English is the language used by more than 9,500 journals, while Spanish language comes second with more than 2,400 journals, followed by Portuguese (1,731), Indonesia (1,135) and French (897). We analyzed the tendency to charge and average APC by first language listed. The only language with a majority of journals charging APCs was Chinese (54%), followed by Persian (33%) and English (31%). Average APC ranged from 43 USD (Indonesian) to 1,096 USD (English). The second highest APC was Catalan at 331 USD, illustrating a correlation between language and APC, with English language journals at the high end of the range.
