What this page covers
Population data, put in context.
These figures describe national populations, not an individual diagnosis or outcome. They are useful for understanding broad patterns around weight and activity, then asking better questions about your own baseline.
Most weight figures here use body mass index, or BMI. BMI is a screening measure, not a direct measurement of body fat or where it is distributed.
