While rates of bill problems and medical debt were high among both insured and uninsured adults, those who spent any time uninsured reported the highest rates of difficulties in all categories. More than half (53%) of adults who had spent any time uninsured reported debt or bill problems, compared with 26 percent of people who were insured all year (Figure 5). More than two of five (42%) adults who were without coverage any time during the past year said they had problems paying their medical bills in the past year, more than two and half times the rate reported.
