Citation Research and Impact Metrics

Introduction to Country Assessment

Impact analysis by country is limited. So far, we have identified only one metric, Scimago Country Rank (SCR) that collects citation data by countries or regions as a whole.   

What You Need to Know

Scimago uses citation data from Scopus to analyze output of different countries. Countries can be ranked by number of documents, citations, citations per document and an h-index. The user can set subject, regional and date parameters to customize the table. Graphs of the data at both the world and country level are also available.

Important points:

  • Data is extracted from the Scopus database, consequently:
    • Coverage is 1996 to the last full calendar year,
    • Assignment to country appears to be determined by the authors' addresses/affiliations, and  
    • Includes data from journal articles, reviews and conference papers.
  • Data is citation-based numerics, so user cannot see:
    • In which journals the documents are published, and
    • Which authors and/or organizations are producing the documents.
  • Data can be downloaded to Excel file.

Best Uses:

  • Determine how much impact a country or region is having for all subjects or broken down by broad subject categories
  • May be useful to determine countries/regions where possible competitors or collaborators may be located (but actual author/company names will not be available).


  1. Go to Scimago Country Rank page
  2. The default display ranks countries by the number of documents found in the Scopus database
