Diabetes prevalence maps

The percentage of adult Americans diagnosed with diabetes has risen steadily for the past 20 years, up to 8 percent of the population in 2008. In some regions of the country, however, the rate is nearly twice that. Since 2004, the Centers for Disease Control and Prevention have released estimates for each county, and mapping that data reveals that there are clusters in states like Alabama and Mississippi, where around one in seven adults is diabetic.
