Language is a major source of systemic inequities in science, particularly among scholars whose first language is not English. Studies have examined scientists’ linguistic practices in specific contexts; few, however, have provided a global analysis of multilingualism in science.
Using two major bibliometric databases (OpenAlex and Dimensions), we provide a large-scale analysis of linguistic diversity in science, considering both the language of publications (N = 87,577,942) and of cited references (N = 1,480,570,087).
For the 1990–2023 period, we find that only Indonesian, Portuguese, and Spanish have expanded at a faster pace than English. Country-level analyses show that this trend is due to the growing strength of the Latin American and Indonesian academic circuits. Our results also confirm the same-language preference phenomenon (particularly for languages other than English), the strong connection between multilingualism and bibliodiversity, and that social sciences and humanities are the least English-dominated fields.
Our findings suggest that policies recognizing the value of both national-language and English-language publications have had a concrete impact on the distribution of languages in the global field of scholarly communication.
