Open data
Use these files when you need the BMI cut-offs as data, not as a webpage. Skip this page if you want to calculate a personal BMI — use the BMI calculator. Dates are the source capture dates, not the build time.
BMI classification thresholds for WHO, Asia-Pacific, Japan (JASSO) and China (WGOC) are published as a Frictionless Data Package. Last verified 11 June 2026 from the named authorities. License CC-BY 4.0. Not medical advice.
Where do I download the files?
The descriptor is /data/datapackage.json (mirrored at /.well-known/datapackage.json). The table is /data/bmi-standards.csv. Each row names the authority and the source URL we checked.
Who should not treat this as a clinical dataset?
Anyone making an individual diagnosis. These are population screening cut-offs. Children, pregnancy, and high-muscle athletes need a different interpretation — the calculator page says so. Tax and salary figures stay in the page engines until we can publish them with the same capture-date discipline.
