About World Languages Catalog | Methodology, Editorial Standards, and Sources

Mission

World Languages Catalog documents major world languages and selected regional languages in a structured, comparable format. Our goal is to make language information easier to verify, compare, and cite.

We focus on practical linguistic literacy: where a language is used, how it is classified, what writing systems it uses, how dialect variation appears, and how vitality should be interpreted responsibly.

What Makes This Project Different

Each profile is designed as a standalone reference page with unique metadata, structured headings, cited sources, internal links, and editorial notes. We separate L1 native-speaker estimates from wider L2 usage to avoid misleading comparisons.

We prioritize stability and indexability so each page remains crawlable and meaningful to both search engines and readers.

Use verifiable sources for counts, classification, and vitality statements.
Distinguish evidence from interpretation when historical or classification debates exist.
Avoid unqualified demographic claims when methods differ across data providers.
Publish updates when material factual errors are confirmed.
