“40.3% of adults are obese.”
What we found.
CDC estimated that 40.3% of U.S. adults age 20 and older had a body mass index (BMI) of at least 30 in August 2021–August 2023. BMI relates weight to height. The estimate uses measured values and adjusts for age differences.
Includes the claim, verdict, source, and review date.
The calculator uses BMI as a separately modeled input
ACS does not contain measured height and BMI for the same people. The calculator applies CDC rates separately and shows a range for how the traits might overlap. It does not substitute the national 40.3% result for a custom result.
How the BMI filter works
BMI below 30 is an optional modeled health input. It is not an attractiveness, worth, or compatibility measure.
