28 percent of insured adults under the age of 64 were uninsured in 2016, according to a Commonwealth Fund survey.
The survey also found that:

• More than half of the uninsured are insured through their employer.
• Nearly one in four insured through their employer are underinsured.
• More than one in four Medicaid recipients were underinsured.
• Half of the underinsured report problems paying their medical bills.
• Individuals with higher deductibles are more likely to report problems paying their medical bills.
• More than 45 percent of the underinsured report skipping care they need because of cost.
• Low-income people and those with chronic health problems are more likely to be underinsured.
