Median OJR

The OpenJournalRank Indicator (OJR) is a free, publicly available metric of a journal’s field-normalized citation impact, computed from open OpenAlex citation data. It compares citations to a journal’s papers from the previous three years with the world average for papers of the same subfield, year and type, so 1.00 is the world average and values can be compared across fields. It is computed with the NCI3 method.

The middle OJR among ranked journals in this category: half score higher, half lower. 1.00 is the world average for papers of the same subfield, year and type.

The dot is this category, the solid tick is the median of all ranked journals and the dashed line is the world average.

Quartile

Quartiles split the ranked journals of the list you are viewing into four equal groups by OJR. Q1 is the top quarter and Q4 the bottom quarter.

They are computed within the list on screen, so a journal can be Q1 in its subfield and Q2 in the global ranking.

Modeling and Simulation ranking, 2003
Rank is the position by OJR within the list on screen; 1 is the highest.	OJR is field-normalized 3-year citation impact: 1.00 is the world average for papers of the same subfield, year and type, so values compare across fields. The badge is the journal’s quartile in this list. OJR	Citations per paper over a two-year window, counted from OpenAlex. It is not field-normalized, so compare it only between journals of the same field. ▲ or ▼ is the change from 2002. This is OpenJournalRank’s own count, not Clarivate’s Journal Impact Factor.	Citable documents (articles, reviews and conference papers) published in 2000–2002, the window the 2003 OJR is computed on. A journal needs at least 30 to be ranked.	Share of the journal’s 2000–2002 papers that are free to read in any open-access form. The green OA tag next to a title marks a fully open-access journal.	List price of the article processing charge in US dollars. “$0 listed” means the listed price is zero; a dash means no price is listed.

Indicator year: 2003. Publication window: 2000–2002. How these summaries are calculated

Ranked journals: 14
Window papers (baseline): 2,382 +65.8% from indicator year 2000
Median OJR: 0.582 -7.0% from indicator year 2000
Rising journals (2025): 4

Window papers are the baseline paper population: citable papers (articles, reviews and conference papers) from 2000–2002 in all journals of the world-average baseline, including non-core journals, counted by each paper’s own subfield. They are not the papers of the ranked journals alone.

How to read these rankings

OJR, the OpenJournalRank Indicator: A field-normalized 3-year citation impact, computed from OpenAlex with the NCI3 method. It divides the citations a journal’s papers received by the world average for papers of the same subfield, year and type, so 1.00 is the world average and 2.00 means twice as many citations as expected. Because it is normalized, it can be compared across fields. Read the methodology
Quartiles: Q1 to Q4 split the ranked journals of the list you are viewing into four equal groups by OJR. A journal’s quartile depends on the list: the same journal can be Q1 in its subfield and Q2 among all journals.
Impact factor (2-year): Citations per paper over a two-year window, counted from OpenAlex. It is easy to compare with familiar impact factors but is not field-normalized, so compare it only within a field. It is not Clarivate’s Journal Impact Factor. Why it differs from the Journal Impact Factor
Rank ranges: Each rank in the latest year carries a likely range from 1,000 resamples of the journal’s papers. Where two journals’ ranges overlap, the data cannot tell them apart, so treat neighbouring ranks as ties.
