Global disparities in knowledge production and papers’ localization. (Top) Five-group classification of the total number of mentions of country names and demonyms in the analytical sample. (Bottom) Five-group classification of countries based on the localization rate of studies that mention a country name or demonym in their abstract. For both panels, the five categories are obtained by applying Jenk’s algorithm to the country-level number of mentions and localization rates, respectively. Jenk’s algorithm minimizes the variance within categories and maximizes the variance between categories.
