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.

Key figures

Six statistics worth citing.

Each statistic has its own stable link and a direct source, so readers can check the original data.

Methodology & sources

How to read these numbers.

The page uses national U.S. sources published by the Centers for Disease Control and Prevention and the Office of Disease Prevention and Health Promotion. Dates beside each source refer to the report or data period, because the newest published report can describe an earlier survey period.

The Body Metric Lab provides educational, non-diagnostic assessments. This page does not replace medical care, diagnosis or treatment.
