For the study, the researchers conducted what they say is a first-of-its-kind analysis of trend data from 188 countries. More than 50 percent of the world’s 671 million obese people live in just 10 of those countries:
- United States
The highest proportion of the world’s obese people, 13 percent, live in the United States. China and India together represent 15 percent of the world’s obese population. Rates in the study were age-standardized, meaning they were adjusted for differences in population size and ages over time and across countries.
