SCImago Journal & Country Rank (SJR) is a free public portal that provides journal rankings, country research performance metrics, and subject-level analytics, built using data from Scopus (Elsevier’s large abstract and citation database). Developed by the SCImago Research Group, it is widely used by researchers, institutions, and policymakers to evaluate scientific influence and output.
Key Features
- SJR Indicator: A prestige-based metric that measures a journal’s impact by weighting citations based on the source journal’s influence (similar to PageRank).
- Journal Rankings:
- Covers tens of thousands of journals across all scientific fields
- Organized into subject areas and categories
- Shows quartiles (Q1–Q4), H-index, total documents, citations, and more
- Country Rankings:
- Research output and citation metrics by country
- Field-specific national strengths
- Discipline Trends:
- Insights into how scientific domains evolve globally
- Open access:
- Full browsing and ranking tools available free to all users
Use Cases
- Evaluating where to publish research
- Benchmarking journals during grant or tenure assessments
- Understanding scientific output of countries and institutions
- Comparing impact metrics across disciplines
- Tracking long-term trends in fields or journals
Why It Matters
SJR helps democratize access to scholarly analytics by offering free journal and country metrics, typically locked behind commercial solutions like Journal Citation Reports (JCR) and SciVal. Because it draws from Scopus data and uses a more nuanced citation-weighting system, many researchers prefer SJR when assessing journal prestige, influence, or the visibility of their field.
