MDPI’s 2024 Impact Factor Highlights

For those of our readers who are new to academic publishing, you may have heard some news in June around the Impact Factor release. Every year, typically in June, Clarivate releases its annual Journal Citation Reports (JCR), which include Journal Impact Factors (JIF). This metric is widely used in academic publishing to reflect the average number of citations received by recent articles in each journal.

While Impact Factor is just one of many indicators of journal influence, it remains a major milestone for authors, editors, and publishers. It’s used to assess journal visibility, researcher recognition, and scholarly reach. Throughout our international meetings and events, it’s clear that the Impact Factor is something many of our authors and editorial board members care about, as it can influence where they choose to submit an article and the funding they receive for their research.

“These results reflect the trust that the scholarly community places in MDPI”

MDPI’s 2024 Impact Factor Highlights

• 298 MDPI journals received a Journal Impact Factor.
• 60 journals earned their first-ever Impact Factor
• To put this in perspective: MDPI’s 60 new journal acceptances into the Web of Science was the second highest number of any publisher in 2024, behind Elsevier and ahead of Springer Nature. Our 87% acceptance rate for journals submitted to Web of Science shows the strength of our editorial process and our proven ability to develop journals aligned with Clarivate’s 24 evaluation criteria.
• Notably, Textiles, Mathematics, International Journal of Neonatal Screening, Smart Cities, Systems, and Pharmaceutics ranked in the top 10% in their respective categories, highlighting their growing influence and prestige within their academic fields. This shows that high-quality indexing goes beyond visibility; it upholds credibility and trust.
• 193 MDPI journals are now ranked in the top 50% (Q1/Q2) of their subject categories.
• What does this mean, and why is it important? Journals are ranked by quartiles within their field, based on their Impact Factor. Q1 represents the top 25% of journals in their category, Q2 the next 25%, and so on. Being in Q1 or Q2 shows that a journal is performing well relative to other journals in its category. Authors and institutions often look at quartile rankings when choosing where to publish – it’s an important indicator of visibility and recognition, within its respective category.
• 116 of our previously ranked journals increased their Impact Factor.
• 14 MDPI journals achieved an Impact Factor of 5.0 or higher, suggesting a high degree of influence and visibility.

These results reflect our staff's hard work: from our editorial and production teams to our indexing, communications, and data teams, and beyond. This also reflects the trust that the scholarly community places in MDPI, reinforcing the message that when researchers publish with MDPI, they publish with impact.

Open Access with Impact

As the leading fully open access publisher, our journals have received a total of 18.4 million citations in the Web of Science by the end of 2024, reflecting the growing reach and engagement of research published with MDPI. We are committed to making scientific research freely accessible to everyone, everywhere. With the support of more than 4.2 million contributing authors, we’re proud to support the global shift toward open access.

MDPI Journals See Continued Growth in 2024 CiteScore Results

Continuing our indexing updates, I’m pleased to share that MDPI has achieved strong results in the latest CiteScore metrics, released on 5 June by Scopus. These results reflect the collective efforts of our editors, reviewers, authors, and internal teams, with their dedication to quality and visibility in scientific publishing. You can read the full announcement here.

2024 Highlights:

• 322 MDPI journals received a CiteScore (up from 274 last year).
• 283 journals (88%) are ranked in Q1 or Q2 of their subject categories.
• 237 journals (85%) saw an increase in their CiteScore compared to last year.
• 48 journals received a CiteScore for the first time.
• 39 journals are now placed in the top 10% of their subject areas.

“This growth highlights our commitment to supporting open, trusted science”

What is CiteScore and how is it measured?

CiteScore metrics are developed by Elsevier as an alternative to the Impact Factor. They measure the citation impact of journals and can be accessed freely on Scopus. The metric represents the yearly average number of citations to recent articles published in a journal. If you’re interested in learning more about citation metrics and how we use them, check out this blog post.

Why is this important?

These results show the growing recognition for, and impact of, MDPI journals across disciplines. CiteScore rankings help researchers, institutions, and funders assess where high-quality work is being published. This growth improves our journals’ positioning in the publishing landscape and highlights our commitment to supporting open, trusted science.

Inside MDPI

Highlights from the MDPI USA Summit in Boston (5–6 June)

The MDPI Summit train continues! With several Summits already behind us, I think this is a good time to reflect on the purpose of these Summits.

Why do we organize MDPI Summits?

These one-and-a-half-day, invite-only gatherings are designed to improve our relationships with Chief Editors who lead our journals and are respected voices in their fields. The Summits aim to:

1. Share MDPI’s values, achievements, editorial practices, and local market collaborations.
2. Collect feedback on MDPI operations and journal practices.
3. Empower Chief Editors to confidently represent MDPI beyond the Summit.

While Chief Editors know their journals well, these events help them better understand MDPI. We want them to be ambassadors for our brand. The aim is for them to walk away informed, engaged, and equipped to share positively about MDPI throughout their networks.

About the Boston Summit

Held on 5–6 June, our first USA Summit gathered over 25 Chief Editors to learn more about MDPI’s activities and collaborations in the USA. The program included presentations, Q&A, and a panel discussion.

Agenda Highlights:

Moderated by Summer Huggard (Operations Manager [DOM], MDPI), the program featured:

• MDPI Overview and USA Collaboration – Stefan Tochev (CEO, MDPI)
• AI in Publishing and MDPI's Actions – Feichi Lu (Junior Data Scientist, MDPI)

Coming Together for Science

Highlights from the MDPI France Summit in Paris (12–13 June)

We completed our first MDPI France Summit in Paris last week, and it was a special event. Attendees were engaged from beginning to end, remaining after hours to network and collaborate.

Why a France Summit?

We chose to host a France Summit in view of the recent challenges MDPI has faced with the National Centre for Scientific Research (CNRS). What we took away from the event is that our authors and editors very much appreciate and enjoy working with us, but we need to address the concerns raised by CNRS, around Article Processing Charges (APCs) and the funding of gold open access publications.

“Our authors and editors very much enjoy working with us”

Some of the claims made in the June 2023 interview with Alain Schuhl, the Deputy CEO for Science at the CNRS, are simply not factual. For example, they state that MDPI’s “average APC charges per article are now around the same as Springer Nature’s.” Here is the relevant passage, reproduced verbatim:

This is not accurate.

A recent preprint analysing APC data from Elsevier, Springer Nature, Wiley, PLOS, MDPI, and Frontiers (2019–2023) shows that MDPI’s average APCs remain significantly lower than those of Springer Nature and several other major publishers.

The MDPI Summits are part of our outreach and communication efforts to address misconceptions and clarify MDPI’s position as one of the most accessible and affordable major gold open access publishers in the world.

Summit Overview

Held on 12–13 June, the France Summit gathered over 20 Chief Editors to learn more about MDPI’s activities and collaborations in France. Many of these editors are influential in their institutions and professional societies. Several also have connections to CNRS, which makes this an important opportunity to clarify how we operate and build trust through open and transparent communication and hopefully turn our editors into informed advocates of MDPI.

Summit Feedback

The feedback has been very positive, with most attendees completing the post-event survey and all rating the experience as Excellent or Good. A few highlights:

• “The whole thing was highly professional and, above all, provided quantified details that will allow us to better answer questions surrounding MDPI.”
• “The summit was an opportunity to meet personally various people directly engaged in the organization and policies of MDPI, which made it possible to clarify some important points concerning publishing with MDPI.”
• “Very well organized! A great opportunity to see all French MDPI partners and editors.”

Program Highlights:

Moderated by Miruna Adelina Nicolcioiu (Senior Conference Producer), the program featured:

• MDPI Overview and France Collaboration – Stefan Tochev (CEO)
• MDPI Editorial Process and Peer-Review Quality – Dr. Marta Colomer (Public Affairs Specialist)
• Institutional Partnerships and Open Access Funding Models – Becky Castellon (Institutional Partnerships Manager)
• AI in Publishing and MDPI's Actions – Daniele Raimondi (Data Scientist)
• Publication Ethics: Global Trends – Diana Cristina Apodaritei (Research Integrity Specialist)
• Closing Remarks – Stefan Tochev
• Panel Discussion – Diana, Becky, Prof. Dr. Patrick Da Cost, and Stefan

MDPI & France: Facts and Figures

• With over 51,000 publications, France is MDPI's tenth-largest contributor, and fifth largest among EU countries after Italy, Spain, Germany, and Poland.
• As of 2020, the cumulative number of authors from France until April 2025 was 87,592.
• As at April 2025, there are more than 2,800 active Editorial Board Members (EBMs) from France, with 59% having an H-index over 26.
• Among them, 22 serve as Editors-in-Chief (EiC) and 61 as section-Editors-in-Chief (SEiC)
• In 2024, IJMS, JCM, and Molecules were the top three MDPI journals in terms of submissions from French-affiliated authors.

Special thanks to our colleagues from Romanian offices for organizing this successful event.
