The national obesity rate remained steady at 26.2% in 2012, compared with 26.1% in 2011, but is still higher than the 2008 average of 25.5%. Across states, obesity rates were statistically unchanged in 2012 when compared with 2011, with the exception of four states. Obesity rates increased in New Jersey, Georgia, and North Carolina while obesity rates in Delaware decreased.

These data, collected as part of the Gallup-Healthways Well-Being Index, are based on respondents’ self-reports of their height and weight, which are used to calculate Body Mass Index (BMI) scores. Americans who have a BMI of 30 or higher are classified as obese. Gallup and Healthways have been tracking Americans’ weight situation daily since January 2008.

Obesity rates continue to be highest in Southern and Midwestern states and lowest in Western and Northeastern states.
