What this measures

Prevalence of obesity among adults, age-standardised, in % of adults. Source: World Health Organization. For this measure, higher is worse.

Adults with a body mass index (weight compared with height) over 30. Adjusted to one age mix, so an older country and a younger one can be compared fairly. Estimated with a statistical model from surveys. It rises with income across the poorer half of the world, then stops rising across the richer half. Adjusting for GDP assumes a straight-line link, so it cannot capture that bend.
