- OECD measured, 2006: Age base moves from 17 and over (2003) to 15 and over. source
- OECD self-rep, 2021: OECD break in series: change of source and method. Figures for 2000 to 2015 were a visual self-assessment against four body figures, not reported height and weight. source

Why the numbers differ
- Measured or self-reported. In the 14 countries where OECD holds both kinds of survey for one year, the self-reported figure is lower in 12, by a median of 4.30 percentage points. The widest gaps are Chile in 2009 (25.1% measured, 12.1% self-reported), Hungary in 2019 (33.2% measured, 23.9% self-reported), United Kingdom in 2017 (28.7% measured, 21.0% self-reported). These surveys can have different samples and age limits, and OECD says Chile's self-reported figures for 2000 to 2015 came from a visual self-assessment. Self-reported lines are shown but not counted. (source, retrieved 2026-11-02)
- Age-standardised or crude. WHO's main line weights each age group by the WHO standard population, so countries with different age structures can be compared. A crude figure uses the country's real ages, as most surveys here do. This page's number is age-standardised, so crude surveys count at half weight. WHO's crude figure for 2024 is higher than its age-standardised one in 97 of 199 countries and territories, such as the United States (41.83% against 40.96%), and lower in others, such as Japan (5.19% against 5.90%). (source, retrieved 2026-11-02)
- Survey age limits. WHO covers ages 18 and over, NCD-RisC 20 and over, Eurostat's rows here 18 and over, and OECD aims for 15 and over. OECD's country notes give other limits: 30 and over in Finland's measured series, 25 to 74 in Portugal, 20 to 74 in the United States (age-adjusted), and 21 and over in Israel's self-reported series. Each line's note gives its own. (source, retrieved 2026-11-02)
- WHO and NCD-RisC are one model. WHO's metadata names the NCD-RisC paper for its data and method, but it covers ages 18 and over and publishes both sexes, while NCD-RisC covers 20 and over and publishes women and men. For 2024, WHO's figures for women and men differ from NCD-RisC's by 0.76 percentage points on average, and at most 1.98. The model is counted once. (source, retrieved 2026-11-02)
- Some OECD rows are not surveys. For Argentina, Brazil, China, India, Indonesia, Russia, South Africa, Thailand and Ukraine, OECD's "measured" series is WHO's crude estimate from an earlier release, and for China, India, Indonesia and South Africa its "self-reported" series comes from WHO's World Health Statistics. They are shown but not counted. OECD's "measured" series for South Korea names perceived height and weight for 2022 to 2024, so it is not counted either. (source, retrieved 2026-11-02)
- One survey, two age bands. For 10 European countries OECD's latest self-reported year comes from the same 2019 European Health Interview Survey as the Eurostat line. OECD often uses ages 15 and over and Eurostat's rows use 18 and over, so the OECD figure is usually a little lower. It is shown but not counted. (source, retrieved 2026-11-02)
- Years. The model gives a figure for every year up to 2024, including years with no survey in that country. Survey lines show the year of the latest survey, which can be much older.
Common mistakes
- A modelled figure for 2024 does not mean a survey was done in that country in 2024. WHO's method pools studies and accounts for differences in data across countries and years. (source, retrieved 2026-11-02)
- OECD says the United Kingdom's self-reported figures from 2021 cover England, are adjusted to match measured heights and weights, and are not comparable with other countries. (source, retrieved 2026-11-02)
- BMI is weight in kilograms divided by height in metres squared, so this page counts a ratio of weight to height. (source, retrieved 2026-11-02)
- Do not compare an age-standardised line with a crude one for the same country: set the WHO crude line beside a crude survey. (source, retrieved 2026-11-02)
