DOAJ 2019: Language analysis

by Hamid Pashaei and Heather Morrison

The analysis of Directory of Open Access Journals (DOAJ) shows that open access journals were published in 85 different languages in 2019. 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.

The most popular languages to publish open access articles in 2019 are listed in the following table.

We analyzed the article processing charge (APC) for the ‘first language’ that OA journals publish articles in, and the results for the top languages are shown below.
