• People tend to overstate their height and understate their weight. OHID adjusts the self-reported figures to correct for this, but they are still lower than those from measured surveys: 21% of adults in England were obese in 2024/25 on this measure, compared with 30% in the Health Survey for England. They are best used to compare areas.
• Each year runs from mid-November to mid-November. Estimates for small areas are based on a few hundred people each, so they can change from year to year by chance.
• Body mass index (BMI) is weight in kilograms divided by the square of height in metres. For adults, a BMI of 25 or more counts as overweight and 30 or more as obese; overweight here includes obesity.
