“A top insurer in the North Carolina Obamacare exchange reported that its customers are both older and less healthy than it expected and warned that premiums are likely to rise next year.

“Not as many of the state’s young and healthy enrolled as expected,” Blue Cross Blue Shield of North Carolina announced in a press release. The company expected 50 percent of its Obamacare exchange customers to be younger than 35, but just 32 percent of customers are below age 35 and just 25 percent are between the ages of 18 and 34.”
