This map from The Daily Biz, created using data from the U.S. Census Bureau, shows health insurance rates by county for people under the age of 65 across the United States.

Darker areas represent the counties with higher rates of uninsured Americans, while lighter areas represent the counties with lower rates of uninsured people under age 65.

The higher rates of uninsured Americans can be found concentrated in the Western and Southwestern estates, and in some parts of the Southeast. By contrast, the rate of uninsured Americans is lower in the Northeast and parts of the Southeast and Midwest.
