The National Institute of Diabetes and Digestive and Kidney Diseases maintains overweight and obesity statistics online at NIDDK.NIH.gov. Other governmental bodies, such as the Centers for Disease Control and Prevention, also maintain obesity statistics. CDC statistics are online at CDC.gov.
As of 2010, two out of every three American adults is overweight or obese, while one-third of those aged 6 to 19 are overweight or obese. The obesity rates are even higher among various minority populations, with more than three-fourths of Hispanic and black adults being overweight or obese. About 13 percent of black adults are "extremely obese," while only five percent of white and Hispanic adults are in that category.
