How Many Authors per Manuscript?
The 1,015 manuscripts in IEEE Access Volume 14 (2026) generated 3,918 individual author records — a mean of 3.86 authors per paper. The distribution is unimodal and right-skewed: the modal value is 3 authors (233 papers, 22.9%), the median is 4, and the interquartile range spans 2 to 5.
Small collaborative teams are the clear norm. Papers with 2–4 authors account for 641 manuscripts — 63.2% of the entire volume. Solo-authored papers represent 6.0% (61 papers), while papers with 5 or more authors make up 25.1%. At the extreme, one paper lists 14 authors, a signature of large multi-institutional or interdisciplinary consortium work.
"63% of all papers come from teams of just 2–4 authors — compact collaboration is the norm, not the exception, in IEEE Access 2026."

Which Subjects Are Most Published?
subject_categories field with zero renaming, grouping, or reclassification.
All 67 distinct categories are preserved exactly as provided. Papers can carry multiple category
tags; counts reflect how many papers were assigned each tag.
Computational and artificial intelligence dominates the volume by a wide margin — appearing in 467 papers (46.0% of all manuscripts). This isn't a marginal lead: the second-ranked category, Computers and information processing, appears in 306 papers (30.1%). The gap between first and second is larger than the gap between second and eighth place.
The data confirms that IEEE Access Volume 14 is, in practice, primarily a journal of applied AI and computing research. Power engineering (132), signal processing (128), and communications technology (122) form a coherent second tier, reflecting the journal's traditional strength in electrical engineering. Biomedical Engineering (67) and Robotics and automation (60) represent the applied life-science and automation communities.

Where in the World Are Authors Publishing From?
author_affiliation entry — the position where country names conventionally appear.
Only clear abbreviation variants were normalised (e.g., "Republic of Korea" → South Korea;
"U.K." → United Kingdom; "Türkiye" → Turkey). Each country is counted once per paper regardless
of how many authors share it. 91 unique countries are represented.
China (182 papers) and South Korea (170) lead by a clear margin, together present in over one-third of all manuscripts. India (115) takes a strong third. The USA (84) and Japan (67) complete the top five.
What stands out is the breadth: 91 countries are represented — a genuinely global journal. Saudi Arabia (52) and Turkey (43) rank sixth and seventh, reflecting rapidly growing engineering research ecosystems in both nations. Among European contributors, Italy (29), Germany (27), the United Kingdom (27), and Spain (26) feature prominently.
Three phases of global contribution
China (182), South Korea (170), India (115), and Japan (67) together account for 53% of all identified manuscripts — a clear reflection of the region's engineering research output.
USA (84), Brazil (41), Saudi Arabia (52), Turkey (43), and key European nations together contribute meaningfully across engineering and computing disciplines.
Beyond the top 20, 71 more countries appear in the dataset — from Kazakhstan and Estonia to Tanzania and Fiji — confirming IEEE Access's genuinely global reach.

Corrected Funding Breakdown
After reclassification, the 1,015 manuscripts split into three meaningful groups: those with genuine external funding, those where the only "funding" was institutional APC payment, and those with no funding entry at all.
Figure 4 — Three-way corrected split. The raw field count of 707 non-null entries yields a misleading 69.7% funded figure; the corrected external funding rate is 51.2%.
| Category | Manuscripts | Percentage | Description |
|---|---|---|---|
| Externally Funded | 520 | 51.2% | Proper government / agency / international programme funding |
| Institutional / APC-only | 187 | 18.4% | University paid own APC or listed internal grant only; no external agency |
| No Funding Mentioned | 308 | 30.3% | funding_agency field is completely blank |
| Total self-funded (rows 2+3) | 495 | 48.8% | No independent external funder identified |
| Grand total | 1,015 | 100.0% |
Which Agencies Actually Funded the Most Papers?
The following analysis covers only the 520 genuinely externally funded papers. Agency names are recorded verbatim from the dataset; where the same body appears under multiple name variants, entries have been counted separately. The NSFC, NRF, and JSPS dominate — perfectly consistent with China, South Korea, and Japan's top-three publishing positions.

IEEE Access APC, Impact Factor, JCR and SCImago Quartile
For authors weighing up an IEEE Access paper, four numbers come up again and again: the IEEE Access APC, the IEEE Access IF (impact factor), the JCR quartile and the SCImago quartile. Here is where the IEEE Access journal stands in 2026.
| Metric | IEEE Access (2026) |
|---|---|
| Publisher | IEEE (Institute of Electrical and Electronics Engineers) |
| Access model | Fully gold open access: every article is free to read |
| Article processing charge (APC) | US$2,160 per article, before taxes, member discounts or waivers |
| Journal Impact Factor (JCR) | 4.2 (2025 impact factor, Clarivate JCR released 2026); 3.6 in the previous release |
| JCR quartile | Q2 |
| SCImago (SJR) quartile | Q1 in Computer Science, Engineering and Materials Science (miscellaneous) |
| ISSN | 2169-3536 |
Is IEEE Access Q1 or Q2?
Both, depending on which ranking you look at. In Clarivate's Journal Citation Reports (JCR), which ranks journals by impact factor, IEEE Access sits in Q2. In SCImago, which ranks journals by its SJR indicator using Scopus data, IEEE Access is Q1 in its broad subject categories. If your university or funder asks for a "Q1 journal", check which list it uses before you count an IEEE Access paper towards that requirement.
What the IEEE Access APC means in practice
The US$2,160 IEEE Access APC is the cost behind every funding decision analysed above. With only 51.2% of papers genuinely externally funded, many authors of this IEEE open access journal pay the APC from their own institution's budget or their own pocket. IEEE offers discounts for IEEE and IEEE society members, and waivers in some cases, so check your eligibility before you submit.
What This Tells Us About Open Access in 2026
The IEEE Access Volume 14 dataset offers a rare ground-level view of how open access actually works in practice — not the idealised version, but the messy, self-reported, institutionally complex reality. Several things stand out.
The APC model creates incentives for ambiguous reporting. When authors are required to name a funding body but their institution simply paid the fee, many enter the institution rather than leave the field blank. This is not fraud — it is a rational response to a form that wasn't designed for their situation. But it produces statistics (like "69.7% funded") that mislead downstream readers and policymakers.
Nearly half of all 2026 papers have no external grant backing. At 48.8%, the self-funded share is not a rounding error. It means that roughly one in two papers in this volume was produced by researchers who either funded their own APC institutionally or received no dedicated research grant support at all. This challenges the assumption that open access mandates automatically unlock a funded author base.
Geography and funding are tightly correlated. The top external funders — NSFC (China), NRF (South Korea), JSPS (Japan) — map almost perfectly onto the top publishing countries. Where national research infrastructure is strong, publication volume follows. Where it is weaker — as suggested by the large self-funded and APC-only share — output may still reach publication but without the resource base that typically underpins high-impact research.
"A journal accepting 1,015 papers in a single volume quarter, from 91 countries, on 67 subject areas — yet nearly half without a single external grant. IEEE Access in 2026 is a mirror of the open access economy itself."
