Supplementary data about languages used by the langcodes module
Decision gist · record as of 2026-08-14
Yes, if you depend on langcodes—it is a required dependency. Install it standalone only if you need direct access to CLDR language data. No known vulnerabilities, permissive license, and active maintenance make it safe to depend on.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
language_data is a data package that stores multilingual language names, speaker population estimates, and writing population estimates extracted from Unicode CLDR version 40. It is designed as a supplement to the langcodes module and uses marisa-trie for efficient lookup of language names across many languages.
The package includes caveats about its data: writing population estimates can be overestimates based on literacy rates rather than actual writing behavior, Chinese writing systems obscure distinctions between spoken varieties, and sign languages have zero population estimates because CLDR lacks that data.
Use it for
- Retrieve multilingual names for language codes in applications needing localized language labels
- Access speaker and writer population estimates for demographic context in language-aware applications
- Build language selection interfaces that display language names in the user's own language
- Enrich language metadata in NLP or localization pipelines using standardized language codes
