There are substantial differences in uninsured rates for different groups, with people with lower incomes, people in rural communities, and racial and ethnic minorities being most likely to lack health insurance coverage. 

Lack of health insurance coverage may negatively affect health particularly by restricting an individual’s access to health care services.  Uninsured adults are less likely to receive preventive services for chronic conditions and children without health insurance coverage being less likely to receive appropriate treatment for conditions like asthma or preventive services such as dental care, immunizations, and well-child visits.  Out-of-pocket medical care costs may lead individuals to delay or forgo needed care and medical debt is common among both insured and uninsured individuals. 

In Arkansas 25 percent of working-age adults have no health insurance.
