Why do we measure obesity?
More than one-third of adults in the United States are obese (body mass index of 30 or higher), and obesity is linked to wide-ranging health problems.(1) Conditions associated with obesity include type 2 diabetes, cardiovascular disease, high blood pressure, asthma, some cancers, poor mental health, and overall reduced quality of life, which may be exacerbated by associated stigma.(2,3)
Obesity is caused by a combination of genetics, health behaviors — including unhealthy dietary patterns and physical inactivity — and the environment in which people live, such as proximity to retail food outlets.(2) Some communities are disproportionately affected by obesity, particularly low-income and Black, Hispanic and American Indian and Alaska Native populations.(5)
How do we measure obesity?
This metric includes adults 18 or older, who report having a body mass index (BMI) of 30 or higher.(7)
Strengths of Metric | Limitations of Metric |
Using self-reported height and weight, as we do with this metric, is the most reliable method of measurement for a large population.
| BMI does not account for the gender, body composition, build, age, or ethnicity of a person.(6) This metric only gives us a picture of adult obesity, not childhood obesity, which is also a public health concern in the U.S. The metric is self-reported and depends on the accurate reporting of the person surveyed.

Calculation
Obesity is calculated by the following formulas:
This metric was calculated by aggregating estimates from smaller geographies to the congressional district level. For more information, please refer to the Congressional District Health Dashboard Technical Document.
Data Source
Estimates for this metric are from one year modeled PLACES Project Data (formerly 500 Cities Project)from the Centers for Disease Control and Prevention.
Years of Collection
Calculated by the Dashboard Team using data from 2021, 1 year modeled estimate.
