For example, in the 2022 JCR data, released in June 2023, the open access data shows the publication model (OA or subscription) of materials published in 2020, 2021 and 2022, and citations in 2022 to these items.
The identification of the open access types comes from Our Research, the same source used for Web of Science and InCites open access identification.
Classifications Used in Web of Science
In the Web of Science Core Collection, we use a data feed from Our Research to identify five types of open access papers:
Gold - Hybrid
Free to Read
JCR uses only Gold OA for the donut graphs on the profile page. Additional OA data can be viewed on the Web of Science platform.
OA Classifications used in JCR
To show the relationship between OA status at publication and citations in the JCR data, the two gold OA types are grouped together. The Gold OA label on the JCR profile page refers to papers tagged as Gold or Gold - Hybrid in the Web of Science Core Collection. The data are current as of the time of JCR extraction from the Web of Science.
Subscription and Free to Read
Articles in the Web of Science identified as Free to Read (formerly Bronze)are labeled as such in the JCR. This is a relatively recent term, used by Our Research to describe content that is free to read on the publisher site, but not published under an OA license. Papers that are categorized as Green Published and Green Accepted in Web of Science are often subject to an embargo after initial publication and available to subscribers only for that time; these are included in the Subscription and free to read group.
All materials indexed as articles or reviews in Web of Science are counted as Citable Items in the denominator of the Journal Impact Factor (JIF) and the Immediacy Index. They represent the scholarly contribution of a journal to the literature. Citations to citable items account for nearly 98% of citations linked to journal content in Web of Science.
Any substantive, indexed item in the journal, such as editorial material, correspondence, news, meeting abstracts, etc., are non-citable items. These items are not counted as part of the scholarly content in the JIF denominator, and are grouped as other content in the JCR.
Citations in the JCR are aggregated according to the journal title, independently of whether they are linked to an individual item in the journal. Although the rate of linked citations can vary between journals, over 95% of citations in the JCR are linked to an item in the journal. Unlinked citations are included in all JCR citation metrics and are displayed specifically in the citation chart, therefore, it is important they are represented in the descriptive citation data in the OA data.
The current data was extracted from Our Research in April 2021 and will be periodically updated from the date of the release onwards

On this page you will find a suite of citation-based metrics for Nature Portfolio journals, produced by Clarivate Analytics. Brief definitions for each of the metrics used to measure the influence of our journals are included below the tables . Article-level metrics are also available on each article page, allowing readers to track the reach of individual papers.
Commentaries on Impact Factors and their use and misuse can be found in our editorials and other content, going back for many years, links to a sample of which are provided at the end of the page .
For recently launched journals, metrics are calculated from available citation data. If a metric uses multiple years of data, new journals may have partial metrics.
While the metrics presented here are not intended to be a definitive list, we hope that they will prove to be informative. The page is updated on an annual basis.
2-year Impact Factor:
The Journal Impact Factor is defined as all citations to the journal in the current JCR year to items published in the previous two years, divided by the total number of scholarly items (these comprise articles, reviews, and proceedings papers) published in the journal in the previous two years. (Courtesy of Clarivate Analytics )
5-year Impact Factor:
The 5-year journal Impact Factor, available from 2007 onward, is the average number of times articles from the journal published in the past five years have been cited in the JCR year. It is calculated by dividing the number of citations in the JCR year by the total number of articles published in the five previous years. (Courtesy of Clarivate Analytics )
The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. (Courtesy of Clarivate Analytics )
The Eigenfactor Score calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals. References from one article in a journal to another article from the same journal are removed, so that Eigenfactor Scores are not influenced by journal self-citation. (Courtesy of Clarivate Analytics )
Article Influence Score:
The Article Influence Score determines the average influence of a journal's articles over the first five years after publication. It is calculated by multiplying the Eigenfactor Score by 0.01 and dividing by the number of articles in the journal, normalized as a fraction of all articles in all publications. This measure is roughly analogous to the 5-Year Journal Impact Factor in that it is a ratio of a journal's citation influence to the size of the journal's article contribution over a period of five years.

Impact Factor (IF) is a measure reflecting the average number of citations to articles published in science and social science journals. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones.

Journal Citation Reports (JCR): Clarivate Announces Changes to Journal Impact Factor Category Rankings
From a Clarivate Blog Post:
Over the past few years, we have implemented a series of policy changes for the Journal Citation Reports (JCR)™ aimed at aligning coverage between the Web of Science Core Collection™ and the JCR, providing more transparency of the data underlying JCR metrics encouraging a more inclusive, more holistic way of comparing journals. [Clip] Recent changes to the JCR have included the addition of profile pages for journals indexed in the Arts and Humanities Citation Index (AHCI)™ and Emerging Sources Citation Index (EHCI)™ and the introduction of the Journal Citation Indicator (JCI) in 2021. The JCI is field-normalized to facilitate the comparison of journals across different disciplines, including the arts and humanities. We also extended the Journal Impact Factor (JIF)™ to AHCI and ESCI journals in 2023 so that it now encompasses all quality journals in the Web of Science Core Collection. [Clip] In making these changes, we have evolved the JIF from an indicator of scholarly impact (the numerical value of the JIF) in the sciences and social sciences to an indicator of both scholarly impact and trustworthiness (having a JIF – regardless of the number) across all disciplines at the journal level. In 2023, we also changed the way the JIF is displayed – transitioning from three decimal places to one. This is important as it created more ties in JIF rankings to encourage consideration of additional indicators and descriptive factors alongside the JIF when comparing journals. Our commitment to enhancing transparency and trust continues in the forthcoming JCR release in June 2024. Two notable changes, which we announced last year , will be implemented in the JIF category rankings. We will move from edition-specific category JIF rankings to unified rankings for each of our 229 science and social science categories. We will no longer provide separate JIF rankings for the nine subject categories that are indexed in multiple editions. For example, the Psychiatry category is included in both Science Citation Index – Expanded (SCIE)™ and Social Sciences Citation Index (SSCI)™ and we currently publish a separate Psychiatry ranking for each edition. We will replace these separate rankings with a single, unified ranking. Additionally, the new unified rankings will include journals indexed in ESCI. Using Psychiatry once again as our example – we will display a single Psychiatry ranking that includes journals indexed in SCIE, SSCI and ESCI. [Clip] This is the first in a series of updates on the 2024 JCR.
