The numbers are staggering.
According to the Center for Disease Control, the past 20 years has seen a dramatic increase in obesity in the United States. In 2010, no state had a prevalence of obesity less than 20%. Thirty-six states had a prevalence of 25% or more; 12 of these states (Alabama, Arkansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Oklahoma, South Carolina, Tennessee, Texas, and West Virginia) had a prevalence of 30% or more.
The data shown in these maps were collected through the CDC’s Behavioral Risk Factor Surveillance System (BRFSS), on the basis of self-reported weight and height. Each year, state health departments use standard procedures to collect data through a series of monthly telephone interviews with U.S. adults.
