Status of the uninsured

Based on self-reported census data, in 2010, more than 49 million people in the US (more than 16% of the population) were without health insurance as defined in the questions asked. The percentage of the non-elderly population who are uninsured has been generally increasing since the year 2000. Among the uninsured population, some 40 million were employment-age adults (ages 18 to 64), and more than 28 million worked at least part-time. About 37% of the uninsured live in households with incomes over $50,000.

According to the Census Bureau, more than 40 million of the uninsured are US citizens. Another 9.7 million are non-citizens, but the Census Bureau does not distinguish in its estimate between documented and undocumented migrants. It has been estimated that nearly one fifth of the uninsured population is able to afford insurance, almost one quarter is eligible for public coverage, and the remaining 56% need financial assistance (8.9% of all Americans). An estimated 5 million of those without health insurance are considered "uninsurable" because of pre-existing conditions.


The costs of treating the uninsured must often be absorbed by providers as charity care, passed on to the insured via cost-shifting and higher health insurance premiums, or paid by taxpayers through higher taxes.
