Geographic Distribution of Open-Source Software Documentation Languages
This page measures three aspects of documentation language use: the proportion of all documentation that is written in languages other than English, the average number of distinct documentation languages found per project, and a ranking of the most frequently used non‑English documentation languages. The data are derived from automated analysis of documentation files in the public repositories of a curated set of major open‑source projects, applying language‑detection algorithms to text‑based docs such as READMEs, wikis and API guides. Understanding these patterns highlights how global collaboration and accessibility are reflected in the linguistic choices of documentation teams, revealing gaps where English‑centric materials may limit worldwide participation.
