Data Sources and Ranking Methodology
The 5th edition of the Research.com Best Social Sciences and Humanities Universities in the World Ranking is primarily based on comprehensive bibliometric data sourced from OpenAlex and CrossRef, along with multiple other reputable data repositories. The citation-based metrics underpinning this ranking were collected as of January 12, 2026, ensuring an up-to-date and robust dataset.
Positions in the ranking are calculated based on the sum of D-indexes (Discipline H-index) across all ranking scholars affiliated with a given institution whose primary publication focus lies within the Social Sciences and Humanities. The D-index is a specialized variant of the H-index that includes exclusively publications and citation data pertinent to the examined discipline, thereby providing a precise measure of scholarly impact in the specific field.
Scope of Research and Qualification Criteria
Our analysis encompassed 279,971 scientist profiles identified from a diverse array of bibliometric sources. Of these, 23,707 scientists specializing in Social Sciences and Humanities were closely examined. To qualify for inclusion, each scientist was required to have a minimum D-index threshold of 30, with the majority of their tier publications focused in the Social Sciences and Humanities domain.
Moreover, each scientist’s awards and achievements within their discipline were factored into the analysis. The D-index threshold for including top researchers was adjusted incrementally by 10, based on the total number of scholars estimated per discipline. This methodology guarantees the inclusion of the top 1% of leading scholars in the ranking. Additionally, there is a stipulated proximity limit of 30% or less between a scientist's general H-index and their D-index, ensuring disciplinary focus and relevance.
Additional Verification Practices
The Research.com team acknowledges that raw bibliometric data alone cannot serve as an absolute tool for evaluating scholarly output. To address this, all scientist profiles were manually verified and cross-correlated against publications from a broad spectrum of trustworthy sources. Although the number of papers published in prominent journals and conference proceedings is not a direct factor influencing a researcher’s position in the Research.com ranking, it serves as a valuable secondary indicator of the scientist’s contribution to their specific area of study.
The ranking itself is established using each researcher's H-index derived from the integrated data of OpenAlex and CrossRef, two of the most prominent and widely respected bibliometric databases available to the research community.
