If I am reading this map correctly, 30% of non-elderly adults in Knoxville have a declinable pre-exisiting health condition.

The share of non-elderly adults with a declinable pre-existing condition ranges from 41% in Kingsport, Tennessee to 20% in Logan, Utah and Rochester, Minnesota. The prevalence of pre-existing conditions can vary by 10% or more between cities in the same state. For example, in Kansas 32% of Topeka’s population has a pre-existing condition, as compared to 21% of Manhattan’s population. Similarly, in

South Carolina 34% of Florence residents have a pre-existing condition, compared to 24% in Charleston or Hilton Head.
