- Note: Model estimates for every country and year, including years without a survey. A separate series from adult_obesity_rate, the CDC crude rate for US states from self-reported height and weight, which gives lower values than measurement. Values are served with every decimal WHO publishes. WHO revises these series, past years included, when new national reports or estimates come in, so values can change between retrievals.
