Measuring Research Impact 2: Stanford's Top 2% Scientists


Stanford's Top 2% Scientists list is an emerging ranking that identifies scholars who have made significant contributions to their respective fields. It is based on an analysis of citation impact across multiple scientific fields and subfields using data from the Scopus database.

The ranking considers scholars who have published multiple highly cited papers. It evaluates the citation impact of their work using various metrics and takes into account both career-long citation impact and the impact in a single recent year. To determine the selection, the list includes the top 100,000 scientists based on their c-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field.


The bibliometric information contained in the Scopus database serves as the foundation for the Stanford's Top 2% Scientists ranking. Scopus is a comprehensive abstract and citation database that covers a wide range of academic disciplines. It provides a wealth of information on scholarly publications, including citation counts, author affiliations, and publication details.
