Language bias in global university rankings

English as the default language of rankings

Global university rankings are produced in English, rely on English-language data sources, and are consumed primarily by an English-speaking audience. This linguistic centering creates a systematic advantage for universities in English-speaking countries and for institutions anywhere that prioritize English-language publication. The bias is not intentional—it is structural, embedded in the data infrastructure on which rankings depend.

The major bibliometric databases that feed ranking indicators, such as Scopus and Web of Science, index primarily English-language journals. Research published in Chinese, Japanese, German, French, Spanish, Arabic, or any other language is underrepresented, regardless of its quality or its relevance to local and regional communities. A landmark study published in a leading Chinese-language journal may have more real-world impact than a middling paper in an English-language journal, but it will contribute nothing to the university's citation metrics.

Reputation surveys and linguistic visibility

Language bias also affects reputation surveys. When tens of thousands of academics worldwide are asked to name the top institutions in their field, they are more likely to name institutions whose work they can read and whose names are familiar. This gives an advantage to universities that publish heavily in English and that have invested in global brand visibility. A university that does excellent work but publishes primarily in a language other than English may be largely invisible to the international academic community that fills out reputation surveys.

The survey instrument itself introduces bias. If the survey is administered in English, academics who are not fully comfortable in English may be less likely to respond, or their responses may be influenced by the language in which the questions are framed. If the survey asks respondents to list institutions without specifying a geographic scope, respondents are likely to think of institutions in their own region first, but the aggregation of responses across regions gives disproportionate weight to regions with more survey respondents.

The consequences for non-Anglophone systems

The consequences of language bias are most severe for higher education systems in non-English-speaking countries. Universities in China, Japan, Korea, Germany, France, Latin America, and many other regions may be systematically undervalued in global rankings because their research output is published in local languages. This undervaluation has real-world effects: it influences international student recruitment, faculty mobility, research partnerships, and institutional prestige.

Some countries have responded by incentivizing English-language publication, sometimes at the expense of research that addresses local needs and engages with local scholarly communities. A researcher studying a region-specific issue may face a choice between publishing in English for an international audience that has little context for the issue, or publishing in the local language for an audience that can directly use the findings. Rankings reward the first choice, even though the second may have greater real-world impact.

Reading rankings with language awareness

When using global rankings to evaluate universities in non-English-speaking countries, be aware that the rankings may understate their research strength. A university that appears modestly ranked globally may be a national or regional leader whose excellence is not fully captured by English-language indicators. If you are considering studying in a non-English-speaking country, look for national rankings, government quality assessments, and field-specific evaluations that use more appropriate data sources.

Also consider the language of instruction. If you plan to study in a language other than English, the university's position in English-language rankings is particularly irrelevant to your experience. You should focus on assessments that evaluate the quality of instruction in the language you will be studying in, using criteria that are appropriate to that educational system. Rankings are useful tools, but they are tools built for a specific purpose, and that purpose does not always align with the needs of every user.

In the long run, ranking publishers face a choice: adapt their methodologies to capture the linguistic diversity of global higher education, or accept that their products will increasingly be seen as Anglo-centric measures of a particular kind of institution rather than truly global comparisons. Until that adaptation happens, users must supply their own corrections, reading English-language rankings with full awareness of the linguistic lens through which they were produced.

For multilingual students, language bias has an ironic twist: you may be uniquely positioned to discover excellent universities that Anglophone ranking systems undervalue. Your ability to read and engage with scholarship in languages other than English opens doors to institutions and programs that monolingual ranking users might never find.
