International Journal of Engineering Education

Engineering education journals

No explicit revenue or CAGR figures were present in the provided search results. The results identify a small, discipline‑focused set of dedicated engineering‑education journals (multiple lists and shortlists across the results), indicating a niche market dominated by university/society journals and a few publisher titles. Using internal sector knowledge: estimate ~20–40 dedicated journals globally; assume typical annual revenue per journal (subscriptions, society support, APCs/institutional access) in the range of roughly $0.25M–$2.5M depending on size and publisher; this yields a plausible total market between ~$5M and ~$100M. Selecting a conservative midpoint for a stable, niche academic segment gives an estimated market size of about $50M (0.05 billion USD). Growth potential is modest—academic journal publishing generally grows low single digits annually while OA and institutionalization of engineering education may add upside—so estimated CAGR is ~4.5%. Estimates are based primarily on the provided lists and commentary about the small number and institutional nature of engineering‑education journals and on conservative internal assumptions about average journal revenue.

Open access journal publishing

Search results show divergent market estimates (USD 2.55B–14.2B for 2025). HTF Market Intelligence explicitly reports a 2025 market size of $3.2B (CAGR 12%), while other market reports show 2.55–14.2B and CAGRs of 7–7.8%. STM data on article-level growth (overall CAGR 4%, Gold OA 16%) indicates continued volume growth. I adopt the HTF 2025 monetary figure (3.2B) as a conservative market-size estimate and a moderate CAGR (≈8%) reflecting the 7–12% range across sources and strong Gold OA article growth.

• Market Size (2025) 3.2 Billion; CAGR: 12.00% (forecast to 2033)
• Global market valued at $14.2 billion in 2025; expected to reach $26.3 billion by 2034 at CAGR of 7.8%
• Open Access Journal Publishing Market was valued at USD 2.55 Billion in 2025; projected to USD 5 Billion by 2035 at CAGR 7%
• CAGR for all articles (2014–2024) is 4%; Gold OA publications CAGR 16% over the period

Higher education research dissemination

Estimate uses reported higher-education market sizes in the search results as anchors (global USD 1,042.3B in 2025; U.S. ~USD 6.84B in 2025) and applies an internal-sector share assumption for research-dissemination platforms/publications (roughly 1.5–2% of global higher-education revenue, consistent with the scale of scholarly publishing and dissemination services). Growth potential (≈10% CAGR) is aligned with the quoted higher-education market growth (≈11% in the sources) while moderating for historical slower growth in traditional scholarly publishing and faster digital dissemination trends.

• The global higher education market size is calculated at USD 1,042.31 billion in 2025; CAGR, 2026 - 2035 11.24%.
• Market Size, 2025 $6.84 Bn; Market Estimate, 2026 $7.62 Bn; CAGR, 2026–2034 11.36%.

Thematic special issues

Search results describe the role and prevalence of journal special issues but contain no explicit market-size data. I used internal sector context: the global scholarly/STM publishing market (~$25–30B) and assumed thematic special issues constitute a small share (≈3–4%) of publisher revenue (APCs, subscriptions, sponsored issues), yielding an estimated market size around $0.75–1.2B, rounded to $1.0B. Growth potential assumes overall scholarly publishing CAGR of ~3% and modestly faster growth for topical/thematic collections driven by demand for curated content and conference-linked issues, giving an estimated CAGR of ~5%. No explicit market-size or CAGR figures for thematic special issues were present in the provided search results.
