“Cites per paper” is a two-year cited-by rate computed from OpenAlex. It is not a Clarivate Journal Impact Factor — we neither compute nor license that metric (how the two differ). Citation rates differ enormously between fields, so compare within a discipline. What the other figures mean: journal quartile, SJR, h-index and article processing charge.

OpenAlex counts about 19.7 citations per paper over two years; Scopus, through Scimago, counts 13.10 per document. The two databases index different journals, documents and citations, so the figures differ. Neither is a Clarivate Journal Impact Factor.
The quartile is the one Scimago prints for each category. Rank is the journal's position by SJR among the journals Scimago lists in that category (#1 is the highest); “—” means we hold no rank consistent with that quartile. The document count is what Scopus indexed that year, which can be lower than a journal's full output. Source: SCImago Journal Rank 2025 edition, from Scopus data (scimagojr.com, CC BY-NC).

Is MMWR Morbidity and Mortality Weekly Report a predatory journal?
Our screening does not flag MMWR Morbidity and Mortality Weekly Report. That is not a guarantee of quality — it means the venue is not on Beall's archive (frozen since 2017) and does not match our name-pattern heuristic. It is listed in Scopus, Web of Science, PubMed, which is a positive signal.
Is MMWR Morbidity and Mortality Weekly Report indexed in Scopus or Web of Science?
Per our venue index, MMWR Morbidity and Mortality Weekly Report appears in: Scopus, Web of Science, PubMed. Index membership changes over time — confirm on the index's own site before relying on it.
What is the impact factor of MMWR Morbidity and Mortality Weekly Report?
Papers in MMWR Morbidity and Mortality Weekly Report are cited about 19.7 times each within two years of publication, and Scimago places it in Q1, with an h-index of 255. Those are the open equivalents: the Clarivate Journal Impact Factor is a proprietary metric we neither compute nor license, so we show the two-year citation rate and Scimago quartile instead — they answer the same question of how heavily the journal is cited. A citation rate is a property of a field as much as of a journal.
What Scimago quartile is MMWR Morbidity and Mortality Weekly Report (Q1, Q2, Q3, or Q4)?
In the Scimago Journal Rank 2025 edition, MMWR Morbidity and Mortality Weekly Report is Q1 in all 5 of its subject categories. By category: Epidemiology: Q1, #3 of 175; Health Information Management: Q1, #3 of 62; Health (social science): Q1, #3 of 388; Health, Toxicology and Mutagenesis: Q1, #3 of 160; Medicine (miscellaneous): Q1, #14 of 2,517. Quartiles split the journals in a subject category into four equal groups by SJR, so Q1 is the most-cited quarter and Q4 the least; MMWR Morbidity and Mortality Weekly Report is cited about 19.7 times per paper over two years, with an h-index of 255.
What is the Web of Science (JCR) quartile of MMWR Morbidity and Mortality Weekly Report?
The Web of Science quartile comes from Clarivate's Journal Citation Reports (JCR), a proprietary product we neither license nor compute — so we cannot state a JCR quartile for MMWR Morbidity and Mortality Weekly Report. The open equivalent is its Scimago quartile, Q1, derived from Scopus citation data. Because JCR ranks against Web of Science and Scimago against Scopus, the two can differ, so check Clarivate's site directly if you need the JCR quartile specifically.
Is MMWR Morbidity and Mortality Weekly Report open access?
Our index records its access status as "gold". Where this is derived from publisher-level signals rather than works-level data it is a heuristic, so confirm on the journal's own site — particularly if an article processing charge matters to you.
