Adult Obesity Facts

Obesity is common, serious and costly

  • More than one-third (or 78.6 million) of U.S. adults are obese. [Read abstract Journal of American Medicine (JAMA)]
  • Obesity-related conditions include heart disease, stroke, type 2 diabetes and certain types of cancer, some of the leading causes of preventable death. [Read guidelines]
  • The estimated annual medical cost of obesity in the U.S. was $147 billion in 2008 U.S. dollars; the medical costs for people who are obese were $1,429 higher than those of normal weight. [Read summary]

Obesity affects some groups more than others

  • Non-Hispanic blacks have the highest age-adjusted rates of obesity (47.8%) followed by Hispanics (42.5%), non-Hispanic whites (32.6%), and non-Hispanic Asians (10.8%)
  • Obesity is higher among middle age adults, 40-59 years old (39.5%) than among younger adults, age 20-39 (30.3%) or adults over 60 or above (35.4%) adults.

Obesity and socioeconomic status

[Read CDC National Center for Health Statistics (NCHS) data brief [PDF-1.07Mb]

  • Among non-Hispanic black and Mexican-American men, those with higher incomes are more likely to be obese than those with low income.
  • Higher income women are less likely to be obese than low-income women.
  • There is no significant relationship between obesity and education among men. Among women, however, there is a trend—those with college degrees are less likely to be obese compared with less educated women.

Obesity prevalence in 2012 varies across states and regions

  • By state, obesity prevalence ranged from 20.5% in Colorado to 34.7% in Louisiana in 2012. No state had a prevalence of obesity less than 20%. Nine states and the District of Columbia had prevalence between 20-25%. Thirteen states (Alabama, Arkansas, Indiana, Iowa, Kentucky, Louisiana, Michigan, Mississippi, Ohio, Oklahoma, South Carolina, Tennessee, and West Virginia) had a prevalence equal to or greater than 30%.
  • Higher prevalence of adult obesity was found in the Midwest (29.5%) and the South (29.4%). Lower prevalence was observed in the Northeast (25.3%) and the West (25.1%).


The U.S. map has been color coded to indicate the range of obesity prevalence in each state in 2012. No state had an obesity prevalence between 15% to less than 20%. States that had an obesity prevalence between 20% to less than 25% are: Colorado, District of Columbia, Hawaii, Massachusetts, Montana, New Jersey, New York, Utah, Vermont, and Wyoming. States that had an obesity prevalence between 25% to less than 30% are: Alaska, Arizona, California, Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Mexico, North Carolina, North Dakota, Oregon, Pennsylvania, Rhode Island, South Dakota, Texas, Virginia, Washington, and Wisconsin. States that had an obesity prevalence between 30% to less than 35% are: Alabama, Arkansas, Indiana, Iowa, Kentucky, Louisiana, Michigan, Mississippi, Ohio, Oklahoma, South Carolina, Tennessee, and West Virginia. No state had an obesity prevalence equal to or greater than 35%.

The History of State Obesity Prevalence

  • There was a dramatic increase in obesity in the United States from 1990 through 2010.
  • State prevalences prior to 2011 is provided for historical information only.  Historical rates should not be compared to rates from 2011 and forward due to changes in survey methods.
  • No state met the nation's Healthy People 2010 goal to lower obesity prevalence to 15%. Rather, in 2010, there were 12 states with an obesity prevalence of 30%. In 2000, no state had an obesity prevalence of 30% or more. [Read article]
  • The animated map below shows the history of United States obesity prevalence from 1985 through 2010.

Changed System, New Baseline

Like all public health surveillance systems, BRFSS must occasionally change its methods to adapt to the changing world and to maintain validity.  The improvement changes to the BRFSS affect obesity prevalence estimates, and mean that estimates from data collected in 2010 and before cannot be compared estimates from data collected in 2011 and forward. Learn more about the changes to the BRFSS.
