A survey by a private healthcare foundation says 80 million people, around 43 percent of America's working-age adults, didn't go to the doctor or access other medical services last year because of the cost.
That's up from 75 million people two years ago. Not surprisingly, those who were uninsured or had inadequate health insurance were most likely to have trouble affording care, but 28 percent of working-age adults with good insurance also had to forgo treatment.
